     FIELD OF INVENTION 
     The present invention is a class of oximes and amines which are muscarinic agonists, rendering them useful as pharmaceutical agents. More specifically, the compounds are azabicyclic and azacyclic oximes and amines. 
     BACKGROUND 
     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 ten 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 enzyme choline acetyltransferase (CAT) can be reduced by as much as 90%. (See Davies, et al, The Lancet, 1976 (Vol. 2) :1403; Perry, et al, J. Neurol. Sci., 34:247-265 (1977! ); and White, et al, The Lancet, 1977 (vol. 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 acetyicholine (i.e., are cholinomimetic) are effective in coterecting 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 C. Peterson and G. E. Gibson, Neurobiol. Aging, 4:25-30 (1983)). Aged humans and nonhuman 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 H. P. Davis, et al, Exp. Aging Rest, 9:211-214 (1983)). 
     It has been known for some time that the natural alkaloid, muscararine, 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-1-methyl-3-pyridinecarboxylic acid), have the same principal sites of action as muscarine and acetylcholine and are thus classified as having &#34;muscarinic&#34; 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 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, 138: 46-50 (1981)) .

     The free base forms of the compounds of this invention differ somewhat from their respective salt forms in such physical properties as melting point and solubility in polar solvents, but the salts are otherwise equivalent to their respective free acid or base forms for the purposes of the invention. 
     The starting materials represented by Formulas XI, XII, and XIII are known in the art or can be prepared by procedures generally known in the art. See, for example, J. Saunders, et al, J. Chem.

Also, the amines represented by NH 2  OR are commercially available or may be prepared by procedures generally known in the art. For example, the amines can be prepared by the Mitsunabu reaction by reacting a phthalimide with an appropriate alcohol and hydrolyzing the resultant intermediate using methylhydrazine.

     1-Methyl-4-piperidone (5 g, 44.2 mmol) and methoxyamine hydrochloride (3.69 g, 44.2 mmol) were taken into 25 mL of methanol and stirred at room temperature for 2 days. The reaction mixture was evaporated in vacuo to afford a solid residue. The residue was dissolved in water, made basic with solid potassium carbonate, and extracted with dichloromethane (3×100 mL) . The combined extracts were dried over anhydrous sodium sulfate and evaporated to give a clear, yellow liquid that was purified on silica gel, eluting with dichloromethane-methanol (95:5) to afford 2.55 g of the desired product. Treatment with ethereal hydrogen chloride gave the hydrochloride salt, 2.99 g, m.p. 145°-147° C.

     1-Azabicyclo[2.2.1]heptan-3-one (2 g, 18 mmol) and O-allylhydroxylamine hydrochloride hydrate (1.97 g, 18 mmol) were dissolved in 25 mL of methanol and stirred at room temperature for 18 hours. The reaction was evaporated in vacuo to give a viscous oil. The crude oil was dissolved in 50 mL of water, made basic with a saturated solution of potassium carbonate, and extracted with ether (3×100 mL). The combined extracts were dried over anhydrous sodium sulfate, and evaporated to give a clear, yellow liquid which was purified on silica gel, eluting with dichloromethane-methanol (10: 1). Isomer A, the less polar isomer, was isolated and converted to the oxalate salt to give 1.365 g, m.p. 130-°132° C.

     The compounds 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&#39;s disease, Huntington&#39;s chorea, tardive dyskinesia, hyperkinesia, mania, or similar conditions of cerebral insufficiency characterized by decreased cerebral acetylcholine production or release. 
     The biological activity of compounds of the present invention was evaluated using a number of tests. The activity of compounds of this invention as central muscarinic binding site agonists and antagonists was measured. In the RQNB screening assay, which is described more fully by Mark Watson, et al, J. Pharmacol. and Exp. Ther., 237(2):411 (1986), rat cerebral cortex tissue was treated with radiolabeled quinuclidinyl benzilate, a known muscarinic binding site antagonist. The concentrations of test compound required to inhibit of the binding of this muscarinic antagonist were then determined. 
     Similarly, in the RCMD screening assay, described more fully by T. W. rickroy, et al, 229(3):747 (1984), rat. cerebral cortex tissue was treated with radiolabeled cis-methyldioxolane, a known muscarinic binding site agonist. The concentrations of test compounds required to inhibit 50% of the binding of this muscarinic agonist were then determined. These values are reported as IC50 concentrations in Table 2 and demonstrate that the compounds of the present invention possess significant muscarinic activity.

     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 &#34;preparation&#34; 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. 
     Preferably, the pharmaceutical preparation is in unit dosage form. In such form, the preparation is divided into unit doses containing appropriate quantities of the active component. The unit dosage form can a packaged preparation, the package containing discrete quantities of the preparation, for example, packeted tablets, capsules, and powders in vials or ampoules. The unit dosage form can also be capsule, cachet, or tablet itself, or it can be the appropriate number of any of these packaged forms. ##STR80##
