Stereodivergent synthesis of β-amino-α-hydroxyphosphonic acid derivatives by lewis acid mediated stereosclective hydrophosphonylation of α-amino aldehydes
The highly diastereoselective synthesis of beta-amino-alpha-hydroxyphosphonic acid derivatives was achieved by Lewis acid mediated hydrophosphonylation of alpha-dibenzylamino aldehyde. Diastereofacial differentiation could be controlled in either a chelation or a nonchelation manner by simple tuning of the nature of phosphoric nucleophiles.
