Synthesis of an Isomeric Nucleoside Enantiomers of 1,3-bis(1'-deoxy-β-ribofuranose-2'-yl)-thymine

Article Preview

Abstract:

The enantiomer isomeric nucleosides of 1,3-bis (1'-deoxy-β-ribofuranose-2'-yl)-thymine were synthesized from 1-deoxy-5-O-triphenylmethyl-ribose in high yield and selectivity. The key step is the coupling of 1-deoxy-5-O-triphenylmethyl-2,3-O-cyclosulphate-ribose and thymine using cesium carbonate as the base.
