Phenylselenoglycosides as novel, versatile glycosyl donors. Selective activation over thioglycosides

Article abstract of DOI:10.1016/0040-4039(91)80005-Q

Selective activation of phenylselenoglycosides over ethylthioglycosides with silver trifluoromethanesulfonate and anhydrous potassium gives an efficient synthesis of disaccharides from selenoglycoside donors and thioglycoside acceptors. Activation is quenched by addition of 1,1,3,3-tetramethylurea or collidine.
