In this work, the direct conjugation of unprotected glycosyl diselenides with various biomolecules, including resorcinol, resveratrol, as well as the antitumor agent gimeracil, is reported. The Se-aglycon could be oxidatively cleaved from the sugar, priming these molecules for targeted cancer therapy. The generality and broad substrate scope of this novel procedure will also allow access to various
