- W1990468959 abstract "Abstract Reaction of nonsymmetrically substituted chlorophosphines (1–3) with (−)-1,2:3,5-di-O-isopropylidene-α-D-glucofuranose (1) or (−)-1,2:5,6-di-O-cyclohexylidene-α-D-glucofuranose (5) proceeds with high stereoselectivity to give stereochemically pure phosphinic acid esters (6–8), which are starting compounds for the preparation of chiral organophosphorus compounds. Reaction of benzyl-phenylphosphinous acid chloride with (1) leads to optically pure phosphinous acid ester (9). The stereochemistry of the reaction is studied in dependence on the nature of the base, solvent, temperature and excess of chlorophosphine.
