Abstract
Novel bicycloheptene compounds of the formula: ##STR1## wherein A is C.sub.2 -C.sub.4 alkylene; X and B are each ethylene or vinylene; R.sub.1 is hydrogen, C.sub.1 -C.sub.8 alkyl, C.sub.4 -C.sub.8 alkoxyalkyl, C.sub.5 -C.sub.7 cycloalkyl, C.sub.5 -C.sub.8 cycloalkylalkyl, aryl, C.sub.7 -C.sub.10 arylalkyl, C.sub.7 -C.sub.10 aryloxyalkyl; R.sub.2 is hydrogen, or C.sub.1 -C.sub.4 alkyl; and Z is carboxyl, C.sub.2 -C.sub.5 alkoxycarbonyl or C.sub.1 -C.sub.5 carbamoyl, and its non-toxic salts, which are useful as antiulcers, gastric secretion inhibitors, central nervous system regulators, and labor inducing agents.
