Abstract

NEW MATERIAL:A compound of formula I [R1 is H or COOH-protecting group; >Z is formula II or III (R3 is H, halogen, etc.); R2 is H or OCH3; B is H, alkyl group, etc.; A is lower alkyl, aryl, heterocyclic ring, etc.; X and Y are O or S], and its salt.
EXAMPLE: 7β-[ α-Methylthio-α-( 4-ethyl-2,3-dioxo-1-piperazine-carboxamide )acetamido ]-7α-methoxy-3-[ 5-( 1-methyl-1H-tetrazolyl )thiomethyl ]-Δ3-cephem-4-carboxylic acid.
USE: An antibacterial having a wide antibacterial spectrum, and stable to β-lactamase.
PROCESS: A compound of formula IV (R14 is H or organic silyl or phosphorous) is reacted with a compound of formula V, its salt, or reactive derivative to give the compound of formula I or its salt.
