Abstract

We report here a precise, in situ 31P {1H}-NMR method of assaying enantiopurity of α- hydroxyphosphonate esters, the products of the carbonyl hydrophosphonylation (Pudovik) reaction. This method is based upon a diazaphospholidine chiral derivatising agent (CDA) which satisfies all of the criteria for a precise assay;(i) derivatisation of α- hydroxyphosphonate esters is both rapid and clean,(ii) kinetic resolution is absent and (iii) ...
