Carbohydrates as chiral auxiliaries: Synthesis of 2-hydroxy-β-D-glucopyranosides
A new 2-step, 1-pot procedure for the stereoselective glycosylation of allylic alcohols with 1,2-di-O-benzoyl-β-D-glucopyranosides to produce 2-hydroxy-β-D-glucopyranosides has been developed. The required precursor for the glycosylation was readily obtained from tri-O-benzyl-D-glucal in 2 steps (91% overall).
