Abstract

NEW MATERIAL:A compound of formula I: (R1 is H or salt-forming cation; R2 is H, halogen, etc., R3 is aryl group which may be substituted by halogen and/ or OH; R4 is lower alkyl group; R5 is alkyl group; m and n are 0, 1, or 2; Z is formula II or III (R6 is acetoxy group)].
EXAMPLE: 3-Pyridyloxycarbonyl methyl ester of 6-[D(-)-α-(4-ethyl-2,3-dioxo-1- piperazine carboxamido)phenyl-acetamido]penicillanic acid.
USE: Antibacterials having a wide range of antibacterial spectrum, particularly effective for bacillus pyocyaneus, proteus vulgaris, bacteria pheumoniae, and prodigiosus, and improved oral absorption, stable to β-lactamases.
PROCESS: A compound of formula IV or its reactive derivative is reacted with a compound of formula V or its reactive derivative at the OH group to give the compound of formula I.
