Title: Novel heterocyclic compounds and pharmaceutical composition containing them
Abstract:The invention relates to the production of compounds of the general formula: ##STR1## wherein X is selected from the group consisting of oxygen, CH.sub.2 and CH radicals, and when X designates oxygen, R designates alkyl, isoalkyl, aralkyl, and substituted aralkyl groups and when X designates CH.sub.2 then R designates alkyl, phenyl or substituted phenyl group, and A-B is a single bond, and when X designates CH.sub.2, R designates alkyl, phenyl or substituted phenyl groups and A-B is a double bond; and physiologically acceptable salts of these, and pharmaceutical compositions containing the same as active ingredient.
Inventor(s): Cohen; Sasson (Tel-Aviv, IL), Fisher; Abraham (Holon, IL)
Assignee: The Purdue Frederick Company (Norwalk, CT)
Filing Date:Oct 23, 1978
Application Number:05/953,514
Claims:1. A process for the production of a salt of a compound of the formula: ##STR8## wherein X is oxygen, and wherein R is a radical selected from the group consisting of lower alkyl, cyclopentyl and cyclohexyl, which comprises reacting 2-methylenequinuclidin-3-one with the corresponding radical -substituted diloweralkylmalonate in the presence of sodium alkoxide to give the corresponding 3-oxoquinuclidin-2-yl) malonate, reducing the latter with sodium borohydride to the corresponding (3-hydroxyquinuclidin-2-yl malonate, and treating the latter with a concentrated mineral acid to obtain the desired product, a 4-radical-6-oxa-1-azatricyclo (4.2.2.0.sup.2,7) dodecan-5-one salt.

2. A process for the production of a salt of a compound of the formula: ##STR9## wherein X is oxygen and R is a radical selected from the group consisting of thienyl, phenyl, methylphenyl, methoxyphenyl, chlorophenyl, trifluromethylphenyl, aminophenyl, di-loweralkylaminophenyl and benzyl, which comprises reacting 2-methylene quinuclidin-3-one with the corresponding radical-substituted diloweralkylacetate in the presence of sodium alkoxide to give the corresponding (3-oxoquinuclidin-2-yl) acetate, reducing the latter with sodium borohydride to the corresponding (3-hydroxyquinuclidin-2-yl) acetate, and treating the latter with a concentrated mineral acid to obtain the desired product, a 4-radical-6-oxa-1-azatricyclo(4.2.2.0.sup.2.7) dodecan-5-one salt.
