Epimerization of 2'-carbonylalkyl-C-glycosides via enolation, beta-elimination and intramolecular cycloaddition.

Treatment of 2'-carbonyl-alpha-C-glycopyranosides of gluco, galacto, manno, 2-deoxy, and 2-azido sugars with 4% NaOMe resulted in anomeric epimerization to give their respective beta-anomers in good to excellent yields. The epimerization of the 2'-aldehyd
