Controlled acetolysis of 3,6-anhydro-5-o-benzyl-1,2-o-isopropylidene-α-D-glucofuranose: Synthesis of 1-(3′,6′-anhydro-α-D-glucofuranosyl)thymine

Controlled acetolysis of 1,2-O-isopropylideneglucofuranose derivative 1 in Ac2O:AcOH:H2SO4 at 0°C is reported to isolate 2-acetoxy dimethylmethylenoxy glucofuranose derivative 2 in quantitative yield. Utility of 2 for the synthesis of alpha linked nucleoside 5a is demonstrated.

Synthesis of 1-(3′,6′-anhydro-2′-deoxy-β-D-glucofuranosyl)-thymine

Synthesis of bicyclic nucleoside 5 is described by coupling of 3 with bis(trimethylsilyl)thymine by use of Sn(IV)Cl as an activator. Synthesis of bicyclic 2′-deoxy analog 1 from 5 by radical deoxygenation of methylxanthate ester 6 is reported.
