A general procedure to obtain the 3'-aminoxylonucleosides 13a,b and 17a,b is presented. The synthetic scheme is based on the 5' directed intramolecular nucleophilic substitution at the 3'-activated position of the nucleoside. The approach of the incoming group to this position takes place regio- and stereoselectively from the most hindered face of the nucleoside. The methodology presented is applicable
