been shown to catalyze the coupling of acetyl-protected carbohydrates with N-silylated indoles to give the corresponding N-glycosides. Preliminary mechanistic experiments indicated that catalysis occurs through formation of a Cu–indolide complex with concomitant formation of TMS-OTf which together activate the sugar and deliver the indole nucleophile.
