N-methylation of peptides on selected positions during the elongation of the peptide chain in solution phase

An efficient and general solution-phase method for the site-specific N-methylation of peptides has been developed. This novel procedure involves synthesis of N-nosyl protected peptides and their subsequent N-methylation with diazomethane. Its efficiency w
