Homologation of L-phenylalanine to ketomethylene and hydroxyethylene dipeptide isosteres via 2-thiazolyl amino ketone intermediate
摘要:
A highly efficient route is presented for the synthesis of N-protected isosteric dipeptides Phepsi[COCH2]Gly and Phepsi[CH(OH)CH2]Phe from L-phenylalanine through 2-thiazolyl alpha-amino ketone and delta-amino-gamma-hydroxy-(E)-alpha,beta-enoate derivatives as key intermediates.
