Abstract

NEW MATERIAL:Compounds of formula I (R is H, methyl, carboxymethyl, sulfonatomethyl).
EXAMPLE: Mandelic 1-methyl-tetrazol-5-yl-thiol ester.
USE: Acylating agent for amines and hydrazines: they show excellent functions as an activated ester in the synthesis of cephalosporin.
PREPARATION: A compound of formula II is made to react with mandelic acid or its derivative in a solvent at -20W50°C to give the compound of formula I.
