Abstract

NEW MATERIAL:A cephalosporin analog of formula I (X is acyl group; R1 is H or carboxylic acid-protecting group), and its salt.
EXAMPLE: (±)-cis-7-[2-( Thiophen-2-ly )acetylamino]-2-carboxy-1-azabicyclo[4,2, 0] oct-2-en-8-one.
USE: Antibacterials and an intermediate for their synthesis, effective against Gram- positive and Gram-negative bacteria.
PROCESS: A compound of formula II' is reacted with the carboxylic acid corresponding to the acyl group or its reactive derivative, if necessary in the presence of a base, to give the compound of formula I. A group NH2, OH, or COOH, which may be acylated, in the acylating group is preferably protected. After the reaction, the protecting groups is eliminated or converted into a salt.
