Synthesis of the β-2',3'-Unsaturated Pentopyranosyl Nucleosides and Their 3'-Hydroxymethyl Congeners
摘要:
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.
