Description: PYRAN-2-ONES AND 5,6-DIHYDROPYRAN-2-ONES USEFUL FOR * TREATING HIV AND OTHER RETROVIRUSES FIELD OF THE INVENTION The present invention relates to compounds useful for inhibiting a retrovirus in a human cell infected with said retrovirus. More particularly, the present invention provides pyran-2-ones and 5,6-dihydropyran-2-ones as HIV-proteinase inhibitors. BACKGROUND OF THE INVENTION During the past decade, acquired immunodeficiency syndrome (AIDS) has progressed from having the status of a medical curiosity afflicting only a small number of individuals to a problem of major proportions, both medically and economically. John Saunders and Richard Storer, "New Developments in RT Inhibitors," DN&P 5(3), April 1992, pages 153-169. WHO figures reveal that more than 360,000 cases of AIDS have been reported worldwide, including nearly 175,000 cases in the U.S.A. Of these, approximately 100,00 worldwide (50,000 in the U.S.A.) were reported in the preceding 12-month period. In the U.S.A., the number of seropositive individuals is thought to be approximately two million, and estimates suggest that 5-10 million people worldwide may be seropositive. Saunders and Storer, page 153. Since the first description of the malady in the early part of this decade, acquired immunodeficiency disease syndrome (AIDS) and its devastating consequences have been subjects of continuous and intense coverage in both the lay and scientific press. Indeed, an edition of Scientific American was entirely devoted to AIDS (Scientific American 289, #4 (1988)), and the literature on the disease and the virus is already so vast as to defy thorough citation. On March 20, 1987, the FDA approved the use of the compound, zidovudine (AZT), to treat AIDS patients with a recent initial episode of pneumocystis carinii pneumonia, AIDS patients with conditions other than pneumocystis carinii pneumonia or patients infected with the virus with an absolute CD4 lymphocyte count of less than 200/mπr in the peripheral blood. AZT is a known inhibitor of viral reverse transcriptase, an enzyme necessary for human immunodeficiency vims replication. U.S. Patent 4,724,232 claims a method of treating humans having acquired immunodeficiency syndrome utilizing 3'-azido-3'-deoxy-thymidine (azidothymidine, AZT). Following the discovery of the anti-HIV activity of AZT, much effort has been focused on a wide variety of other dideoxynucleoside analogues in the search for superior agents. In the case of the 2'.3'-dideoxy series, ddC and ddl have shown potent activity against HIV in vitro and have been evaluated in clinical trials. Saunders and Storer, page 160. The compound ddC is currently being developed by Hoffman-La Roche Co. as a potential anti-AIDS drug. Its limiting toxicity in humans is peripheral neuropathy which is reversible at low doses. Raymond R. Schinazi, Jan R. Mead and Paul M. Feorino, "Insights Into HIV Chemotherapy," Aids Research and Human Retroviruses, Vol. 8, Number 6, 1992, pages 963-990. It has been approved by the FDA for AIDS therapy in combination with AZT. The compound ddl has also been evaluated in clinical trials. Its limiting toxicities are peripheral neuropathy and pancreatitis. It has also been shown to stimulate hepatic glycolysis leading to irreversible liver damage. Schinazi, Mead and Feorino, page 966. It has recently been approved by FDA for the treatment of HIV-1 infections in adults and pediatrics patients who are intolerant to or whose health has significantly deteriorated while on AZT treatment Schinazi, Mead and Feorino, page 966. Among these approved drugs, AZT is currently the only drug that has been shown to decrease the mortality and frequency of opportunistics infections associated with AIDS. Schinazi, Mead and Feorino, page 963. Human immunodeficiency virus (HIV) has long been recognized as the causative agent in AIDS, although a minority opinion to the contrary has been expressed (e.g., P. Duesberg, Proc. Natl. Acad. Sci., USA, 86:755-764 (1989)). Sequence analysis of the complete genomes from several infective and non-infective HIV-isolates has shed considerable light on the make-up of the virus and the types of molecules that are essential for its replication and maturation to an infective species. The HTV protease is essential for the processing of the viral gag and gag-pol polypeptides into mature virion proteins. L. Ratner, et al., Nature, 313:277-284 (1985); L.H. Pearl and W.R. Taylor, Nature, 329:351 (1987). HIV exhibits the same gag/pol/env organization seen in other retroviruses. L. Ratner, et al., Nature, 313:277-284 (1985)); S. Wain- Hobson, et al., Cell, 40:9-17 (1985); R. Sanchez-Pescador, et al., Science, 227:484-492 (1985); and M.A. Muesing, et al., Nature, 313: 450-458 (1985). Reverse transcriptase (RT) is an enzyme unique to retroviruses that catalyzes the conversion of viral RNA into double stranded DNA. Blockage at any point during the tran- scription process, by AZT or any other aberrant deoxynucleoside triphosphate incapable of elongation, should have dramatic consequences relative to viral replication. Much work on the RT target is in progress based, in large measure, upon the fact that nucleosides like AZT are easily delivered to cells. However, the inefficiency of phosphorylation steps to the triphosphate, and the lack of specificity and consequent toxicity, constitute major drawbacks to use of AZT and similar nucleosides having a blocked, or missing, 3'hydroxyl group. The T4 cell receptor for HIV, the so-called CD4 molecule, has also been targeted as an intervention point in AIDS therapy. R.A. Fisher, et al., Nature, 331:76-78 (1988); R.E. Hussey, et al., Nature, 331:78-81 (1988); and K.C. Deen, et al., Nature, 331:82-84 (1988). The exterior portion of this transmembrane protein, a molecule of 371 amino acids (sCD4) has been expressed in Chinese hamster ovary (CHO) cells and Genentech (D.H. Smith, et al., Science, 238:1704-1707 (1987)) has had a product in clinical trials since the fall of 1987. CD4 has been shown to have a narrow spectrum of activity against wild-type virus and so far has failed to control HIV infection in humans. Schinazi, Mead and Feorino, page 963. The idea behind CD4 based therapy is that the molecules can neutralize HIV by interfering with viral attachment to T4, and other cells which express CD4 on their surfaces. A variant on this theme is to attach cell toxins to CD4 for specific binding and delivery to infected cells which display glycoprotein gp-120 on their surfaces. M.A. Till, et al., Science, 242:1166-1168 (1988); and V.K. Chaudhary, et al., Nature, 335:369-372 (1988). Another therapeutic target in AIDS involves inhibition of the viral protease (or proteinase) that is essential for processing HIV-fusion polypeptide precursors. In HIV and several other retroviruses, the proteolytic maturation of the gag and gag/pol fusion polypeptides (a process indispensable for generation of infective viral particles) has been shown to be mediated by a protease that is, itself, encoded by the pol region of the viral genome. Y. Yoshinaka, et al., Proc. Nad. Acad. Sci. USA, 82:1618-1622 (1985); Y. Yoshinaka, et al., J. Virol., 55:870-873 (1985); Y. Yoshinaka, et al., J. Virol., 57:826-832 (1986); and K. von der Helm, Proc. Natl. Acad. Sci., USA, 74:911-915 (1977). Inhibition of the protease has been shown to inhibit the processing of the HIV p55 in mammalian cell and HIV replication in T lymphocytes. T.J. McQuade, et al., Science, 247:454 (1990). The protease (or proteinase), consisting of only 99 amino acids, is among the smallest enzymes known, and its demonstrated homology to aspartyl proteases such as pepsin and rerun (L.H. Pearl and W.R. Taylor, Nature, 329: 351-354 (1987); and I. Katoh, et al., Nature, 329:654-656 (1987)), led to inferences regarding the three-dimensional structure and mechanism of the enzyme (L.H. Pearl and W.R. Taylor, Nature, 329:351-354 (1987)) that have since been bome out experimentally. Active HIV protease has been expressed in bacteria (see, e.g., P.L. Darke, et al., J. Biol. Chem., 264:2307-2312 (1989)) and chemically synthesized (J. Schneider and S.B. Kent, Cell, 54:363-368 (1988); and R.F. Nutt, et al., Proc. Natl. Acad. Sci., USA, 85:7129-7133 (1988)). Site directed mutagenesis (P.L. Darke, et al., J. Biol. Chem., 264: 2307- 2312 (1989); and N.E. Kohl, et al., Proc. Natl. Acad. Sci., USA, 85:4686-4690 (1988)) and pepstatin inhibition (P.L. Darke, et al., J. Biol. Chem., 264:2307-2312 (1989); S. Seel eier, et al., Proc. Natl. Acad. Sci., USA, 85:6612-6616 (1988); C.-Z. Giam and I. Borsos, J. Biol. Chem., 263:14617-14720 (1988); and J. Hansen, et al., EMBO J., 7:1785-1791 (1988)) have provided evidence for HIV protease's mechanistic function as an aspartyl protease. A study has demonstrated that the protease cleaves at the sites expected in peptides modeled after the regions actually cleaved by the enzyme in the gag and pol precursor proteins during viral maturation. P.L. Darke, et al., Biochem. Biophys. Res. Communs., 156:297-303 (1988). X-ray crystal- lographic analysis of the HlV-protease (M.A. Navia, et al., Nature, 337:615-620 (1989)) and a related retroviral enzyme from Rous sarcoma virus (M. Miller, et al., Nature, 337:576-579 (1989)) reveal an active site in the protease dimer that is identical to that seen in other aspartyl proteases, thus supporting the supposition (L.H. Pearl and W.R. Taylor, Nature, 329:351-354 (1987)) that the HIV enzyme is active as a dimer. See also Joseph A. Martin, "Recent Advances in the Design of HIV Proteinase Inhibitors," Antiviral Research, 17 (1992) 265-278. To date, the scientific search for a fully effective and safe means of inhibiting retroviruses in a human hosting such a virus, and thereby effectively treating diseases caused by such a virus, such as acquired immunodeficiency syndrome (AIDS), continues. It is well known in the art that certain undesirable physiological manifestations, such as acne vulgaris, seborrhea, female hirsutism, male pattern baldness and benign prostatic hypertrophy, are the result of hyperandrogenic stimulation caused by an excessive accumulation of testosterone or related active hormones in the target tissues. U.S. Patent 4,377,584, col. 1, lines 18-24. Additionally, the reduction of androgen levels has been shown to have a therapeutic effect on prostate cancer. See, e.g, U.S. Patent 5,017,568, col. 2, lines 4-6. It is also known in the art that the principal mediator of androgenic activity in some target organs is 5α-dihydrotestosterone and related 5α-reduced androgens, and that it is formed locally in the target organ by the action of steroid-5α-reductase. It therefore has been postulated and demonstrated that inhibitors of steroid-5α-reductase will serve to prevent or lessen symptoms of hyperandrogenic stimulation. See, e.g., U.S. Patent 4,377,584, col. 1, lines 38-45. Examples of compounds that are antiandrogens by virtue of their ability to inhibit testosterone-5α-reductase are disclosed in U.S. Patents 4,377,584; 4,760,071; and 5,017,568.

The present invention also provides a pharmaceutical composition comprising a pharmaceutically acceptable carrier and an effective amount of the compound of formula I. Finally, the present invention provides a process for making a compound of the formula CC-5 which comprises: a) reacting a compound of the formula CC-3 with a compound of the formula CC- 2 in a hydrocarbon solvent in the presence of a trialkylamine at an elevated temperatare to yield a compound of the formula CC-4, b) treating the compound of formula CC-4 with a base in a water/alcohol mixture, c) treating the mixture of step b) with an acid to yield the compound of formula CC-5. (Refer to Chart CC below.) The compounds of the present invention are named according to the IUPAC or CAS nomenclature system. The carbon atoms content of various hydrocarbon-containing moieties is indicated by a prefix designating the minimum and maximum number of carbon atoms in the moiety, i.e., the prefix C j -C j indicates a moiety of the integer "i" to the integer "j" carbon atoms, inclusive. Thus, for example, C j -G j alkyl refers to alkyl of one to three carbon atoms, inclusive, or ethyl, ethyl, propyl, and isopropyl. Examples of alkyl of one to nine carbon atoms, inclusive, are methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, and nonyl, and all isomeric forms thereof, straight and branched. Examples of alkenyl of one to five carbon atoms, inclusive, are ethenyl, propenyl, butenyl, pentenyl, and all isomeric forms thereof. Examples of "halo" or "halogen" are fluoro, chloro and bromo. By "amino acid residue" is meant the residue of a naturally occurring amino acid, such as: Alanine, Arginine, Asparagine, Aspartic acid, Cysteine, Glutamine, Glutamic Acid, Glycine, Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Proline, Serine, Threonine, Tryptophan, Tyrosine, Valine, Aspartic acid or Asparagine, Glutamic acid or Glutamine; and synthetic derivatives thereof. These amino acid residues may be in the L- or D- configuration and are readily known and available to those skilled in the art. These amino acid residues (or their N-terminal protected forms) are connected to a free amino group via their C-terminus. The compounds of formula I of the present invention inhibit retroviral proteinases and thus inhibit the replication of the virus. They are useful for treating patients infected with human immunodeficiency virus (HIV) which results in acquired immunodeficiency syndrome (AIDS) and related diseases. More particularly, the compounds of the present invention are useful as novel human retroviral protease inhibitors. Therefore, the compounds inhibit retroviral proteases and thus inhibit the replication of the virus. They are useful for treating human patients infected with a human retrovirus, such as human immunodeficiency virus (strains of HIV-1 or HIV-2) or human T-cell leukemia viruses (HTLV-I or HTLV-II) which results in acquired immunodeficiency syndrome (AIDS) and/or related diseases. The capsid and replicative enzymes (i.e. protease, reverse transcriptase, integrase) of retroviruses are translated from the viral gag and pol genes as polyproteins that are further processed by the viral protease (PR) to the mature proteins found in the viral capsid and necessary for viral functions and replication. If the PR is absent or nonfunctional, the virus cannot replicate. The retroviral PR, such as HIV-1 PR, has been found to be an aspartic protease with active site characteristics similar to those exhibited by the more complex aspartic protease, renin. The term human retrovirus (HRV) includes human immunodeficiency vims type I, human immunodeficiency virus type II, or strains thereof, as well as human T cell leukemia virus 1 and 2 (HTLV-1 and HTLV-2) or strains apparent to one skilled in the art, which belong to the same or related viral families and which create similar physiological effects in humans as various human retroviruses. Patients to be treated would be those individuals: 1) infected with one or more strains of a human retrovirus as determined by the presence of either measurable viral antibody or anti¬ gen in the serum and 2) in the case of HTV, having either an asymptomatic HIV infection or a symptomatic AIDS defining infection such as i) disseminated histoplasmosis, ii) isospsoriasis (Isosporiasis, which is caused by Isospora belli, a coccidian parasite, is a diarrheal illness that occurs in AIDS patients when their CD4 counts get low. There are few if any effective drugs against Isospora or Cryptosporidia, a more common parasite that causes a similar chronic diarrhea and wasting in AIDS patients.), iii) bronchial and pulmonary candidiasis including pneumocystic pneumonia iv) non-Hodgkin's lymphoma or v) Kaposi's sarcoma and being less than sixty years old; or having an absolute CD4+ lymphocyte count of less than 500/mπr in the peripheral blood. Treatment of these patients would consist of maintaining an inhibitory level of the compound used according to this invention in the patient at all times and would continue until the occurrence of a second symptomatic AIDS defining infection indicates alternate therapy is needed. More specifically, an example of one such human retrovirus is the human immunodeficiency virus (HIV, also known as HTLV-III or LAV) which has been recognized as the causative agent in human acquired immunodeficiency syndrome (AIDS), although a minority opinion to the contrary has been expressed, P. Duesberg, Proc. Natl. Acad. Sci. USA, 86:755 (1989). HIV contains a retro viral encoded protease, HIV-I protease, that cleaves the fusion polypeptides into the functional proteins of the mature viral particle, E.P. Lillehoj, et al., J. Virology, 62:3053 (1988); C. Debuck, et al., Proc. Natl. Acad. Sci., 84:8903 (1987). This enzyme, HIV-I protease, has been classified as an aspartyl protease and has a demonstrated homology to other aspartyl proteases such as renin, L.H. Pearl, et al, Natare 329:351 (1987); I. Katoh, et al., Nature 329:654 (1987). Inhibition of HIV-I protease blocks the replication of HIV and thus is useful in the treatment of human AIDS, E.D. Clerq, J. Med. Chem. 29:1561 (1986). Inhibitors of HIV-I protease are useful in the treatment of HlV-infected individuals who are asymptomatic or symptomatic of AIDS. Pepstatin A, a general inhibitor of aspartyl proteases, has been disclosed as an inhibitor of HIV-I protease, S. Seelmeier, et al, Proc. Natl. Acad. Sci. USA, 85:6612 (1986). Other substrate derived inhibitors containing reduced bond isosteres or statine at the scissle position have also been disclosed, M.L. Moore, et al, Biochem. Biophys, Res. Commun. 159:420 (1989); S. Billich, et al, J. Biol. Chem. 263:17905 (1988); Sandoz, D.E. 3812-576-A. Thus, the compounds of the present invention are useful for treating diseases caused by retroviruses, such as human acquired immunodeficiency disease syndrome (AIDS). The compounds are also useful for treating non-human animals infected with a retrovirus, such as cats infected with feline leukemia vims. Other viruses that infect cats include, for example, feline infectious peritonitis vims, calicivirus, rabies vims, feline immunodeficiency vims, feline parvovirus (panleukopenia vims), and feline chlamydia. Exact dosages, forms and modes of administration of the peptides of the present invention to non- human animals would be apparent to one of ordinary skill in the art, such as a veterinarian. The compounds of formula I of the present invention are prepared as described in the Preparations and Examples below, or are prepared by methods analogous thereto, which are readily known and available to one of ordinary skill in the art of organic synthesis.

Either ethyl phenylacetate of formula B-2 (wherein n is 1) or ethyl dihydrocinnamate of formula B-2 (wherein n is 2) is then added to give ethyl 6-phenyl-3,5-dioxohexanoate of formula B-3 (wherein n is 1) or ethyl 7-phenyl-3,5- dioxoheptanoate of formula B-3 (wherein n is 2), respectively. Formation of the pyrone ring in the compound of formula B-4 (wherein n is 1 or 2) is accomplished by heating the compound of formula B-3 (wherein n is 1 or 2, respectively) under reduced pressure. Heating of the compound of formula B-4 (wherein n is 1 or 2) with (±)-l-bromo-l-phenylpropane or treatment with (±)l-phenylpropahol in the presence of boron trifluoride in dioxane gives the desired products of formula B-5 (wherein n is 1 or 2, respectively). CHART C The desired product of formula C-4, which is the compound: 4-hydroxy-6-phenethyl-3- (.alpha. -propyl-p-bromobenzyl)-2H-pyran-2-one, is obtained by heating the pyrone of formula C- 3 (prepared in Chart B as the compound of formula B-4 (wherein n is 2)) with the compound of formula C-2 (wherein R is bromide). The requisite compound of formula C-2 (wherein R is bromide) is obtained by a two-step sequence starting from 4-bromobenzaldehyde, the compound of formula C-l. Treatment of the compound of formula C-l with propylmagnesium bromide affords l-(4'-bromophenyl)-l-butanol, the compound of formula C-2 (wherein R is OH). The resulting alcohol, the compound of formula C-2 (wherein R is OH), is then treated with 48% hydrobromic acid to give the desired bromide of formula C-2 (wherein R is bromide). CHART D O-allylation of 4-hydroxy-6-methyl-2-pyrone, the compound of formula D-l, with cinnamyl bromide is achieved to yield the compound of formula D-2. Claisen rearrangement of the resulting pyrone of formula D-2 is carried out in refluxing toluene to give the vinyl analogue of the formula D-3. Claisen product of formula D-3 is subjected to catalytic hydrogenation to afford the compound of formula D-4. Treatment of the compound of formula D-4 with two equivalents of lithium diisopropylamide in tetrahydrofuran followed by the addition of electrophile, such as benzyl bromide, gives the product of formula D-5, which is the compound: 3-(.a!pha.-ethylbenzyl)-6-phenethyl-4-hydroxy-2H-pyran-2-one. This is the preferred process for preparing this compound. CHART E A variety of analogues may be prepared by employing similar conditions which are used in the preparation of the compound of formula D-5 of Chart D. Under these conditions, 4- bromobenzyl bromide, 2-fluorobenzyl bromide, or allyl bromide are reacted with the dianion of formula E-l (prepared in Chart D as the compound of formula D-4) rapidly to yield the compound of formula E-2 (wherein R is 4-bromobenzyl, 2-fluorobenzyl or 3-propylene), which are the compounds: 6-(p-bromophenethyI)-3-(.alpha.-ethylbenzyI)-4-hydroxy-2H-pyran-2-one; 3- (.aIpha.-ethylbenzyl)-6-(o-fluorophenethyl)-4-hydroxy-2H-pyran-2-one; and 3-(.alpha.- ethylbenzyl)-4-hydroxy-6-(3-butenyl)-2H-pyran-2-one, respectively. However, reacting iodoethane and phenylethyl bromide with the compound of formula E-l would require stirring the reaction mixmre at room temperamre for a few hours to yield the compoimd of formuala E-2 (wherein R is ethyl or phenylethyl), which are the compounds: 3-(.alpha.-ethylbenzyl)-4- hydroxy-6-propyl-2H-pyran-2-one and 3-(.alpha.-ethylbenzyl)-4-hydroxy-6-(3-phenylpropyl)-2H- pyran-2-one, respectively.

Under similar conditions, the compound of formula H-4 (wherein R j is ethyl and R 2 is ethyl) which is the compound: 3- (.alpha.-ethylbenzyl)-l-ethylpropyl-4-hydroxy-2H-pyran-2-one, is obtained by employing two equivalents of ethyl iodide as electrophile.

The corresponding dianion, which is generated from sequential treatment with sodium hydride and n-butyllithium, adds to propiophenone of formula 1-4, which is commercially available, to give methyl 2-(α-ethylbenzyl)-5-hydroxy-3-oxo-5-phenyl-heptanoate of formula 1-5. The methyl ester is then hydrolyzed with sodium hydroxide, and upon acidification with hydrochloric acid, the desired material, 6-ethyl-3-(α-ethylbenzyl)-6-phenyl-tetrahydropyran-2,4-dione of foπnula I- 6, is isolated. CHART J Alkylation of the anion of methylacetoacetate of formula J-l (also used in Chart I as the compound of formula 1-1), which is commercially available, after treatment with sodium hydride, with l-bromo-3-phenylpropane foπnula J-2, which is commercially available, gives methyl 2-(3-phenylpropyl)-acetoacetate of formula J-3.

The methyl ester is then hydrolyzed with sodium hydroxide, and upon acidification with hydrochloric acid, the desired material, 6,6- diethyl-3-(3-phenylpropyl)-tetrahydropyran-2,4-dione of formula J-6, is isolated. CHART K Chart K offers an alternative highly effective way to introduce C-3 substituents on the 4- hydroxy-α-pyrone and 5,6-dihydro-4-hydroxy-2/-'-pyran-2-one nucleus. Allylic carbonates of formula K-2 (a, b and c) and nucleophile 5,6-dihydro-4-hydroxy-2-pyrones of formula K-l (a, b and c) are treated with palladium acetate and triphenylphosphine in toluene at 50 °C to yield compounds of formula K-3 (a, b and c). Representative examples of this reaction follow in Chart K. Also, it is possible to employ allylic carbonates containing substitution in the phenyl ring (Chart K, eq. a,b). In cases where diastereomeric products are possible (Chart K, eq. a,b), chromatographically inseparable mixtures are formed. The final products are obtained via desilylation and reduction. In some cases, it is possible to isolate one diastereomer of the product via successive recystallation. The mother liquors contain a mixmre enriched in the other diastereomer, but attempts to purify them via further recrystallizations may fail. Subsequent chemical manipulations on the substituents at the 6-position of the 5,6-dihydropyran- 2-one ring are performed by those skilled in the art. CHART L Chart L describes a generic procedure for the synthesis of C-3 α-branched substitated 4- hydroxy-2-py rones or 4-hydroxy-5,6-dihydropyran-2-ones. The key reaction involves a palladium catalyzed allylic alkylation of the cyclic β-ketoester nucleophile of foπnula L-l (wherein RJ J and R 3 are defined above) utilizing a silyl substitated allylic carbonate of formula L-2. Subsequent desilylation and reduction of the compound of formula L-3 (wherein R π and R 3 are defined above) affords the desired final products, such as compounds of the formula L-4 (wherein R-^ is phenyl and R 3 is propyl or cyclohexyl; and Rg is hydrogen or hydroxy) which are the compounds: 4-hydroxy-6-propyl-6-phenyl-3-(l-phenylpropyl)-2H-pyran-2-one; 4- hydroxy-6-phenyl-6-propyl-3-[ 1 -(2-hydroxyphenyl)-propyl] -2H-pyran-2-one; and 4-hydroxy-6- cyclohexyl-6-phenyl-3-[l-(3-hydroxyphenyl)propyl]-2H-pyran-2-one.

Treatment of a solution of LL-4 and pyrone LL-5 (which is the same as M-3) in methylene chloride with trifluoroacetic acid gives final product LL-6. Hydrogenation of LL-6 gives the final product LL-7 (3-(α- cyclopropyl((5-aminomemyl)-urfur-2-yl))-4-hydroxy-6-(α-ethylphenethyl)-2H-pyran-2- one)(which is the same as JJ-4). Other alkyl acid chlorides are used in place of cyclopropyl carboxylic acid chloride, which is used in preparing LL-3 from LL-2, to achieve the following coπesponding analogs.

Treatment of MM-7 with phenylsulphonylchloride gives the final product MM-8. Other alkyl acid chlorides and substitated heterocycles are used in place of cyclopropyl carboxylic acid to achieve analogs corresponding to M-3.

Treatment of SS-2 with sodium borohydride in an alcohol solvent gives SS-3. Treatment of a mixture of v SS-3 and SS-4 (which is the same as M-3) in methylene chloride or toluene with an anhydrous acid, such as trifluoroacetic acid or p-toluenesulfonic acid, gives the final product SS-5. Treatment of SS-5 with azasulphene SS-6, S. K. Gupta, Synthesis, p. 39 (1977), then affords the final product SS- 7. In a similar manner, treatment of SS-5 with chlorosulfonic acid followed by addition of aniline also yields SS-7 in a two-step protocol. Aniline substituted by one or more halogen, alkoxy, trifluoromethyl, alkyl, nitro and -CN, is also used in this process to yield substitated analogs of SS-7. CHART TT Pyrone TT-1 (which is the same as Q-l) is treated with two equivalents of lithium diisopropylamide in an ether solvent. An aryl aldehyde is added at low temperatare and the reaction quenched by adding a saturated solution of NH C1. This affords the final product TT- 2.

To that solution is added another equivalent of LDA followed by benzaldehyde to yield the final product TT-4. CHART UU Carboxylic acids UU-1 and UU-7 are prepared by methodolgy described in J. Amer. Chem. Soc. (1981) 103:2127, and Tetrahedron Letters (1986) 27:897. The β-hydroxyl group in both UU-1 and UU-7 is protected by reacting the hydroxy acid with t-butyldimethylsilyl chloride in DMF in the presence of imidazole (or 2,6-lutidine, ethyldiisopropylamine) followed by treatment with aqueous base to yield the free carboxylic acid. The carboxylic acid is treated with oxalyl chloride (or alternate reagent) to yield acid chlorides UU-2 and UU-8. If required, another silyl derived protecting group such as the t-butyldiphenylsilyl group is used, or some other suitable alcohol protecting group. Both UU-2 and UU-8 are reacted with the lithium enolate derived from tert-butylacetate (LDA/THF/-78C) to yield β-ketoesters UU-3 and UU-9. Treatment of UU-3 and UU-9 with H2S04/acetic anhydride/acetone yields UU-4 and UU-10 [Kaneko, Sato, Sakaki, Abe J. Heterocyclic Chem. (1990) 27:25], both of which react with acid chloride UU-5 hot toluene in the presence of triethylamine to give the final products UU-6 and UU-11. Oxidation of UU-6 and UU-11 with Cr0 3 or Swern conditions yield the final products UU-12 and UU-14 both of which when treated with sodium borohydride (or other hydride reagents) give mixtures of diastereomers. Reduction of UU-12 yields UU-6 and UU-13 as a separable mixtare of diastereomers. Reduction of UU-14 yields UU-11 and UU-15 as a separable mixtare of distereomers. The remaining diastereomeric products are prepared using this same strategy but using the (S) acid chloride UU-16 in place of UU-5. CHART W Chart VV is a modified version of Chart L above. This chart describes the palladium catalyzed allylic alkylation of the cyclic β-ketoester nucleophile of formula VV-1 (wherein, eg., R j is phenyl, phenethyl or phenylmethyl; R 2 is phenylmethyl or propyl) utilizing a silyl substitated allylic carbonate of formula VV-2. Desilylation results in the compound of formula W-4 (wherein, eg., R 1 is phenyl, phenethyl or phenylmethyl; R 2 is phenylmethyl or propyl) and subsequent reduction results in the compound of formula VV-5 (wherein, eg., R j is phenyl, phenethyl or phenylmethyl; R 2 is phenylmethyl or propyl). CHART WW This chart describes a generic procedure for the synthesis of the C-3α branched 5,6- dihydropyrones by alkylation with 1,3-diphenyl allyl alcohol. Thus, boron trifluoride etherate catalyzed reaction of the compound of formula WW-1 (wherein, e.g., R j is phenyl, phenethyl or phenylmethyl; R 2 is propyl, phenylmethyl or 2-methylpropyl) with 1,3-diphenyl allyl alcohol (WW-2) provides compounds of the formula WW-3 (wherein, e.g., R j is phenyl, phenethyl or phenylmethyl; R 2 is propyl, phenylmethyl or 2-methylpropyl). Subsequent hydrogenation catalyzed by Pd/C provides the compound of foπnula WW-4 (wherein, e.g., R j is phenyl, phenethyl or phenylmethyl; R 2 is propyl, phenylmethyl or 2-methylpropyl). CHART XX This chart is a variation of Chart WW. The only change is that trans-stilbene oxide replaces 1,3-diphenyl allyl alcohol. This chart describes a generic procedure for the synthesis of C-3α branched 5,6-dihydropyrones by alkylation with trans-stilbene oxide. Thus, boron trifluoride etherate catalyzed reaction of the compound of formula XX- 1 (wherein, e.g., R j is phenethyl; R 2 is propyl) with trans-stilbene oxide (XX-2) provides compounds of formula XX-3 (wherein, e.g., R j is phenethyl; R 2 is propyl). Subsequent hydrogenation catalyzed by Pd/C provides the compound of formula XX-4 (wherein, e.g., R j is phenethyl; R 2 is propyl). CHART YY Racemic 3-phenylpentanoic acid (YY-4) is prepared from hydrogenation using Pd/C of YY-2, and followed by basic hydrolysis of ester YY-3. The ester YY-2 is prepared by an orthoester Claisen rearrangement on cinnamyl alcohol YY-1 using 1,1,1-triethoxyethane. Acid YY-4 is readily resolved by reacting the acid YY-4 with diethyl phosphorylchloride in the presence of triethylamine, yielding an activated acyl intermediate which is then treated with (S)- α-methylbenzyl amine to yield a mixtare of YY-5 and YY-6. YY-5 is obtained diastereomerically pure as a crystalline solid (the other diastereomer YY-6 is in the mother liquors). Treatment of YY-5 with H 3 P0 4 at 150-60°C then yields pure (R)-3-phenylpentanoic acid YY-7 (which is the same as CC-1). The (S)-3-Phenylpentanoic acid is obtained following the above procedures if (R)-α-methylbenzyl amine is used to form the diastereomeric amides of the racemic acid YY-4. CHART ZZ Diethyl malonate (ZZ-1) is alkylated with ethyl iodide to give compound of formula ZZ- 2, which is further alkylated with benzyl bromide to give compound of formula ZZ-3 (Procedures in Organic Syntheses, Coll. V 250). Hydrolysis of ZZ-3 gives the racemic acid ZZ-4. The optically active acids, ZZ-5 (which is the same as W-4) and ZZ-6 (which is the same as X-4), are obtained from fractional crystallization of the racemic acid ZZ-4 with either the R or the S isomer of α-methybenzyl amine. CHART AAA This chart illustrates the Lewis acid catalyzed coupling reaction between 5,6-dihydro- 6,6-disubstitated-2H-pyran-2-ones (AAA-1 wherein, e.g., R j is 2-methylpropyl, R 2 is phenylethyl) and benzhydrol (AAA-2) to provide 3-diphenylmethyl derivatives (AAA-3 wherein, e.g., R j is phenylethyl, R 2 is 2-methylpropyl). CHART BBB Acetic acid (BBB-1) is treated with two equivalents of lithium diisopropylamide in tetrahydrofuran. To that solution is added cyclopropane carboxaldehyde (commerically available). After aqueous workup, racemic BBB-2 is isolated. (R) BBB-2b and (S) BBB-2a are obtained from fraction crystallization of the racemic acid with either the R or S isomer of α- methylbenzyl amine, ephedrine, brucine, strychnine, quinine, cinchonidine, quinidine or cinchonine. Alernatively, aldol condensation using the Evan's strategy (J. Amer. Chem. Soc. (1981) 103, 2127) would also afford pure enantiomers BBB-2a and BBB-2b. BBB-2a is treated with triethylorthoacetate to yield BBB-3 (Helv. Chim. Acta. (1987) 70, 1320). Upon thermolysis of BBB-3, BBB-4 is obtained (Helv. Chim. Acta. (1987) 70, 1320). Treatment of BBB-4 with BBB-5 in the presence of Cuprous iodide (Tetrahedron Letters 1253 (1984)) gives BBB-6. Treatment of BBB-6 with oxalyl chloride in methylene chloride for several hours yields BBB-7. To a hot toluene solution of BBB-7 is added a toluene solution of triethylamine and BBB-8. The reaction is heated for several hours and the solvent is removed via evaporation when thin layer chromatography (silica gel, ethyl acetate) indicates complete consumption of BBB-8. The crude reaction is diluted with a 10/1 mixture of methanol/water followed by addition of sodium carbonate. This then affords BBB-9. Treatment of BBB-9 with a catalytic amount of p-toluenesulfonic acid and several equivalents of methanol in ether yields BBB-10. Treatment of a methylene chloride solution of BBB-10 with p-cyanobenzenesulfonylchloride in the presence of triethylamine affords BBB-11. Alternately, treatment of BBB-3 with BBB-5 in the presence of Cuprous iodide (Tetrahedron Letters 1253 (1984)) gives BBB- 12, which is the enantiomer of BBB-6, and when carried through the analogous steps as BBB-6 yields BBB-13. Furthermore, BBB- 14 and BBB- 15 are substitated for BBB-4 and BBB-3 to prepare the corresponding ethyl stereoisomers. CHART CCC Ketone CCC-1 is treated with (carbethoxymethylene)triphenylphosphorane to yield unsamrated ester CCC-2. Reduction (Red-Al/CuBr, DIBAH/MeCu; NaBH4/resin; NaBH4/Cu2C12; ref. Reduction by the Alumino and Borohydrides in Organic Synthesis, J. Seyden-Penne, VCH Publishers, Inc. Lavoisier - Tec & Doc, 1991, p 156) of CCC-2 followed by ester hydrolysis yields CCC-3. (R) CCC-4a and (S) CCC-4b are obtained from fraction crystallization of the racemic acid CCC-3 with either the R or S isomer of α-methylbenzyl amine, ephedrine, brucine, strychnine, quinine, cinchonidine, quinidine or cinchonine. Alternatively, CCC-4a and CCC-4b are obtained via asymmetric reduction (Angew. Chem. InL Ed. Engl. (1989) 28, 60) followed by basic hydrolysis. Following the protocol described in Chart BBB, CCC-6 is prepared. CHART DDD 2-Thienylamine DDD-1 (commerically available) is treated with 2 equivalents of n-butyl lithium in ether at -78°C. After stirring at -78°C for 30 minutes the reaction temperatare is raised to 0°C for 30 minutes followed by the addition of sultar (fine powder). After aqueous workup, DDD-2 is isolated (J. Amer. Chem. Soc. (1955) 77, 5357, 5446; Org. Syn. Vol. VI, 979 (1988)). DDD-2 is treated with p-fluorophenylsulfonyl chloride in methylene chloride in the presence of triethylamine to yield DDD-3. DDD-3 is also available via first reacting DDD-1 with p-fluorobenzenesulfonylchloride followed by treatment of that intermediate with 2 equivalents of n-butyl lithium in ether followed by the addition of sulfur. Treatment of a mixtare of DDD-3 and DDD-4 in ether with triethylamine affords DDD-5 (US Patent 4968815). Following the same procedure as found in Chart BBB, DDD-5 is converted to an acid chloride and reacted with (R) 2,2-dimethyl-6-(α-ethylphenethyl)-4H-l,3-dioxin-4-one to afford DDD-6. As is apparent to those of ordinary skill in the art, the compounds of the present invention can occur in several diastereomeric forms, depending on the configuration around the asymmetric carbon atoms. All such diastereomeric forms are included within the scope of the present invention. Also, the compounds of the present invention can exist in several tautomeric forms, including the particular enol form as depicted in the Formula Chart below by formula I and the keto form of formula II and mixtures thereof. (For formulas I and π, the dashed line indicates that a double bond may be present or absent.) All such tautomeric forms are included within the scope of the present invention. For compounds of the present invention which are 4- hydroxy-pyran-2-ones of formula IV in the Formula Chart below, the enol form predominates. For compounds of the present invention which are 5,6-dihydro-4-hydroxy-pyran-2-ones of formula III in the Formula Chart below, a mixmre of the enol and keto forms is commonly expected. The compounds of the present invention may be in either the free form or the protected form at one or more of the remaining (not previously protected) carboxyl, amino, hydroxy or other reactive groups. The protecting groups may be any of those known in the art. Examples of nitrogen and oxygen protecting groups are set forth in T.W. Greene, Protecting Groups in Organic Synthesis, Wiley, New York (1981); J.F.W. McOmie, ed., Protective Groups in Organic Chemistry, Plenum Press (1973); and J. Fuhihop and G. Benzlin, Organic Synthesis, Verlag Chemie (1983). Included among the nitrogen protective groups are tert-butoxycarbonyl (BOC), benzyloxycarbonyl, acetyl, allyl, phthalyl, benzyl, benzoyl, trityl, and the like. Included among the ketone protective groups is 1,3-dioxalane. The present invention provides for compounds of formula I or pharmacologically acceptable salts and/or hydrates thereof. Pharmacologically acceptable salts refers to those salts which would be readily apparent to a manufacturing pharmaceutical chemist to be equivalent to the parent compound in properties such as formulation, stability, patient acceptance and bipavail- ablility. Examples of salts of the compounds of the present invention include acidic salts, such as sodium and potassium salts of the compounds of formula I, and basic salts, such as the hydrochloride salt of the compounds of foπnula I, wherein the R substituents contain a basic moiety. The compounds of the present invention are useful for treating patients infected with human immunodeficiency virus (HIV) which results in acquired immunodeficiency syndrome (AIDS) and related diseases. For this indication, these compounds may be administered by oral, intranasal, transdermal, subcutaneous and parenteral (including intramuscular and intravenous) routes in doses of 0.1 mg to 100 mg/kg of body weight per day. Those skilled in the art would know how to formulate the compounds of this invention, using pharmaceutically acceptable carriers, into appropriate pharmaceutical dosage forms. Examples of the dosage forms include oral formulations, such as tablets or capsules, or parenteral formulations, such as sterile solutions. When the compounds in this invention are administered orally, an effective amount is from about 0.1 mg to 100 mg per kg of body weight per day. Either solid or fluid dosage forms can be prepared for oral administration. Solid compositions are prepared by mixing the compounds of this invention with conventional ingredients such as talc, magnesium stearate, dicalcium phosphate, magnesium aluminum silicate, calcium sulfate, starch, lactose, acacia, methyl cellulose, or functionally similar pharmaceutical diluents and carriers. Capsules are prepared by mixing the compounds of this invention with an inert pharmaceutical diluent or carrier and placing the mixtare into an appropriately sized hard gelatin capsule. Soft gelatin capsules are prepared by machine encapsulation of a slurry of the compounds of this invention with an acceptable inert oil such as vegetable oil or light liquid petrolatum. Syraps are prepared by dissolving the compounds of this invention in an aqueous vehicle and adding sugar, aromatic flavoring agents and preservatives. Elixirs are prepared using a hydroalcoholic vehicle such as ethanol, suitable sweeteners such as sugar or saccharin and an aromatic flavoring agent. Suspensions are prepared with an aqueous vehicle and a suspending agent such as acacia, traga- canth, or methyl cellulose. When the compounds of this invention are administered parenterally, they can be given by injection or by intravenous infusion. An effective amount is from about 0.1 mg to 100 mg per kg of body weight per day. Parenteral solutions are prepared by dissolving the compounds of this invention in aqueous vehicle and filter sterilizing the solution before placing in a suitable sealable vial or ampule. Parenteral suspensions are prepared in substantially the same way except a sterile suspension vehicle is used and the compounds of this invention are sterilized with ethylene oxide or suitable gas before it is suspended in the vehicle. The exact route of administration, dose, or frequency of administration would be readily determined by those skilled in the art and is dependant on the age, weight, general physical condition, or other clinical symptoms specific to the patient to be treated. Patients to be treated would be those individuals: 1) infected with one or more than one strain of a human immunodeficiency virus as determined by the presence of either measurable viral antibody or antigen in the serum and 2) having either an asymptomatic HIV infection or a symptomatic AIDS defining infection such as i) disseminated histoplasmosis, ii) isosporiasis, iii) bronchial and pulmonary candidiasis including pneumocystis pneumonia, iv) non-Hodgkin's lymphoma, or v) Kaposi's sarcoma and being less than sixty years old; or having an absolute CD4+ lymphocyte count of less than 500/mm 3 in the peripheral blood. Treatment would consist of maintaining an inhibitory level of the compounds of this invention in the patient at all times and would continue until the occurrence of a second symptomatic AIDS defining infection indicates alternate therapy is needed. The HIV protease utility of representative compounds of the present invention has been demonstrated in the biological test described below: IN VITRO HIV PROTEASE INHIBITORY ASSAY The HIV protease screening assay is based on a fluorescentiy labeled substrate which can be resolved from nonlabeled cleavage product using avidin-polystyrene particles, 0.7-0.9 μm. The substrate is biotinylated at the amino terminal arginine and fluorescentiy labeled with fluorescein isothiocynate (MIC) at the carboxyl terminal lysine. This assay has been employed to detect novel, nonpeptidic inhibitors of HIV-1 protease. Substrate (20 μl of 0.2 μM), sample (10 μl of desired concentraion), and enzyme (10 μl of 0.1 μM). are added to a 96 well pandex plate. The assay is ran in 0.1 M sodium acetate buffer at pH 5.5 in the presence of 1.0 M sodium chloride and 0.05% NP-40 and incubated in the dark for one hour at room temperatare. Avidin coated polystyrene beads {40 μl of 0.1% (w/v)} are added and the incubation is continued in the dark for an additional half hour. The labeled cleavage product is separated from the unreacted substrate via filtration and is read on the Idexx Screen Machine. The data are analyzed by appropriate computer algorithms to ascertain percent inhibition values. The % inhibition values, and in some instances IC 50 values or K j values, of representative compounds are listed in Tables I and II below. Several compounds of the present invention, such as 3-(alpha-ethylbenzyl)-6-(alpha- ethylphenethyl)-4-hydroxy-2H-pyran-2-one, were tested in known human cell lines, such as human T-cell lines, e.g., MT4 and H9, which were infected with HlV-l jjj g, and certain of these compounds were further tested in peripheral blood mononuclear cells (PBMC), which were infected with HIV-1 JRCSF (a clinical isolate). The compomids were found to inhibit retroviral replication. Surprisingly and unexpectedly, the compounds of the present invention have also been found to decrease the size and weight of the prostate gland in male mammals. This is particularly unexpected in view of the fact that these compounds are structurally quite unlike any known testosterone 5α-reductase inhibitor. Also, the compounds of this invention may have a number of other uses, as described more fully below. Thus, the present invention provides the use of compounds, such as 3-(α-Ethylbenzyl)-6- (α-ethylphenethy!)-4-hydroxy-2H-pyran-2-one, for preventing and treating androgen-dependent diseases, including the prevention and treatment of human and animal prostate lesions, such as benign prostatic hypertrophy and hyperplasia (nonneoplastic enlargements of the prostate) by, for example, maintaining and reducing the size of the prostate gland, and prostatic cancer in male mammals. Also, the present invention provides the use of these compounds to prevent and treat androgen-dependent skin diseases, such as alopecia, hirsutism, particularly female hirsutism, acne vulgaris and seborrhea, in mammals. By "preventing" is meant avoiding the occuπence of a disease. By "treating" is meant ameliorating or avoiding the effects of a disease. By "maintaining" is meant keeping in an existing state. By "mammals" is meant any warm-blooded vertebrate animal of the class Mammalia comprising humans and all other animals that nourish their young with milk secreted by mammary glands and have the skins usually more or less covered with hair. Especially included are human beings, dogs and rats. By "hypertrophy" is meant the enlargement or overgrowth of an organ or part due to an increase in size of its constituent cells. By "hyperplasia" is meant the abnormal multiplication or increase in the number of normal cells in normal arrangement in a tissue. Accordingly, the present invention is also concerned with providing a method of preventing or treating the androgen-dependent diseases of alopecia, hirsutism, acne vulgaris and seborrhea by topical administration, and a method of preventing or treating all of the above conditions as well as benign prostatic hypertrophy and prostate cancer, by topical or parenteral administration, of the compounds of the present invention. Thus, the present invention is concerned with providing suitable topical and parenteral pharmaceutical formulations for use in the novel methods of treatment of the present invention. The variety of therapeutic dosage forms for different modes of administration and their preparation are hereby incorporated by reference herein from the following: U.S. Patent 4,377,584, col. 10, line 52, through col. 11, line 31; U.S. Patent 4,760,071, col. 6, line 62, through col. 7, line 42; and U.S. Patent 5,017,568, col. 28, lines 3-39. The amount of the compound of foπnula I which is effective for the treatment of the above stated conditions ranges from 1 through 1000 mg/kg/day, with 50 through 400 mg/kg/day being preferred and 100 through 400 mg/kg/day being the most preferred. The exact therapeutic dosage form, mode and frequency of administration, and dosage would be readily determined by those skilled in the art and is dependent on the age, weight, general physical condition or other clinical symptoms specific to the patient, human and other mammals, to be treated. The following five (5) compounds of the present invention were tested in an in vitro testosterone 5α-reductase inhibitor assay: 3-(α-Ethylbenzyl)-6-(α-ethylphenethyl)-4-hydroxy- 2H-pyran-2-one; 6-(l -Benzyl -propyl)-3-(cyclopropyl-phenyl-methyl)-4-hydroxy-pyran-2-one; 3- (α-Ethylbenzyl)-6-(α-ethylbenzyl)-4-hydroxy-2H-pyran-2-one; 3-(α-Ethylbenzyl)-6-phenethyl-4- hydroxy-2H-pyran-2-one; 4-Hydroxy-3-( 1 -phenylpropyl)-6- [ 1 -[(tetrahydro-2H-pyran-3- yl)methyl] propyl] -2H-pyran-2-one. This assay is very similar to those described in the following references, except for the use of dog and rat prostates in place of human prostates: Proc. Natl. Acad. Sci. USA, Vol. 90: 5277-5281 (1993); J. Steroid. Biochem. Molec. Biol., Vol. 44, No. 2, pp. 121-131 (1993). All five (5) compounds had activity in this assay at a dose of at least 0.1 mM. Therefore, and without wishing to be limited to a specific mechanism of action, it was concluded that these compounds and other related compounds of the present invention would be useful for preventing or treating androgen-dependent diseases, such as those described above. The utility of representative compounds of the present invention has been demonstrated in the biological tests described below: 3-(α-Ethylbenzyl)-6-(α-ethylphenethyl)-4-hydroxy-2H-pyran-2-one was further tested in vivo in a four-week oral drug safety and toxicity study in beagle dogs, described in Example 208 below. It was found that, during the conduct of the postdosing evaluation of data from this study, there was a dose-related decrease in prostate size and weight in male dogs. Mean prostatic weights (n=3, 3 dogs in each of groups 1-5) are given in Table IV below. Light microscopic examination of high dose and control testes, adrenals and pitaitaries did not show drug-related changes. In a repeat study (groups 6 and 7, of 4 dogs each) the results of which are also given in Table IV, 2/4 high dose dogs had lower absolute and relative prostate weights than did the controls, but decreases were marked only in 1/4 dogs. As demonstrated in this in vivo test, the ability of 3-(α-Ethylbenzyl)-6-(α- ethylphenethyl)-4-hydroxy-2H-pyran-2-one to reduce the size and weight of the prostate gland, particularly without significant effects on testes and other endocrine glands, indicates that this compound and related compounds of the present invention would be useful to prevent or treat androgen-dependent diseases, such as those described above, especially benign prostatic hypertrophy and hyperplasia in male mammals.
