  Synthesis of Nucleoside α-Thiotriphosphates via an Oxathiaphospholane Approach^†

  摘要：

  Nucleoside 5 '-O-(alpha-thiotriphosphates) were obtained in reactions of the appropriate nucleoside 5 '-O-(2-thio-1,3,2-oxathiaphospholanes) with pyrophosphate in the presence of DBU. The presented method allows also for preparation of alpha-seleno congeners and corresponding a-modified diphosphates.

  2-Alkoxy-2-thiono-1,3,2-oxathiaphospholanes are readily transformed into phosphorothioate monoesters of the corresponding alcohols in a one-pot process, involving the reaction with 3-hydroxypropionitrile in the presence of DBU, followed by treatment with aqueous ammonia. In this way a series of nucleoside-3′-O- and 5′-O-phosphorothioates were prepared, as well as phosphorothioate derivatives of selected polyols.

  2-烷氧基-2-硫代-1,3,2-氧硫磷烷可以方便地通过一步法转化为相应醇的磷酸硫代单酯，该方法涉及在DBU存在下与3-羟基丙腈反应，随后用氨水处理。通过这种方法制备了一系列核苷-3′-O-和5′-O-磷酸硫代酯，以及选定多元醇的磷酸硫代衍生物。
