THE CHEMISTRY OF PEPTIDES RELATED TO METABOLITES OF TRICHODERMA SPP. 2. AN IMPROVED METHOD OF CHARACTERIZATION OF PEPTIDES OF 2-METHYLALANINE

4-Chlorobenzoylazide reacts with amino acid and peptide esters to give the 4-chlorobenzoyl derivatives in 60-90percent yield, at room temperature, without measurable racemization.The reaction also proceeds smoothly with hindered amines such as methyl 2-me
