  摘要：

  描述了α羟基吡咯烷三环核苷3及其与丙酮的自发反应。在这种转化中，以完全的区域选择性和立体选择性的方式形成具有相当不寻常的分子骨架的高度官能化的多环核苷。该反应涉及一锅法形成三个新的键，其中两个是新的碳-碳键。提出了一种带有甲醇胺，亚胺离子和烯胺中间体参与的烯胺-亚胺机理，作为这种转化的合理解释。简要研究了反应范围，得出的结论是酮（R 1 COR 2）的性质对于NH初始攻击羰基至关重要。

  TSAO-T衍生的常见环烯胺与亲核试剂的反应合成新型的双环，三环和四环核苷

  摘要：

  我们在这里报告了一种有效的区域和立体选择性合成新的多环核苷的方法，该方法使用一种常见的环烯胺（7）作为起始原料。实际上，7的反应很容易通过5'- O -Tosyl TSAO-T在碱性非亲核条件下（碳酸钾）与不同种类的亲核试剂反应而制备，例如，基于氮，氧，硫和碳的亲核试剂，或提供的氨基酸，具有总的区域和立体选择性，新的双，三和四环核苷。这种直截了当的途径代表了这些化合物的原始且明确的区域和立体选择性途径。这些多环核苷中的某些可能是第二系列反应的有用中间体，这些反应可能导致结构上新的核苷的产生。

• Selective inhibition of Human Immunodeficiency Virus type 1 (HIV-1) by a novel family of tricyclic nucleosides

  Nucleoside 1, with an unusual tricyclic carbohydrate moiety, specifically inhibits HIV-1 replication while being inactive against HIV-2 or other (retro) viruses. In an attempt to increase the inhibitory efficacy against HIV-1, and to further explore the structural features required for anti-HIV-1 activity, different types of modifications have been carried out on this prototype compound. These include substitution of the ethoxy group at the C-4" position by alkoxy groups of different length, branching, conformational freedom or functionalization. In addition, the 4"-ethoxy group has been removed or substituted by other functional groups. The role of the tert-butyldimethylsilyl (TBDMS) group at the 2' position has also been studied by preparing the corresponding 2'-deprotected derivative or by replacing it by other silyl (tert-hexyldimethylsilyl) or acyl (acetyl) moieties. Finally, the thymine of the prototype compound has been replaced by N-3-methylthymine, uracil or thiophenyl. Some of these compounds were endowed with a 6- to 7-fold higher selectivity than the prototype 1. The tricyclic nucleosides here described represent a novel type of selective anti HIV-1 inhibitors, targeted at the HIV-1-encoded reverse transcriptase. (C) 2011 Elsevier B.V. All rights reserved.

  nucleophiles, or with amino acids afforded, with total regio- and stereoselectivity, new bi-, tri-, and tetracyclic nucleosides. This straighforward route represents an original and unambiguously regio- and stereoselective pathway to these compounds. Some of these polycyclic nucleosides may be useful intermediates for a second series of reactions that may lead to the generation of structurally new nucleosides

  An α hydroxy pyrrolidine tricyclic nucleoside 3 and its spontaneous reaction with acetone is described. In this transformation highly functionalized polycyclic nucleosides with rather unusual molecular skeletons are formed in a complete regio- and stereoselective way. The reaction involves the formation of three new bonds, two of them novel carbon−carbon bonds, in a one-pot way. An enamine−iminium
