A novel type of nucleotide analogues, the 2′,3′-O-(1-diethylphosphono)alkylidene derivatives of ribonucleosides was prepared by redox reaction of diethyl chlorophosphite with various nucleoside orthoesters. Some of these compounds undergo interesting rearrangements when treated with nucleophiles. The configuration of the title compounds was determined by 2D-ROESY experiments. Biological activity of
新型的核苷酸类似物,核糖核苷的2',3'-O-(1-二乙基膦酰基)亚烷基衍生物是通过亚磷酸二乙酯与各种原核苷的氧化还原反应制备的。当用亲核试剂处理时,这些化合物中的一些会发生有趣的重排。通过2D-ROESY实验确定标题化合物的构型。还讨论了部分受保护的核苷酸类似物的生物活性。
