Diastereoselective synthesis of chiral β-amino-α-hydroxy- H -phosphinates through hydrophosphinylation of α-amino aldehydes
摘要:
A stereodivergent synthesis of beta -amino-alpha -hydroxy-H-phosphinates was achieved by ALB-catalyzed hydrophosphinylation of N,N-dibenzyl-alpha -amino aldehydes tuning the chirality of the catalyst. (C) 2001 Elsevier Science Ltd. All rights reserved.
Asymmetric synthesis of β-amino-α-hydroxyphosphinic acid derivatives through hydrophosphinylation of α-amino aldehydes
摘要:
The diastereoselective synthesis of beta-amino-alpha-hydroxyphosphinates was achieved by hydrophosphinylation of N,N-dibenzyl-alpha-amino aldehydes with ethyl ethylphosphinate catalyzed by (S)-ALB. The hydrophosphinylation using ethyl phosphinate afforded both syn- and anti-beta-amino-alpha-hydroxy-H-phosphinates with high diastereoselectivities by tuning the chirality of ALB.
