  Chemoenzymatic Synthesis of Novel 3‘- and 5‘-Carbazoyl Nucleoside Derivatives. Regioselective Preparation of 3‘- and 5‘-Alkylidencarbazoyl Nucleosides

  摘要：

  A chemoenzymatic procedure is described for the synthesis of 3'- and 5'-carbazoyl nucleoside derivatives 12a,b, 13a,b, 14b,c, and 30b, and these are prepared for the first time. This process involves the regioselective enzymatic alkoxycarbonylation of nucleosides and the subsequent transformation with hydrazine into novel carbazoyl nucleoside derivatives. Taking into account previously reported data (relative to nucleoside, hydrazone, carbazate, and aryloxyphenoxypropionate derivatives), 3'-alkylidencarbazoyl 2'-deoxynucleosides 15a,b-18a,b, 5'-alkylidencarbazoyl 2'-deoxynucleosides 19a,b-22a,b, 5'-alkylidencarbazoyl ribonucleosides of uridine 23c-26c, and 5'-alkylidencarbazoyl-2',3'-isopropylideneadenosine 31b-34b emerge as interesting targets since they combine structural features found in both therapeutic nucleoside derivatives and fungicide/herbicide nucleoside analogues.

  摘要：

  提出了获得3'-氨基木糖核苷13a，b和17a，b的一般方法。合成方案基于在核苷的3'活化位置的5'定向分子内亲核取代。进入的基团到达该位置的途径是从核苷的最受阻表面区域性和立体选择性地发生的。提出的方法学适用于核糖核苷和2'-脱氧核糖核苷，无论它们的碱基是否已硝化。
