Asymmetric synthesis of β-amino-α-hydroxyphosphinic acid derivatives through hydrophosphinylation of α-amino aldehydes

Add time:07/31/2019    Source:sciencedirect.com

The diastereoselective synthesis of β-amino-α-hydroxyphosphinates was achieved by hydrophosphinylation of N,N-dibenzyl-α-amino aldehydes with ethyl ethylphosphinate catalyzed by (S)-ALB. The hydrophosphinylation using ethyl phosphinate afforded both syn- and anti-β-amino-α-hydroxy-H-phosphinates with high diastereoselectivities by tuning the chirality of ALB.
