Abstract

A series of new carbacephem compounds which have substituted aminothiazolylglycyl side chain have been prepared starting from corresponding carbacephems with aminothiazolylmethoxyimino group. Among them, the compound having 3, 4-dihydroxybenzoyl group showed very sharp activity against Pseudomonas aeruginosa. Moreover, the optical resolution of α carbon of aminothiazolylglycyl moiety was carried out through preparation of optically active side chain and the (S)-isomer (KT-4380) was found to be the most active against Pseudomonas sp. as well as other Gram-negative strains.
