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.

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