A new method has been developed for the beta-selective introduction of azido and cyano groups at the anomeric position of 2-deoxyribose derivatives. This method proceeds via the formation of a collidinium salt intermediate and allows for the stereoselective construction of 1 beta-azido- and 1 beta-cyano-2-deoxy-D-ribose derivatives. 2-Deoxy-D-ribose compounds bearing an acetoxy or tert-butoxycarbonyloxy group at their anomeric position performed well as starting materials for the formation of the corresponding 1 beta-azide and 1 beta-cyanide derivatives, respectively. H-1 NMR studies of the salt intermediates revealed that the nucleophilic substitution reaction of the salt intermediates proceeded in a S(N)2-fashion.
