Abstract

NEW MATERIAL:A compound of formula I (R1 and R2 are alkyl; n is 0W2; R3 is -OCOR5, -OXOOR6, etc. (R5,6 are aryl, alkyl; X is C, S); R4 is H, salt-forming cation, protecting group; Z is a group of II, III (R8 is acetoxy, carbamoyloxy, oxazolylthio, etc.).
EXAMPLE: 6-{D(-)-α-(4-Ethyl-2, 3-dioxo-1-piperazinecarboxamido)-α-[p-(benzoyloxy)-phenyl}acetamido]penicillanic acid of formula IV.
USE: Antibacterial agent having broad antibacterial spectrum, and remarkably effective to Pseudomonas aeruginosa, Myxomycetes, Friedlaender's bacillus, etc., and its synthetic intermediate.
PROCESS: Reaction of a compound V (R9 is organic silyl, phosphorus) with a compound VI or its reactive derivative affords the compound I.
