Abstract
NEW MATERIAL:A penicillin derivative and its intermediate of formula I (R is H or benzyl).
EXAMPLE: Benzyl 6β-[ (benzyloxycarbonylhexamethyleneiminomethylene)amino ]- 2',2-dimethylpenam-3α-carboxylate.
USE: Useful as a remedy for diseases of a man and an animal having improved antimicrobial activity against Gram-positive and Gram-negative bacteria.
PROCESS: A 1- ( benzyloxycarbonyl-ethylthiomethylene )hexamethyleneimmoniumtetrafluoroborate of formul II is reacted with benzyl ester of 6-aminopenicillanic acid of formula III usually in a solvent, e.g. acetone, under cooling or at room temperature to give a compound of formula IV in which R is benzyl group. The resultant compound is hydrogenated if desired to give the compound of formula I in which R is H.
