N2  - p-Methoxybenzyl esters of protected amino acids and peptides have been  prepared by imidazole-promoted condensation of the corresponding p-nitrophenyl  esters with p-methoxybenzyl alcohol. The products included several o-nitrophenylsulphenyl dipeptide p-methoxybenzyl esters, and the use of p-methoxybenzyl as a carboxyl-protecting group was illustrated by the synthesis of a protected  pentapeptide fragment of a modified insulin A-chain sequence involving selective  acidic cleavage of a-nitrophenylsulphenyl.
