  Highly stereoselective synthesis of 2′-deoxy-β-ribonucleosides via a 3′-(N-acetyl)-glycyl-directing group

  摘要：

  A facile synthesis of 2'-deoxy-beta-ribonucleosides from 3'-O-(N-acetyl)-glycyl-protected 2'-deoxyribofuranose has been developed. The coupling reactions between the protected 2'-deoxyribose and silylated bases exhibited beta-selectivity up to 98% presumably via a 1',3'-participation mechanism. The 3'-directing group can be introduced and removed easily under mild conditions. This approach provides an efficient and highly stereoselective entry for the synthesis of 2'-deoxy-ribonucleosides.

• An asymmetric approach to 2-deoxynucleosides via organosulfur building blocks as chemical chameleons

  asymmetric synthesis of 6-N-benzoyl-5'-O-benzyl-2'-deoxyadenosine and its a anomer from non-carbohydrate building blocks is achieved in 7 steps. The sequence builds the basic structures using bis(methylthio)methane and methylthiomethyl phenyl sulfone as both nucleophilic and electrophilic building blocks, a feature that suggests their behavior as chemical chameleons. The asymmetric induction is achieved

  由非碳水化合物结构单元实现6-N-苯甲酰基-5'-O-苄基-2'-脱氧腺苷及其异构体的不对称合成可通过7个步骤完成。该序列使用双（甲硫基）甲烷和甲硫基甲基苯基砜作为亲核和亲电构件来构建基本结构，这一特征表明它们作为化学变色龙的行为。利用基于催化不对称环氧化的动力学拆分来实现不对称诱导。
