  An efficient and highly stereoselective synthesis of nucleoside derivatives from furanoid 1,2-diols

  摘要：

  Reaction between suitably protected furanoid glycals 1b-4b, readily obtained from furanoid 1,2-diols (1a-4a), and different silylated pyrimidine bases, gave the corresponding 3',5'- and 3',5',6'-O-protected 2'-deoxy-2'-iodo-beta-D-xylo-pentofuranosyl 5-10 and beta-D-gluco-hexofuranosyl 11 nucleosides, respectively. Compound 5 has been transformed into its 2'-deoxy 12 and 2',3'-anhydro 14 derivatives. The high stereoselectivity of the reaction is discussed. (C) 1997 Elsevier Science Ltd.

  日期：1988.7

  We report here that 1-(2,3-anhydro-beta-D-lyxofuranosyl)cytosine has activity against the human immunodeficiency virus in vitro. A number of 2',3'-anhydro-beta-D-lyxofuranosyl nucleoside derivatives were prepared, but none had the activity of the title compound. New efficient procedures were developed for the synthesis of 3'-deoxy-3'-alkyl- and 3'-deoxy-beta-D-arabinosylpyrimidine derivatives.

  我们在这里报告1-（2,3-脱水-β-D-呋喃糖基）胞嘧啶在体外对人免疫缺陷病毒具有活性。制备了许多2'，3'-脱水-β-D-呋喃呋喃糖基核苷衍生物，但没有一个具有标题化合物的活性。开发了用于合成3'-脱氧-3'-烷基-和3'-脱氧-β-D-阿拉伯糖基嘧啶衍生物的新的有效程序。

  Treatment of 2',3'-anhydro pyrimidine nucleoside derivatives (1) with trimethylaluminum afforded 1-(3-deoxy-3-methyl-beta-D-arabinofuranosyl)pyrimidine derivatives (2) and 1-(2-deoxy-2-methyl-beta-D-xylofuranosyl)pyrimidine derivatives (3) as a mixture in approximately 2 : 1 - 3 : 1 ratio via ring-opening of the epoxide involving the nucleophilic attack of trimethylaluminum at the 3' or 2'-position of 1.
