Rh(II) carbene-mediated synthesis of methyl α- And β-ketopyranosides: Preparation of carbene precursors, quaternarization of the anomeric position, and ring opening of γ-lactones

Boultadakis-Arapinis, Melissa,Lescot, Camille,Micouin, Laurent,Lecourt, Thomas

, p. 587 - 604 (2011)

Methyl α- and β-ketopyranosides were efficiently prepared by carbene-mediated quaternarization of the anomeric position of corresponding aldopyranosides. Preparation of carbene precursors proved to be tedious and required a two-step procedure involving fi
