Abstract

Cephalosporin C-type cpds. where R1 = HO, (1-8C) acyloxy, tert. amino R2 = HO (when R1 = HO, acyloxy) or O- (when R1 = tert. amino) or R1 + R2 = -O- R3 = (1-4C) alkyl, Ph, naphthyl, thienyl, benzothienyl, furyl, benzofuryl, indolyl, pyridyl; these may be substd. by: halogen, NO2, CF3, (1-4C) alkyl, (1-2C) alkoxy R4, R5, R6 = H, Me, Et. m, n = 0,1. together with pharm. accept. salts, esters and amides thereof. 7-Acylamino derivs. of cephalosporanic acid:- alpha-NH2-Ph-acetyl, both dl & L-forms alpha-NH2-beta-Ph-propionyl & L-form. Antibacterial agents.
