Abstract:
6-acylamido-6-methoxypenicillanic acids are obtained by reacting a 6-acylamidopenicillanic acid with mercuric acetate in methanol to yield a methyl. alpha. -methoxypenicilloate. Esterification of the latter with isobutylene affords the methyl, t-butyl diester of the methoxypenicilloic acid which undergoes selective hydrolysis in base to provide the free. alpha. -carboxylic acid half t-butyl ester of the penicilloic acid. The latter on reaction with dicyclohexylcarbodiimide affords an oxazolone-thiazolidine of the formula ##STR1## WHICH WITH 98% FORMIC ACID PROVIDES A COMPOUND OF THE INVENTION.
