✦ Synopsis


Abstract

Introduction of electron‐attracting substituents into the alcoholic component of methyl‐hippurate leads to activated esters which are characteristic acylating agents. A number of activated esters of hippuric acid are compared. The best acylating agent seems to be the cyanomethylester which is an easily accessible, cristalline, and stable compound, reacting easily with benzylamine at room temperature.

## Abstract A number of activated esters of amino acid and peptide derivatives were reacted with various organic amines, including amino acid esters. The good yields obtained, and the mild reaction conditions make it seem possible that the activated ester method of acylation may be of good use in p
