Abstract
NEW MATERIAL:A spiro compound of formula I [ring A is benzene or naphthalen ring each having one or more substituents [lower alkyl, NO2, halogen, acyl, SO2NH2, COOH, lower alkoxycarbonyl, lower alkylthio, lower alkylsulfinyl, lower alkylsulfonyl, CN, phenyl, or amino, hydroxyl, carbamoyl, ureido, thioureido or aminomethyl which may have a substitutent]].
EXAMPLE: Spino[benzo[b]furan-2(3H),1'-cyclopropan]-3-one.
USE: A gastric secretion suppressant anti-inflammatory agent or analgesic agent, e.g. a remedy for gastric or duodenal ulcer, acute or chronic gastritis, lumbago or arthritis, and an intermediate for the agents.
PROCESS: A compound of formula II is decarboxylated in the presence of a catalyst, e.g. a metal halide, to give the compound of formula I.
