Multicomponent Cascade Transformation of D-GIucaI to Furan-Appended Triazole Glycoconjugates.

Novel one-pot threeand four-component transformations of n-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. [ABSTRACT FROM AUTHOR]
