A new method for the stereoselective synthesis of nucleosides starting from acyclic epoxy aldehydes is developed. 2′-Deoxy-α-DL-ribonucleosides and α-L-lyxonucleosides are prepared by the reactions of the corresponding epoxy aldehydes with stannous salts of nucleoside bases utilizing stannous bromide as an activating reagent.
