Multicomponent cascade transformation of D-glucal to furan-appended triazole glycoconjugates.

Novel one-pot three- and four-component transformations of D-glucal to furan-based hydroxy triazole glycoconjugates have been achieved by sequential addition of reagents in the presence of Cu(OTf)(2)-Cu powder as catalysts. In general the carbohydrate-derived products were formed with high diastereomeric purity.
