Synthesis of unsymmetrical glycosyl diselenides by the treatment of symmetrical diselenides with glycosyl selenocyanates

Abstract

A novel reaction condition has been developed for the synthesis of unsymmetrical glycosyl diselenide derivatives in excellent yield by the reaction of glycosyl selenocyanates as selenol surrogates with symmetrical diselenides in the presence of hydrazine monohydrate at room temperature. The reaction metal-free condition is reasonably fast, simple, non-malodorous and suitable for scale-up.
