- We explored direct dehydrative coupling of tetrahydro-2H-pyran-2,3-diol or a 1,2-dihydroxy sugar with various alcohols using a range of arylboronic acids. Among the catalysts, 2-borono-4-trifluoromethylbenzoic acid efficiently promoted acetalization of tetrahydro-2H-pyran-2,3-diol. Ferroceniumboronic acid showed the best catalytic activity for glycosylation of the 1,2-dihydroxy sugar. The major products were 1,2-cJi-a-D-glucopyranosides.

The ring opening of α-D-1,2-anhydrohexapyranoses with phenols proceeded smoothly in ethyl acetate (neutral conditions) in the absence of metal ion catalysts or additives to stereoselectively furnish 1,2-cis-α-aryl glycosides as the major product and 1,2-t

Synthesis of 10-, 11- and 12-membered chiral benzolactones fused to furanose/pyranose sugars has been achieved in good to excellent yields using an intramolecular Sonogashira reaction. Positions 1-2, 3-5, 3-6 and 5-6 of sugar were utilized for the constru
Gold mediated glycosylations: Selective activation of propargyl 1,2-orthoesters in the presence of aglycones containing a propargyl moiety

Selective activation of propargyl 1,2-orthoesters in the presence of propargyl glycosides and propargyl ethers was studied; a catalytic amount of AuBr3 activated the propargyloxy group of the 1,2-orthoester thereby giving access to disaccharide
