Abstract
A new simple protocol for the direct synthesis of phosphonodipeptides from N-protected amino acids, diethyl 1-azidoalkylphosphonates and tertiary alky l phosphine (Bu3P, Me3P) was developed. The method is general and the coupl ing occurred with good yield (42-97%). Depending on the phosphine used and/ or mechanism operating during the condensation, the reaction can be accompl ished at room temperature, or on heating in toluene. (C) 2000 Elsevier Scie nce Ltd.
