摘要:
The enantioselective hydrophosphonylation reaction of diisopropyl phosphite with aldimine furnished alpha-amino phosphonates with high enantioselectivities by means of a chiral phosphoric acid. DFT calculation of the effect of 3,3'-substituents of the phosphoric acid revealed the reason for the high enantioselectivities. (C) 2009 Elsevier Ltd. All rights reserved,
