  A highly stereoselective synthesis of anti-HIV 2',3'-dideoxy- and 2',3'-didehydro-2',3'-dideoxynucleosides

  摘要：

  A general total synthetic method for the stereocontrolled synthesis of 2',3'-dideoxy- as well as 2',3'-didehydro-2',3'-dideoxynucleosides is presented. Introduction of an alpha-phenylselenenyl group at the 2-position of 2,3-dideoxyribosyl acetate directs the glycosyl bond formation to give greater-than-or-equal-to 95% beta-isomer. This 2'-phenylselenenyl nucleoside may be converted to either the 2',3'-dideoxynucleoside by treatment with n-Bu3SnH and Et3B at room temperature or to the unsaturated derivative by treatment with H2O2/cat. pyridine. The application of this method to the syntheses of pyrimidines (ddU, ddT, ddC), 6-substituted purines (ddA, ddI, 6-chloro-ddP, N6-Me-ddA), and 2,6-disubstituted purines (2-F-ddA, 6-chloro-2-amino-ddP) as well as selected 2',3'-didehydro-2',3'-dideoxy derivatives is reported.

  electron deficient 5-o-carboranyl moiety on uracil influenced the yield of the various isomers. In general, the compounds demonstrated weak anti-human immunodeficiency virus activity in primary human lymphocytes. No marked difference in the biological profile was noted for the various optical isomers, suggesting that the high lipophilicity of these nucleosides imparted by the carboranyl moiety overrides

  合成了5-o-碳烷基-2'，3'-二氢-2'，3'-二脱氧尿苷（d4CU）的四个异构体，并确定了它们在正常和癌细胞中的抗病毒活性和细胞毒性。在氧化消除和脱保护后，将所需的化合物甲硅烷基化的5-o-碳氧烷基尿嘧啶与受保护的D / L 2,3-二脱氧-2-苯基硒烯基核糖基乙酸酯偶联。尿嘧啶上电子缺陷的5-o-碳烷基部分的存在影响了各种异构体的产率。通常，这些化合物在原代人淋巴细胞中显示出弱的抗人免疫缺陷病毒活性。对于各种旋光异构体，没有观察到生物学特性的明显差异，
