摘要
The reduction of gamma-N,N-dibenzylamino-beta-ketophosphonates 4 derived from readily available (S)-tribenzylated amino acids teas achieved with catecholborane at -20degreesC affording gamma-amino-beta-hydroxyphosphonates 5 in high diastereoselectivity and good chemical yield. These reactions provide a new entry to enantiomerically pure gamma-amino-beta-hydroxyphosphonates. (C) 2002 Elsevier Science Ltd. All rights reserved.
