    摘要: A process for the preparation of 3'-substituted-2',3'-dideoxynucleosides and 2'-deoxynucleosides is provided that utilizes inexpensive, non-carbohydrate, acyclic, achiral starting materials and that proceeds with high enantiomeric and stereochemical control. The method can be used to prepare the pharmaceutically important compounds 3'-azido-3'-deoxythymidine, 3'-azido-2',3'-dideoxyuridine and 3'-fluoro-3'-deoxythymidine.
