The copper-catalyzed azide-alkyne cycloaddition (CuAAC) has been used for the construction of 1,2,3-triazole containing steroids in good to excellent yields. Combination of propargylic glycosides and steroidal azides as reaction partner allowed the synthesis of a privileged class of natural product analogues. The versatility of this protocol makes this chemistry a useful attractive approach for the synthesis of target molecules. Georg Thieme Verlag Stuttgart · New York.
Gold-catalyzed glycosidations: Unusual cleavage of the interglycosidic bond while studying the armed/disarmed effect of propargyl glycosides

experimental part, p. 5269 - 5272 (2010/11/03)
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 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
