β¦ Synopsis
Reaction of chlorides of nonsymmetrically substituted phosphinic and phosphinous acid with (-)-l,2:3,5-disubstituted-ct-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.

## Abstract A straightforward synthesis of homoallylβ and allylphosphanes has been developed using __n__BuLiβmediated hydrophosphination of conjugated dienes. In all the cases the phosphorus atom of the reacting phosphane attacked thesterically less demanding side of the diene exclusively. In addit
