Benzeneselenenyl triflate as an activator of thioglycosides for glycosylation reactions

Ito, Yukishige,Ogawa, Tomoya,Numata, Masaaki,Sugimoto, Mamoru

, p. 165 - 175 (1990)

A new method for the activation of thioglycosides was developed by use of benzeneselenenyl triflate (PhSeOTf), which, upon reaction with either a primary or secondary sugar HO-group, afforded O-glycosides under extremely mild reaction conditions.The reaction was applicable to various 1-thiohexosides 2-6 as well as to a 2-thioglycoside 20 derived from N-acetylneuraminic acid (NeuAc).
