  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.
