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.
非对称取代的次膦酸和次膦酸的氯化物与(-)-1,2:3,5-二取代的-α-D-葡萄糖呋喃糖的反应以很高的立体选择性进行,从而得到立体化学纯的次膦酸酯和次膦酸酯,它们是用于制备手性有机磷化合物。反应的立体选择性取决于碱的性质,溶剂,温度和过量的氯膦。
