Selectivity in the Trimethylsilylation and Acylation of Peptide Bonds, and its Application to Modification of the Enkephalins

N.m.r. spectra of N-acylated peptides, formed by reaction of protected peptides with silylating agents followed by acylation, have provided a means for assessing selectivity in the acylation of amide bonds.Amino-acids such as valine and phenylalanine prev
