5-disubstituted-α-D-glucofuranose proceeds with very high stereoselectivity to give stereochemically pure phosphinic and phosphinous acid esters, which are starting reagents for preparation of chiral organophosphorus compounds. Stereoselectivity of the reaction depends on the nature of bases, solvent, temperature and excess of chlorophosphine.
