On the other hand, the reactivity-tuned coupling of selenophenyl donor 92 and thioethyl glycoside 93, mediated by NIS/TMSOTf, proceeded smoothly to give the disaccharide 94 as a single anomer in 77% yield. The Aloe group was selected to control the a-selectivity of the glycosylation reaction. [Pg.62]
