A base labile protecting group for peptide synthesis: 2,2 -Bis(4′-nitrophenyl)ethan-1-oxycarbonyl urethanes
摘要:
A base labile urethane (Bnpeoc) group derived from 2,2-bis(4'-nitrophenyl)ethan-1-ol has been developed as an amine protecting group. This protecting group may be cleaved using the reagents, DBN, DBU, DBU/HOAc and piperidine. The preparations of N-alpha-Bnpeoc amino acids and applications to peptide/glycopeptide synthesis are described.
