A New Asymmetric Synthesis of β-Aminophosphonic Acids

Pages 357-358 | Published online: 17 Mar 2008
 

Abstract

Addition of α-phosphonate carbanions to (S)-sulfinimines 2 gives N-sulfinyl-β-aminophosphonates 3 with a high diastereoselectivity (up to 10:1). The major diastereomer of 3 (R=Ph) was converted into (+)-(R)-β-amino-β-phenylethanephosphonic acid 5.
