Versatile gold catalyzed transglycosidation at ambient temperature

Glycosidation with stable alkyl glycosyl donors using a catalytic amount of gold salts is promising. Herein, 1-ethynylcyclohexanyl glycosides are identified as novel donors at room temperature and mechanistic investigation showed that the leaving group simply extrudes out.

Gold-catalyzed glycosidations: Unusual cleavage of the interglycosidic bond while studying the armed/disarmed effect of propargyl glycosides

Armed/disarmed effect of propargyl glycosides in the presence of AuBr 3 is studied. Observed that oxophilic AuBr3 cleaves interglycosidic bond of an armed disaccharide resulting in the formation of a disaccharide and a 1,6-anhydro sugar. Trisaccharides were obtained after fine tuning the reactivity of the glycosyl donor with different protecting groups.

Gold-catalyzed glycosidations: Synthesis of 1,6-anhydro saccharides

Various 1,6-anhydro sugars are synthesized utilizing salient features of gold-catalyzed glycosidations. All the reactions occurred under mild conditions in the presence of 7 mol % of AuBr3 enabling easy synthesis of 1,6-anhydro sugars from corr
