Coupling reactions between 1-chloro-2,3-dideoxyribose and silylated pyrimidines have been examined from the point of stereoselectivity.When the reaction was carried out in chloroform, the selectivity was in the anomeric ratio of α:β = 4:6.On the other hand, the presence of tertiary amine raises the selectivity to α:β = 3:7.

Dideoxynucleosides were prepared in high optical purity from L-glutamic acid.The condensation reactions between activated 2,3-dideoxypentofuranoses and silylated purines or pyrimidines afforded separable β/α mixtures of dideoxynucleosides.
