摘要

In this paper we describe a simple and efficient solution-phase synthesis of N-methyl-N- nosyl-α-amino acids and N-Fmoc-N-methyl-α-amino acids. This represents a very important application in peptide synthesis to obtain N-methylated peptides in both solution and solid phase. The developed methodology involves the use of N-nosyl-α-amino acids with the carboxyl function protected as a phenacyl ester and the methylating reagent ...
