Benzeneselenenyl triflate as an activator of thioglycosides for glycosylation reactions
Ito, Yukishige,Ogawa, Tomoya,Numata, Masaaki,Sugimoto, Mamoru
, p. 165 - 175 (2007/10/02)
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).
SULFENATE ESTERS AS GLYCOSYL ACCEPTORS: A NOVEL APPROACH TO O-GLYCOSIDES FROM THIOGLYCOSIDES AND SULFENATE ESTERS
Ito, Yukishige,Ogawa, Tomoya
, p. 4701 - 4704 (2007/10/02)
The reactions of thioglycosides and sulfenate esters were effected in the presence of Lewis acid to give corresponding O-glycosides.The stereoselectivity was highly dependent on the solvent.
