Reduction of β-phthalimido-α-keto phosphonates, obtained through an Arbuzov reaction between the appropriate acid chloride and triethyl phosphite, with boranes and oxazaborolidine as catalyst, afforded β-phthalimido-α-hydroxy phosphonates in good yields and high diastereoselectivity. Deprotection of the amino group gave the title compounds.

Abstract
Reduction of β-phthalimido-α-keto phosphonates, obtained through an Arbuzov reaction between the appropriate acid chloride and triethyl phosphite, with boranes and oxazaborolidine as catalyst, afforded β-phthalimido-α-hydroxy phosphonates in good yields and high diastereoselectivity. Deprotection of the amino group gave the title compounds.File in questo prodotto:
