Novel bicycloheptene derivatives

摘要

Novel bicycloheptene compounds of the formula: wherein A is C2-C4 alkylene; X and B are each ethylene or vinylene; R1 is hydrogen, C1-C8 alkyl, C4-C8 alkoxyalkyl, C5-C7 cycloalkyl, C5-C8 cycloalkylalkyl, aryl, C7-C10 arylalkyl, C7-C10 aryloxyalkyl; R2 is hydrogen, or C1-C4 alkyl; and Z is carboxyl, C2-C5 alkoxycarbonyl or C1-C5 carbamoyl, and its non-toxic salts, which are useful as antiulcers, gastric secretion inhibitors, central nervous system regulators, and labor inducing agents.
