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

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.

Potential usefulness of sugar 1,2 thio ortho esters in iodonium-promoted glycosidation

Sugar 1,2 thio ortho esters can be condensed with terminal glycosyl acceptors using iodonium-ion sources (IDCP and NIS/TfOH) as activators.IDCP- or NIS/TfOH-assisted glycosidation of sugar 1,2 thio ortho esters with primary hydroxyl groups of "armed" or "
