An improved method for the synthesis of active esters of N-protected amino acids and subsequent synthesis of dipeptides

Article abstract of DOI:10.1055/s-1991-26545

4-Dimethylaminopyridine-catalyzed reaction of mixed carbonates 3 with N-protected amino acids 4 gave the corresponding active esters 5-9, from which dipeptides 11-18 were synthesized by aminolysis with amino acids 10.
