PREPARATION OF STEREOCHEMICALLY PURE OXIMES WITH MUSCARINIC ACTIVITY

Abstract: The instant invention is a selective formation of the Z-oxime and O-alkylation of 1-azabicyclo-(2.2.1)heptan-3-one and 1-azabicyclo(2.2.2)heptan-3-one oximes (I) to produce compounds with muscarinic activity. The process is capable of scale-up for industrial purposes as it provides better yields and ease of preparation. Intermediates are also described.

Description: PREPARATION OF STEREOCHEMICALLY PURE OXIMES WITH MUSCARINIC ACTIVITY BACKGROUND OF THE INVENTION Disorders of cognition are generally characterized by symptoms of forgetfulness, confusion, memory loss, attentional deficits, and/or, in some cases, affective disturbances. These symptoms may arise as a result of the general aging process and/or from organic brain disease, cerebrovascular disease, head injury, or developmental or genetic defects. The general decrease in cognitive function which accompanies the aging process is well accepted. The same phenomenon has been observed and documented in many lower mammals, including those routinely employed in pharmacological testing programs for screening and predicting usefulness for particular drugs in higher animals, including humans. Although disorders of cognition often accompany the general aging process, presenile and senile primary degenerative dementia are the most common accepted causes of mental deterioration in the elderly. It has been estimated that at least 10 percent of persons over 60 years of age will eventually suffer severe mental deterioration. A much larger number will experience cognitive decline of sufficient severity to impede their activities. Many of the symptoms of cognitive disorders, especially impaired memory, are associated with decreased acetylcholine synthesis and the impairment of cholinoreceptive neurons. In the hippocampus and cerebral cortex of patients suffering from primary degenerative dementia, for example, the level of the enzy e choline acetyltransferase (CAT) can be reduced by as much as 90% (see Davies, et al., The Lancet 1976;2:1403; Perry, et al., J. Neurol. Sci. 1977;34:247-265; and White, et al., The Lancet 1977;1:668-670). Since CAT catalyzes the synthesis of acetylcholine from its precursors choline and acetyl coenzyme A, the loss of CAT reflects the loss of cholinergic, or acetylcholine-releasing, nerve endings in the hippocampus and cerebral cortex. There is abundant evidence that cholinergic terminals in the hippocampus are critically important for memory formation. The cholinergic hypothesis suggests that drugs which restore acetylcholine levels or which mimic the action of acetylcholine (i.e., are cholinomimetic) are effective in correcting this deficit in neurotransmitter chemical and provide treatment of the memory impairment symptom of cerebral insufficiency. Considerable biochemical, pharmacological, and electrophysiological evidence supports the hypothesis that deficits in the cholinergic system underlie geriatric cognitive dysfunction (see Peterson C, Gibson GE, Neurobiol. Aging 1983;4:25-30). Aged humans and nonhu an primates with decreased cognition show improved memory when they are treated, for example, with acetylcholinesterase inhibitors such as physostigmine. These agents increase the available supply of synaptic acetylcholine by inhibiting its hydrolysis. Aminopyridines such as 3, 4-diaminopyridine ameliorate age-related cognitive deficits by increasing the release of acetylcholine from presynaptic nerve terminals, thus increasing synaptic acetylcholine (see Davis HP, et al., Exp. Aging Res. 1983;9:211-214) . It has been known for some time that the natural alkaloid, muscarine, has the ability to act relatively selectively at autonomic effector cells to produce qualitatively the same effects as acetylcholine. Two alkaloids, pilocarpine and arecoline (the methyl ester of 1,2,5, 6-tetrahydro- l-methyl-3-pyridinecarboxylic acid) , have the same principal sites of action as muscarine and acetylcholine and are thus classified as having "muscarinic" action. Although these naturally occurring alkaloids are of great value as pharmacological tools, present clinical use is largely restricted to the use of pilocarpine as a miotic agent. Recently it has been demonstrated that arecoline is effective in ameliorating some of the symptoms of cognitive disorders in patients clinically diagnosed as having presenile primary degenerative dementia. Significant improvement was observed in a test of picture recognition after administration of arecoline to patients in a double-blind study (see Christie, et al., Brit. J. Psychiatry ' 1981;138: 46-50) . The use of cholinomimetic agents in multiple clinical trials has documented both the potential therapeutic utility of cholinergic agents and the high incidence of unwanted side effects (see Hollander E, et al., Brit. Med. Bull. 1986;42:97- 100) . Many of these unwanted side effects result from the nonselective stimulation of cholinergic receptors (of the muscarinic type) located throughout the body. Muscarinic receptors have been classified pharmacologically and at the molecular level into several subtypes (see Bonner T, Trends Pharmacol. Sci. 1989; (Suppl. on Subtypes of Muscarinic Receptors IV):11-15). The receptors responsible for the central cognition-enhancing effects of muscarinic cholinomimetic agents are generally defined as M 1 (pharmacological definition) or ml (molecular definition) . Activation of peripheral M 2 and M 3 (or m2 and m3) receptors is thought to be responsible for the unwanted side effects of the currently available muscarinic agents (e.g., sweating, diarrhea, cramps, excessive salivation, etc) . Thus, selective M 1 (or ml) muscarinic agonists hold the best promise for selective improvement of cognitive function without the occurrence of unwanted side effects. United States Patent Number 5,306,718 covers final products prepared by the process of the instant invention.

SUMMARY OF THE INVENTION The instant invention is an alkylation process for the preparation of compounds of Formula I wherein R, R x , and n are as described below. DETAILED DESCRIPTION The azabicyclo[2.2.1]heptan-3-one oxime and azabicyclo[2.2.2] octan-3-one oxime compounds of Formula I can exist in two possible geometric forms known as E- and Z-. The pharmacological activity resides in the Z-isomers (United States Patent Number 5,306,718). The compounds have proved to be hard to separate on a small scale and not possible to separate on a large scale. The mixtures are partially separated by medium pressure chromatography. The low yield and the difficulty of separation were problems in the preparation of the final products. Unexpectedly, the instant process has overcome these problems and the process is expected to find utility in manufacturing plants on a larger scale. Only two steps are required and a good yield is produced.

In the process of the instant invention, in Step (a) the alcohol solvent is of sufficient dilution to keep reactants and products in solution. The alcohol solvent is, for example, methanol or ethanol, in a concentration equal to or lower than 0.4 M. The Step (d) of the process of the invention concerns alkylating the oximes in the presence of a basic amine carried out without destroying the stereochemistry of the oxime. The compounds of the present invention exist in the Z-isomeric form of the oxime, see below, and enantiomeric forms thereof. Moreover, in those compounds in which there is a double bond in a carbon chain, both the Z and E forms of the olefins are included in the present invention. In the compounds depicted by Formula I, the various substituents are further described as follows. Illustrative examples of straight or branched lower alkyl having from 1 to 4 carbon atoms or from 1 to 6 carbon atoms included methyl, ethyl, n-propyl, isopropyl, n-butyl, tert-butyl, n-pentyl, n-hexyl. Illustrative of lower alkoxy groups having from 1 to 4 carbon atoms are methoxy, ethoxy, and n-propoxy.. Illustrative examples of a saturated straight or branched hydrocarbon chain having from 1 to 20 carbon atoms include n-octyl, n-heptyl, dodecyl, tetradecyl, heptadecyl, etc, and all the illustrative examples of straight or branched lower alkyl groups having from 1 to 6 carbon atoms set forth above. Illustrative examples of straight or branched unsaturated hydrocarbon chains which contain from 1 to 4 unsaturations which are double or triple bonds are ethenyl, 2, 4-pentadienyl, 1, -pentadienyl, 2,4-pentadiynyl, 1,4-pentadiynyl, 2-penten-4-ynyl, 2-pentyn-4-enyl, 2-propenyl, 3-butenyl, 1-methyl- 2-propenyl, 2-pentenyl, 2-octenyl, 5-nonenyl, 4-undecenyl, 2-ethyl-3-butenyl, 4-hexenyl, 9, 12-octadienyl, hexadecenyl, ethynyl, 2-propynyl, l-methyl-2-propynyl, l-ethyl-2-propynyl, 1-methyl- 3-butynyl, 3-butynyl, or 4-pentynyl. Illustrative examples of cycloalkyl groups having from 3 to 6 carbon atoms are cyclopropyl, cyclobutyl, and cyclohexyl. Pharmaceutically acceptable acid addition salts of the compounds of Formulas I and V are illustratively hydrochloric, sulfuric, phosphoric, acetic, benzoic, citric, malonic, salicylic, malic, fumaric, oxalic, succinic, tartaric, lactic, gluconic, ascorbic, aleic, aspartic, benzenesulfonic, methane and ethanesulfonic, hydroxymethane- and hydroxyethanesulfonic (see, for example, "Pharmaceutical Salts," J. Pharm. Sci. 1977;66(1) :1-19) . Leaving groups include but are not limited to halogens and arylsulfonyloxy groups. Inert solvents include but are not limited to N,N-dimethylformamide, tetrahydrofuran, and toluene. The compounds prepared by the methodology of the present invention are centrally acting muscarinic agents and are thus useful as analgesic agents for the treatment of pain in mammals including man, as sleep aids, and as agents for treating the symptoms of senile dementia, Alzheimer's disease, Huntington's chorea, tardive dyskinesia, hyperkinesia, mania, or similar conditions characterized by decreased cerebral acetylcholine production or release, or conditions that respond favorably to central cholinergic stimulation. In therapeutic use as agents for treating pain or for treating cerebral insufficiency, the compounds utilized in the pharmaceutical method of this invention are administered to the patient at dosage levels of from 0.07 to 700 mg per day. For a normal human adult of approximately 70 kg of body weight, this translates into a dosage of from 0.01 to 100 mg/kg of body weight per day. The specific dosages employed, however, may be varied depending upon the requirements of the patient, the severity of the condition being treated, and the activity of the compound being employed. The determination of optimum dosages for a particular situation is within the skill of the art. For preparing pharmaceutical compositions from the compounds of this invention, inert, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, dispersible granules, capsules, cachets, and suppositories. A solid carrier can be one or more substances which may also act is diluents, flavoring agents, solubilizers, lubricants, suspending agents, binders, or tablet disintegrating agents; it can also be an encapsulating material. In powders, the carrier is a finely divided solid which is in a mixture with the finely divided active component. In tablets, the active compound is mixed with the carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired. For preparing suppositories, a low-melting wax such as a mixture of fatty acid glycerides and cocoa butter is first melted, and the active ingredient is dispersed therein by, for example, stirring. The molten homogeneous mixture is then poured into convenient sized molds and allowed to cool and solidify. Powders and tablets preferably contain between about 5% to about 70% by weight of the active ingredient. Suitable carriers are magnesium carbonate, magnesium stearate, talc, lactose, sugar, pectin, dextrin, starch, tragacanth, methyl cellulose, sodium carboxymethyl cellulose, a low-melting wax, cocoa butter, and the like. The term "preparation" is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component (with or without other carriers) is surrounded by a carrier, which is thus in association with it. In a similar manner, cachets are also included. Tablets, powders, cachets, and capsules can be used as solid dosage forms suitable for oral administration. Liquid form preparations include solutions suitable for oral or parenteral administration, or suspensions, and emulsions suitable for oral administration. Sterile water solutions of the active component or sterile solutions of the active component in solvents comprising water, ethanol, or propylene glycol may be mentioned as examples of liquid preparations suitable for parenteral administration. Sterile solutions may be prepared by dissolving the active component in the desired solvent system, and then passing the resulting solution through a membrane filter to sterilize it or, alternatively, by dissolving the sterile compound in a previously sterilized solvent under sterile conditions. Aqueous solutions for oral administration can be prepared by dissolving the active compound in water and adding suitable flavorants, coloring agents, stabilizers, and thickening agents as desired. Aqueous suspensions for oral use can be made by dispersing the finely divided active component in water together with a viscous material such as natural or synthetic gums, resins, methyl cellulose, sodium carboxymethyl cellulose, and other suspending agents known to the pharmaceutical formulation art.
