Reagent switchable stereoselective β(1,2) mannoside mannosylation: OH-2 of mannose is a privileged acceptor†‡
Abstract
The discovery of novel conditions for highly β-stereoselective (>9 : 1) mannosylation of OH-2 of mannosides using a straightforward perbenzylthioglycoside donor has allowed ready assembly of β-mannosyl
