A process for the preparation of 3'-substituted-2',3'-dideoxynucleosides 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, 3'-fluoro-3'-deoxythymidine, and 3'-fluoro-3'-deoxyuridine.
提供了一种制备3'-取代-2',3'-二脱氧核苷的方法,利用廉价、非碳水化合物、无手性起始物质,并且进行高对映选择性和立体化学控制。该方法可用于制备具有药用重要性的化合物3'-氮杂基-3'-脱氧胸苷、3'-氮杂基-2',3'-二脱氧尿苷、3'-氟-3'-脱氧胸苷和3'-氟-3'-脱氧尿苷。
