  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.
