Description: LEUKOTRIENE B/, ANALOGS BACKGROUND OF THE INVENTION Metabolites of arachidonic acid constitute a class of important biological compounds. Members of this class include prostaglandins, prostacyclins, thromboxanes, and leukotrienes. The leukotrienes are recent additions to this family of biologi¬ cally important compounds. The leukotrienes are unsaturated fatty acid compounds derived from arachidonic acid by the action of lipoxygenase. Pioneering work in the isolation and identification of leukotrienes was reported at the Fourth International Prostaglandin Conference in 1979 by Samuelsson, et al., Leukotrienes: A New Group of Biologically Active Compounds, Advances in Prostaglandin and Thromboxane Research. Vol. 6, 1-18, (1980). Early synthetic work in the field was presented at the same conference by Corey, et al., Recent Studies on the Chemical Synthesis of Eicosanoids, Advances in Prostaglandin and Thromboxane Research. Vol. 6, 19-25, (1980). The leukotrienes constitute a general biological control system based on the precursor molecule arachidonic acid. Arachidonic acid is normally stored in biological membrane structures and can be released through activation of a hydrolytic system by a variety of stimuli. Depending on the availability of active enzymes in the stimulated cell, arachidonic acid transforms into one or several biologically active compounds. A variety of stimuli can thus be converted into a multitude of compounds that can regulate or mediate various cell functions. The new knowledge about this system suggests new pos¬ sibilities for the development of novel and more specific therapeutic agents, particularly in diseases related to immediate hypersen- sitivity reactions and inflammation. Such drugs might be based on antagonism of end products or inhibition of enzymes involved in the generation and further transformation of key intermediates, Samuels¬ son, Leukotrienes: Mediators of Immediate Hypersensitivity Reactions and inflammation, Science, Vol. 220, 568-575, (1983). Continuing work has shown the leukotrienes are important in the cellular regulation of diverse functions. LTB4, itself, stimulates aggregation and degranulation of human neutrophils, promotes chemo- taxis and chemokinesis of leukocytes, mediates lysosomal enzyme release and superoxide generation and constricts respiratory smooth muscle through an indirect mechanism involving stimulation of the release of cycloxygenase products. LTB4 is implicated in cystic fibrosis, asthma, adult respiratory distress syndrome, cutaneous allergic reactions, spondyloarthritis, rheumatoid arthritis, gout and inflammatory bowel disease because elevated concentrations of LTB4 have been found in sputum, lung edema fluid, epidermis, skin chamber fluid, synovial fluid and mucosa, Goetzl, et al. , Journal of Clinical Immunology, 82, (1984). The known effects of LTB4 indicate agonists or antagonists would be useful in many physiological conditions. For example, an LTB4 antagonist would be useful in the treatment of Inflammatory conditions where it is desirable to prevent migration of polymorphonuclear leukocytes to the inflammatory site. An LTB4 antagonist would also be useful In the treatment of respiratory diseases associated with hypersensitivity because the leukotrienes are potent constrictors of human bronchi, Dahlen, Nature, Vol. 288, 484, (1980). As noted, LTB4 is found in the sputum of cystic fibrosis patients, Cromwell, et al., The Lancet, July 25, 164-165, (1981) , suggesting the leukotrienes contribute to the rate of mucous secretions in the human respiratory tract. The excessive production of mucus, however, is a symptom of many pulmonary diseases. For example, In chronic bronchitis the flow of mucus may increase up to four times the normal rate. The inability of the patient to deal with this hyper-production causes conditions such as chronic bron¬ chitis, asthma, and cystic fibrosis. The role of leukotrienes as agonists in immediate hypersen- sitivity and other pathological conditions has led to research into inhibitors of leukotriene biosynthesis and leukotriene antagonists, Corey, et al., Tetrahedron Letters, 4243, (1980). Receptors for LTB4 have been characterized in human neutrophils and HL-60 cells. Although many compounds are known which interfere with the biosynthe- sis of LTB4, relatively few agents have been prepared which directly block its pharmacological effects. LTB4 diacetate has been reported to competitively inhibit chemotactic response of equimolar concentra¬ tions of LTB4. The corresponding dimethylamide of LTB4 is reported to inhibit neutrophil degranulation induced by LTB4 at concentrations where the agent has no appreciable agonist activity.

DETAILED DESCRIPTION OF INVENTION The compounds of the present invention will be named herein using the Chemical Abstracts numbering system (see Naming and Indexing of Chemical Substances for Chemical Abstracts during the Ninth Collective Period (1972-1976), a reprint of section IV from the Volume 76 Index Guide.) For a discussion of leukotriene nomencla¬ ture, see Samuelsson, et al. , Prostaglandins. Vol. 19, 645 (1980). The use of the symbol, ~, in the formulas represents -CH CH -, cis or trans -CH-CH- , or a mixture of cis and trans -CH-CH- and the symbol, «, in the formulas represents -CH 2 CH 2 -, cis or trans -CH-CH-, a mixture of cis and trans -CH-CH-, or -C=C-. Stereochemistry is represented in the formulas according to the following conventions: When a formula is written in its extended linear form, substituents below the plane of the aromatic ring are designated α and are represented by broken line attachments. Substituents above the plane of the aromatic ring are designated β and are represented by heavy solid line attachments. Substituents either below or above the plane of the aromatic ring and/or mixtures of a and β are represented by wavy line attachments. If no stereo¬ chemistry is Indicated, the configuration of the substituent is a , β or a mixture of and β . The compounds of this invention each have several centers of asymmetry. Preparation of these compounds can give, therefore, optically pure compounds (a single enantiomer) , optically inactive compounds (equal numbers of both enantiomers) , a partially enriched mixture (unequal numbers of both enantiomers) or a mixture of _ g _ diastereomers (more than 1 pair of enantiomers) . The formulas used herein are intended to represent all possible diastereomers. A formula representing a single enantiomer will be indicated by the prefix; (opt. act.). A racemic mixture will be indicated by the prefix; (+) . Generic substituents bonded to carbon are designated as R^, where I is an integer. Generic substituents bonded to atoms other than carbon are designated L j _, where i is an integer. Hydroxyl protecting groups are designated Lp, when Lp is not hydrogen. The carbon atom content of various hydrocarbon containing groups is indicated by a prefix designating the minimum and maximum number of carbon atoms in the moiety. For example, in defining the moiety, -COL5, wherein L5 is (C -C ) alkyl means L5 can be an alkyl group having from 1 to 12 carbon atoms. Additionally, any moiety so defined includes straight chain or branched chain groups. Thus, (0 - C 2 ) alkyl as set forth above includes straight or branched chain alkyl groups having from 1 to 12 carbon atoms. Examples of (C -C ) alkyl are methyl, ethyl, propyl, isopropyl, isobutyl, tert-butyl, isopentyl, neopentyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, and isomeric forms thereof.

When the ester form is used, the ester is any of those within the above definition of L5. However, It is preferred that the ester be alkyl of 1 to 12 carbon atoms, inc3_usive. Of the alkyl esters, methyl and ethyl are espe¬ cially preferred for optimum absorption of the compound by the body or experimental animal system, and straight-chain octyl, nonyl, decyl, undecyl, and dodecyl are especially preferred for prolonged activity . Pharmacologically acceptable salts of the novel compounds for the purposes described above are those with pharmacologically acceptable metal cations, ammonia, amine cations, or quaternary ammonium cations. Illustrative pharmacologically acceptable cations include the following representative examples. Especially preferred metal cations are those derived from the alkali metals, e.g., lithium, sodium, and potassium, and from the alkaline earth metals, e.g., magnesium and calcium, although cationic forms of other metals, e.g., aluminum, zinc, and iron, are within the scope of this invention. Pharmacologically acceptable amine cations are those derived from primary, secondary, and tertiary amines.

The acid addition salts of the compounds provided by this _ g _ invention are, for example, the hydrochlorides, hydrobromides, hydroiodides, sulfates, phosphates, cyclohexanesulfamates, methane- sulfonates r ethanesulfonates, benzenesulfonates, or toluenesulfonates prepared by reacting the appropriate compound with the stolchiometric amount of the acid corresponding to the pharmacologically acceptable acid addition salt. The novel LTB4 analogs disclosed herein produce a multiplicity of biological responses, rendering these compounds useful for a variety of pharmacological purposes. In particular, the biological responses include bronchodilation, nasal decongestion, peripheral vascular circulatory improvement, skin disease and inflammation reduction. Accordingly, the novel LTB4 analogs of the present invention are used as agents in the study, prevention, control, and treatment of diseases and other undesirable physiological conditions in mammals, particularly humans. The compounds of this invention affect smooth muscle contrac¬ tions and cellular secretions making these compounds useful as bronchodilators or as inhibitors of cellular mediators, released from cells activated by an antigen-antibody complex, which produce undesirable physiological responses. Use of these compounds controls spasm and facilitate breathing in conditions such as bronchial asthma, bronchitis, bronchiectasis, pneumonia and emphysema. The effect of the compounds of this invention on smooth muscle contraction were demonstrated in a standard laboratory test. Iso¬ lated prepared strips of guinea pig lung parenchyma were exposed to compounds of this invention. Certain compounds of this invention behaved as agonists because the parenchyma strips were desensitized by subsequent challenges with LTB4 but were not desensitized by sub- sequent challenges of histamine. Other compounds of this invention behaved as antagonists of myotropic activity of LTB4 at concentra¬ tions less than concentrations needed for agonist behavior. The novel LTB4 analogs herein are useful in mammals, including man, as nasal decongestants and are used for this purpose in a topical application dose range of about 10 μg to about 10 mg per ml of a pharmacologically suitable liquid vehicle or as an aerosol spray. These compounds are also useful In treating peripheral vascular disease in humans. The term peripheral vascular disease as used herein means disease of any of the blood vessels outside of the heart and disease of the lymph vessels, for example, frostbite, ischemic cerebrovascular . disease, artheriovenous fistulas, ischemic leg ulcers, phlebitis, venous insufficiency, gangrene, hepatorenal syndrome, ductus arteriosus, non-obstructive mesenteric ischemia, arteritis, lymphangitis and the like. These examples are included to be illustrative and should not be construed as limiting the term vascular disease. For these conditions the compounds of this invention are administered orally or parenterally by injection or infusion directly into a vein or artery, intravenous or intraarterial injections being preferred. The dosages of these compounds are in the range of 0.01-1.0 μg/kg of body weight administered by infusions at an hourly rate or by injection on a daily basis, the exact dose depending on the age, weight and condition of the patient and on the frequency and route of administration. Corresponding oral doses are in the range 0.05-50 mg every 2 hours, up to a maximum of 6 doses daily. Treatment is continued for 1 to 5 days, although 3 days is ordinarily sufficient to assure long-lasting therapeutic action. In the event that systemic or side effects are observed the dosage is lowered below the threshold at which such systemic or side effects are observed. The novel LTB4 analogs of this invention are useful for treating proliferating skin diseases of man and domesticated animals, includ- ing psoriasis, atopic dermatitis, non-specific dermatitis, primary irritant contact dermatitis, allergic contact dermitits, basal and squamous cell carcinomas of the skin, lamellar ichthyosis, epider- molytic hyperkeratosis, premalignant sun-induced keratosis, non- malignant keratosis, acne, and seborrheic dermatitis in humans and atopic dermatitis and mange in domestic animals. These compounds alleviate the symptoms of these proliferative skin diseases: psoriasis, for example, being alleviated when scale-free psoriasis lesion is noticeably decreased in thickness or noticeably, but incompletely cleared, or completely cleared. For these purposes, these compounds are applied topically as compositions including a suitable pharmaceutical carrier, for example as an ointment, lotion, paste, jelly, spray, or aerosol, using topical bases such as petrolatum, lanolin, polyethylene glycols, and alcohols. These compounds, as the active Ingredients; constitute from about 0.1% to about 15% by weight of the composition, preferably from about 0.5% to about 2% by weight of composition. In addition to topical administration, injection may be used, as intradermall , intra- or peri-lesionally, or subcutaneously, using appropriate sterile saline compositions. The LTB4 analogs of this invention are useful as antiinflam¬ matory agents for inhibiting chronic inflammation in mammals includ¬ ing the swelling and other unpleasant effects thereof using methods of treatment and dosages generally used for similar therapeutic agents known in the art. The effect of the compounds of this invention to inhibit LTB4 binding to human neutrophil membranes were demonstrated in a standard laboratory test. The ability of compounds of this invention at varying concentrations to competitively bind to the LTB4 receptor in human neutrophil membranes in the presence of a known concentration of LTB4 were measured. The tests also demonstrated the compounds effected neutrophil aggregation. Hammerstrom, et al. , Science Vol. 197, 994-996 (1977) notes the role of the leukotrienes including LTB4 in psoriasis. Doig, et al. , Prostaglandins, Vol. 20, 1007-1019 (1980) and Lin, et al. , J. Clin. Invest., Vol 70, 1058 (1982) discloses the leukotrienes including LTB4 block platelet thrombus formation. Dawson, et al., SRS-A and Leukotrienes, 219-226, Wiley and Sons (1981) notes the leukotrienes including LTB4 inhibitors block neutrophil "recruitment" during inflammatory diseases such as arthritis. The leukotrienes including LTB4, have been implicated in essential hypertension, Chand, et al. , Mlcrocirculation, 111-123 (1981), and gout, Rae, et al. , Lancet, 1122-1124 (Nov. 20, 1982), indicating that the compounds disclosed and claimed herein are useful In treating these conditions as well. Further, neutrophil depletion, such as that induced leukotrienes including LTB4, cause a significant decrease in infarct size following circumflex artery occlusion, Ro son, et al. , Circulation, 85 (1982) . Thus, these compounds may be useful in the protection of the myocardium following infarct. The compounds of the present invention are also useful for the prevention or treatment of deep vein thrombosis (DVT) . DVT is the thrombosis (clot formation) of the lower limb deep veins (deeply situated veins). Such thrombosis is frequently a result of major surgery, massive trauma, myocardial infarction, neoplasia, or pregnancy. The term "deep vein thrombosis" or "DVT" encompasses the thrombosis resulting from these or any other causes. The term- "prevention" means the total or partial avoidance of clot formation in the deep veins of a mammal. Any convenient route of administration is employed. Oral formulation and oral administration are preferred route for use in humans although parenteral; intravenous, intraperitoneal, and in- tramuscular, administration can also be used. The dosage regimen for the compounds used to treat deep ' vein thrombosis will depend on a variety of factors, including the type, age, weight, sex, and medical condition of the mammal, and most importantly on the risks and probable consequences of deep vein thrombosis. It is within the skill of the attending physician or veterinarian to determine the risks of deep vein thrombosis, and to prescribe an effective amount of the leukotriene antagonist claimed herein. The dosage is in the range of about 0.01 to about 1 mg/kg/ minute by intravenous infusion, or about 0.1 to about 50 mg/kg/day by oral administration. Equivalent dosages for other routes of adminis¬ tration are also employed. The compounds of this invention are administered in ' a variety of dosage forms: orally in the form of tablets, capsules, or liquids; rectally in the form of suppositories; parenterally, subcutaneously, or intramuscularly, with intravenous administration being preferred in emergency situations; by Inhalation in the form of aerosols or solutions for nebulizers; or by insufflation in the form of powder. When treating conditions for which a dosage range is not specified above, doses in the range of about 0.01 to 50 mg per kg of body weight are used 1 to 4 times a day. The exact dose is determined by the age, weight, and condition of the patient or animal and on the frequency and route of administration. The compounds of this invention are effectively administered to human asthma patients by any convenient route such as oral irihala- tion, aerosol inhalation, parenterally, transdermally or topically. For administration by the oral inhalation route with convention¬ al nebulizers or by oxygen aerosolization it Is convenient to provide the active ingredient in dilute solution, preferably at concentra- tions of about 1 part by weight of medicament to about 100 to 200 parts by weight of total solution. Conventional additives such as, sodium chloride, sodium citrate, citric acid and sodium bisulfite, may be employed to stabilize these solutions or to provide isotonic media. For administration of the active ingredient in aerosol form for Inhalation therapy the composition as a self-propelled dosage unit can comprise the active ingredient; an inert propellant (such as a mixture of dichlorodlfluoromethane and dichlorotetrafluoroethane) ; a co-solvent (such as ethanol); flavoring materials and stabilizers. Instead of a co-solvent, a dispensing agent such as oleyl alcohol could be used. A suitable means to employ the aerosol inhalation therapy technique is described in U.S. Pat. No. 2,868,691. For the treatment of asthma these compounds can be combined advantageously with other anti-asthmatic agents, such as sympathomi- metics (isoproterenol, phenylephedrine, ephedrine, etc.); xanthine derivatives (theophylline and aminophylline) and/or corticosteroids (ACTH and prednisolone) . The compounds of this invention are formulated into compositions for administration to humans and animals in unit dosage forms containing suitable quantities of the compound. Suitable administra¬ tions means include: tablets; capsules; pills; powders; granules; sterile parenteral solutions or suspensions;eye drops; oral solutions or suspensions, and oil in water and water in oil emulsions. For oral administration solid or fluid unit dosage forms can be prepared. For preparing solid compositions, the compounds of this invention are mixed with conventional ingredients such as talc, magnesium stearate, dicalcium phosphate, magnesium aluminum silicate, calcium sulfate, starch, lactose, acacia, methylcellulose, and/or functionally similar pharmaceutical diluents or carriers. Capsules are prepared by mixing the compound with an inert pharmaceutical diluent and filling the mixture into a hard gelatin capsule of appropriate size. Soft gelatin capsules are prepared by machine encapsulation of a slurry of the compound with an acceptable veget- able oil, light liquid petrolatum or other inert oil. For preparing fluid compositions, the compounds of this inven¬ tion are dissolved in an aqueous vehicle together with sugar, aromatic flavoring agents and preservatives to form a syrup. An elixir is prepared by using a hydroalcoholic (ethanol) vehicle with suitable sweeteners such as sugar and saccharin, together with an aromatic flavoring agent. Suspensions are prepared in an aqueous vehicle with the,aid of a suspending agent such as acacia, tragacan- th, or methylcellulose. For parenteral administration, fluid unit dosage forms are prepared utilizing the compound and a sterile vehicle, preferably water. The compounds of this invention, depending on the vehicle and concentration used, can be either suspended or dissolved in the vehicle. In preparing solutions, the compound is dissolved in a suitable vehicle, filtered, sterilized, loaded into a suitable vial or ampoule and sealed. Adjuvants such as a local anesthetic, preservative and buffering agents, can be dissolved in the vehicle. To enhance the stability, the composition can be frozen after loading into the vial and the vehicle removed. The dry lyophillzed powder is then sealed in the vial and an accompanying vial of water for injection is supplied to reconstitute the liquid prior to use. Parenteral suspensions are prepared in substantially the same manner except that the compound is suspended in the vehicle instead of being dissolved and sterilization cannot be accomplished by filtration. These compounds can be sterilized by exposure to ethylene oxide or an equivalent sterilizing gas before suspending in the sterile vehicle. A surfactant or wetting agent is included in the composition to facilitate uniform distribution of the compound. For inhalation, powders, solutions, or aerosols can be prepared. Powders are prepared by mixing a suitable pharmaceutically useful compound of this invention with a solid base compatible with lung tissue, preferably lactose. The powders are packaged in a device adapted to emit a measured amount of powder when inhaled through the mouth. Aqueous solutions are prepared by dissolving the appropriate compound of this invention in water, adding salt to provide an isotonic solution and buffering to a pH compatible with inhalation. The solutions are dispersed in a spray device or nebulizer and sprayed into the mouth while inhaling. Aerosols are prepared by dissolving the appropriate compound of this invention in water or ethanol, mixing with a volatile propellant and placing the composition in a pressurized container having a metering valve to release a predetermined amount of material. The volatile propellant employed is one which has a boiling point below 65 β F at atmospheric pressure. For use in compositions intended to produce aerosols for medicinal use, the propellant should be non-toxic. Among the suitable propellants which may be employed are the lower alkanes containing up to 5 carbon atoms, such as butane and pentane, or a lower alkyl chloride, such as methyl, ethyl or propyl chlorides. Other suitable propellants are fluorinated and fluorochlorinated lower alkanes or mixtures thereof, such as, dichlorodifluoromethane, dichlorotetrafluoroethane, trichloromono- fluoromethane, dichloromonofluoromethane, monochlorodifluoromethane, trlchlorotrifluoroethane, difluoroethane and monochlorotrifluor¬ omethane. The LTB4 analogs of this invention represented by formulas I and II are prepared by various procedures which are all generally known In the art. The preparation of the compounds this invention are outlined in the charts described below. Chart A outlines the preparation of some of the compounds of formula I, where Y is A-l to A-4, and the compounds of formula IV, where P is A-5 to A-8. The meta-substituted aromatic compound, A-I where A-l is A_F to AF4, is monolithiated by n-butyllithium and the anion is reacted with dimethylformamide in diethyl ether to give the haloaldehyde, A-II. The haloaldehyde reacts with a Wittig reagent, AW, formed by reacting a known carboxyphosphonium halide with known bases such as lithium (bis)crimethylsilylamide in THF, to give a mixture of cis and trans olefin acids, A-III. Wittig reagents defined by AW are commercially available or are prepared by known methods. Specific examples of Wittig reagents within the scope of this invention are disclosed in U.S. Pat. No. 3,776,941. To prepare the compounds of this invention where ^ and A taken together are a lactone, the mixture of olefin acids is lactonized with potassium iodide in the presence of potassium bicarbonate in THF/water to give the iodolactone, A-IV where E is Iodo. Alterna¬ tively, the mixture of olefin acids is . lactonized with N-phenyl- selenylphthalimide in the presence of camphorsulfonic acid in methylene chloride to give the selenolactone, A-IV where E is Se(CgH5 . The selenolactone and the iodolactone are reduced with tri-n-butyltin hydride in the presence of azo-(bis)isobutylnitrile in toluene to give the lactone, A-V. To prepare compounds of this invention where M^ and A taken together are a lactol, the lactone, A-V is reduced with sodium (bis)2-methoxyethoxy aluminum hydride in toluene at -20" to 0". To prepare compounds of this invention where M ] _ is hydroxy or a protected hydroxy and hydrogen, the lactone, A-V, is hydrolyzed to the hydroxy acid with aqueous sodium hydroxide in methanol to give the hydroxy acid, A-VI. The hydroxy group can be protected by procedures already described. To prepare compounds of this invention where ] _ is hydroxy or a protected hydroxy and methyl, the hydroxy acid, A-VI is oxidized to the ketone by known methods and then reacted with a methyl lithium or a methyl grignard reagent to give the desired methylated compound, A- VII. To prepare compounds of this invention where R5 is the epoxide, the iodolactone, A-IV where E is Iodo, reacts in the presence of potassium carbonate in methanol gives the epoxy ester, A-VIII. The epoxy ester, A-VIII, reacts with sodium cyanoborohydride in boron trifluoride etherate to open the epoxide giving compounds where ^ is hydroxy and hydrogen. The preparation of compounds of this invention is completed by adding the B-C^C-CH 2 C(M 2 )-C»C- side chain using a palladium-copper catalyzed cross coupling reaction, described by, K. Sonogashira, et al., Tetrahedron Letters, 4467 (1975) and S. Takahashi, et al., Synthesis, 627 (1980). Compounds A-III, A-V, A-VI, A-VII or A-VIII and B-C=C-CH C(M 2 )-C«CH react in the presence of (bis)triphenylphos- phine palladium dichloride and cuprous iodide in triethylamine at 50° to 70° for 3 to 6 hours to give the coupled compounds where B-C-C- CH 2 C(M 2 )-C=C- has replaced X-. The coupling reaction using A-III gives A-IX, A-V gives A-X, A-VIII gives A-XI. To prepare compounds of this invention where Z is -CH 2 0H, M^ is hydroxy, A-X is reduced with an excess of sodium (bis)2-methoxyethoxy aluminum hydride in toluene at -20° to 0 β . These reaction conditions also reduce any propargylic triple bonds to trans double bonds. A similar reduction of compounds A-IX and A-XI reduces the acid to the primary alcohol. The primary alcohol of the reduced compounds is selectively oxidized to the free carboxylic acid by reacting the compounds with elemental oxygen in the presence of platinum black in water/acetone. Alternatively, the preparation of the compounds of this inven¬ tion can be completed by a sequential process to replace X- with B- . Compound A-Il Is ketalized by known procedures and is reacted with commercially available monotrlmethylsilyl acetylene In the presence of (bis)triphenylphosphine palladium dichloride and cuprous iodide In diethylamine at 45" for 6 hours to give the trimethylsilyl alkyne, A-XII. Hydrolysis of the crimethylsilyl alkyne with potassium hydroxide in methanol/water or tetra-butyl- ammonium fluoride in THF at room temperature gives the alkyne which is deprotonated by IDA in THF at -78° and added B-C»C-CH 2 CH0 at -78° to give A-XIII. The procedures described for A-II are used following hydrolysis of the ketal to the aldehyde to give compounds of this invention where M 2 is hydroxy and hydrogen. Compound A-II can also be coupled to B-C~C-CH 2 C(M )-C»CH by procedures already described. To prepare compounds of this invention where M 2 is hydroxy or a protected hydroxy and methyl, A-XIII Is oxidized to the ketone by known methods and then reacted with a methyl lithium or a methyl grignard reagent to give the desired methylated compounds. To prepare compounds of this invention with cis double bonds, triple bonds are partially hydrogenated with known catalysts to give the cis stereochemistry. To prepare compounds of this invention with trans double bonds, propargylic triple bonds are reduced with sodium (bis)methoxyethoxy aluminum hydride in toluene at -20° to 0° to give the trans stereochemistry. Other cis or trans double bonds are pre¬ pared by known methods. When Z is C0 2 CH3, the methyl ester Is saponified in aqueous lithium or sodium hydroxide to give the acid. When Z is C0 2 CH3 or C02H, the acid or methyl ester Is reduced to the primary alcohol by reacting the compounds with an excess of lithium aluminum hydride in THF at room temperature. To prepare compounds of this invention where 5 is -CH(Rg)- C(M )-, epoxide A-VIII is opened with a known thiol compound in the presence of base. The sulfide resulting from the epoxide opening can be oxidized to the sulfoxide or the sulfone by known methods. When Z is CO2H and an alkyl or cycloalkyl ester is desired, esterification is accomplished by reacting the acid with an ap¬ propriate diazohydrocarbon. For example, diazomethane, diazoethane, diazobutane, l-diazo-2-ethylhexane, and diazodecane give the methyl, ethyl, butyl, and 2-ethylhexyl and decyl esters. Similarly, diazocy- clohexane gives the cyclohexyl ester. Esterification with diazo- hydrocarbons is carried out by mixing the acid with the diazohydro- carbon in a suitable inert solvent, preferably diethyl ether. After the esterification reaction is complete the solvent is removed by evaporation, and the ester is purified by conventional methods, preferably by chromatography. It is preferred that contact of the acid with the diazohydrocarbon be no longer than necessary to effect the desired esterification, preferably about 1 to 10 minutes, to avoid undesired side reactions. Diazohydrocarbons are known in the art or can be prepared by methods known in the art. See, for example, Organic Reactions, John Wiley and Sons, Inc., New York, NY, Vol. 8, pp. 389-394 (1954). An alternative method for preparing alkyl or cycloalkyl esters comprises transforming the acid to the corresponding substituted ammonium salt and reacting that salt with an alkyl iodide. Suitable alkyl iodides are methyl iodide, ethyl iodide, butyl iodide, isobutyl iodide, tert-butyl iodide, cyclopropyl iodide, or cyclopentyl iodide. The compounds of this invention prepared by the processes of this invention, in free acid form, are transformed to pharmacologi¬ cally acceptable salts by neutralization with appropriate amounts of the corresponding inorganic or organic base, examples of which corre¬ spond to the cations and amines listed hereinabove. These transform- ations are carried out by a variety of procedures known in the art to be generally useful for the preparation of inorganic, i.e., metal or ammonium salts. The choice of procedure depends in part upon the solubility characteristics of the particular salt to be prepared. In the case of the inorganic salts, it is usually suitable to dissolve an acid of this invention in water containing the stoichiometric amount of a hydroxide, carbonate, or bicarbonate corresponding to the inorganic salt desired. For example, use of sodium hydroxide, sodium carbonate, or sodium bicarbonate gives a solution of the sodium salt. Evaporation of the water or addition of a water-miscible solvent of moderate polarity, for example, a lower alkanol or a lower alkanone, gives the solid inorganic salt if that form is desired. To produce an amine salt, an acid of this invention is dissolved in a suitable solvent of either moderate or low polarity. Examples include: ethanol, acetone, ethyl acetate, diethyl ether and benzene. At least a stoichiometric amount of the amine corresponding to the desired cation is then added to that solution. If the resulting salt does not precipitate, it is usually obtained in solid form by evaporation. If the amine is relatively volatile, any excess can easily be removed by evaporation. It is preferred to use stoichio¬ metric amounts of the less volatile amines. Salts wherein the cation is quaternary ammonium are produced by mixing an acid of this Invention with the stoichiometric amount of the corresponding quaternary ammonium hydroxide in water solution, followed by evaporation of the water. The hydroxyl groups of the compounds of the present invention may be protected by various groups generally employed in the art if protection of the hydroxyl functions is desirable or necessary during the preparation of the compounds. Although any of the various pro¬ tecting groups known in the art may be employed, those preferred are tetrahydropyranyl (THP) and tert-butyldimethylsllyl. Particularly, THP is a preferred protecting group during the various reactions required to add the side chains and t-butyldimethylsilyl is a preferred group to employ during separation of the isomers. Of course it may be useful or desirable to utilize protecting groups which may be selectively hydrolyzed. As indicated hereinabove, Lp is hydrogen or a protecting group. Those protective groups within the scope of I— are any group which replaces an hydroxyl hydrogen, is not- reactive to the reagents used in subsequent transformations and is readily removed to regenerate the original hydroxyl group hydrogen. Many protective groups are known in the art. For reference see, E.J. Corey, Proceedings of the Robert A. Welch Foundation Conferences on Chemical Research, Organic Synthesis XII. 51-79 (1969). When the protecting group, Lp, is a tetrahydropyranyl or a tetrahydropyranyl ether derivative the protected hydroxy compounds are prepared by reacting of the hydroxyl containing compound with 2,3-dIhydropyr n in an inert solvent in the presence of an acid condensing agent such as p-toluenesulfonic acid or pyridine hydro- chloride. The dihydropyran Is used in large stoichiometric excess, preferably 4 to 100 times the stoichiometric amount. The reaction is normally complete in less than an hour at 20 β -50°C. When the protecting group, l , is silyl reagent, selective pro¬ tection is possible. Some silylating reagents are non-selective all hydroxyls of a molecule are silylated. Other silylating reagents are selective because, one or more hydroxyls are silylated without affect- ing other hydroxyl groups. Silyl groups include trlmethylsilyl, dimethylphenylsilyl, triphenylsilyl, t-butyldimeth lsilyl, or methyl- phenylbenzylsilyl. These silyl groups are known in the art. See, for example, Pierce, Sil lation of Organic Compounds. Pierce Chemical Company, Rockford, Illinois (1968). When silylated products are intended to be subjected to chromatographic purification, the use of silyl groups known to be unstable to chromatography (e.g., trlmethyl¬ silyl) should be avoided. When silyl groups are to be introduced selectively, silylating agents which are readily available and known to be useful in selective silylations are used. For example, t-but- yldimethylsilyl groups are used when selective introduction is required. When silyl groups are to be selectively hydrolyzed in the presence of other protective groups the use of silyl groups which are readily available and known to be easily hydrolyzed with tetra-n- butylammonium fluoride are used. A particularly useful silyl group for this purpose is t-butyldimethylsilyl. The protective groups as defined by Lp are generally removed by mild acidic hydrolysis. For example, by reaction with (1) hydro¬ chloric acid in methanol; (2) a mixture of acetic acid, water, and tetrahydrofuran, or (3) aqueous citric acid or aqueous phosphoric acid in tetrahydrofuran, at temperatures below 55 β C, hydrolysis of the blocking group is achieved. Lp may also be an acyl protective group. Methods known in the art are used to prepare acyl derivatives of hydroxy compounds. For example, benzoic acid reacts with the hydroxy compound in the pres- ence of a dehydrating agent, such as p-toluenesulfonyl chloride or dicyclohexylcarbodiimide to giv ethe acyl derivative. Alternatively, an acid anhydride such as benzoic anhydride, is used instead of the free acid. The preferred method to prepare acyl derivatives uses the appropriate acyl halide. For example, benzoyl chloride reacts with the hydroxy compound in the presence of a hydrogen chloride scaveng¬ er, such as, pyridine or triethylamine. The reaction is carried out under a variety of conditions, using procedures known in the art. The reaction occurs occurs at mild temperatures 0°-60 β C by contacting the reactants in excess pyridine or an inert solvent such as benzene, toluene, or chloroform. The acylating agent is used either in stoichiometric amount or in substantial stoichiometric amount or in substantial stoichiometric excess. The acyl protective groups are removed by deacylation. Alkali metal carbonate or hydroxide are employed effectively at ambient temperatures for this purpose. For example, potassium carbonate or hydroxide in aqueous methanol at about 25°C is used. Purification, isolation and separation of isomeric and di- astereomeric mixtures is achieved by well known means, including column chromatography.
