Some (p-hydroxyphenyl)benzylmethylsulfonium salts were prepared. These compounds generated a benzyl cation and converted not only N-acylamino acids but also N-acylpeptides into their corresponding benzyl esters without causing the racemization.
INTRAMOLECULAR CATALYTIC MECHANISMS INVOLVED IN THE ALKALINE HYDROLYSIS OF p-NITROPHENYL ESTERS OF α-CARBOBENZOXY AMINO ACIDS

A study on the alkaline hydrolysis of p-nitrophenyl esters of α-carbobenzoxy amino acids, in the presence and absence of free amino acids as catalysts, are reported.The effect of free amino acids represents an interesting model for the study of the cataly
