Abstract

α-sulfobenzylpenicillins(I) and its salts, useful as antibacterial agent against gram-neg. as well as gram-pos. bacteria, including pseudomonas and penicillin G-resistant strain, were prepd. by converting RCH2O3 SCHPhCOR1(II, R= branched alkyl group of from 4 to 14 carbon atom, R1=OH) into I(R1=Cl), which was then reacted with either silylated 6-aminopenicillanic acid or its Na salt. The product was isolated by treatment with NaOH soln.
