Synthesis of the β-2',3'-unsaturated pentopyranosyl nucleosides and their 3'-hydroxymethyl congeners
Doboszewski,Blaton,Herdewijn
, p. 317 - 320 (1995)
Fusion of the glycal 3 and purines/pyrimidines without acid catalyst provides anomeric mixtures of the 2',3'-unsaturated pentopyranosyl nucleosides 4, which have been worked out to furnish the 3'-hydroxymethyl analogues, e.g. 5.
