Synthesis of thio- and selenoglycosides by cleavage of dichalconides in the presence of zinc/zinc chloride and reaction with glycosyl bromides

A convenient odorless methodology has been devised for the preparation of 1,2-trans-thio- and selenoglycosides through zinc-mediated cleavage of disulfides and diselenides and reaction of the thiolate and selenides formed in situ with glycosyl bromides. T

InBr 3 -Catalyzed Synthesis of Aryl 1,2- trans -Thio(seleno)glycosides

InBr 3 is demonstrated to be an efficient catalyst for reactions of fully acetated aldoses with aryl mercaptans or selenophenol at room temperature, rapidly furnishing the corresponding thioglycosides or selenoglycosides with exclusively 1,2- t

Odorless eco-friendly synthesis of thio- and selenoglycosides in ionic liquid

An environmentally benign odorless methodology for the preparation of 1,2-trans-thio- and selenoglycosides is reported. In a one-pot condition, the reductive cleavage of disulfides and diselenides using triethylsilane and borontrifluoride diethyletherate combination followed by the reaction of the in situ generated thiolate and selenoetes with glycosyl acetate derivatives in recyclable room-temperature ionic liquid, [BMIM]BFresulted in excellent yields of thio- and selenoglycosides avoiding the use of obnoxious thiols/selenols and metallic catalysts.

Indium(I) iodide mediated efficient synthesis of selenoglycosides

A convenient odorless methodology has been developed for the preparation of selenoglycosides through indium(I) iodide mediated cleavage of diselenides and reaction with glycosyl bromides. The yields were excellent in all cases. Retention of the configurat

Novel Glycosidation Methodology. The Use of Phenyl Selenoglycosides as Glycosyl Donors and Acceptors in Oligosaccharide Synthesis

The use of phenyl selenoglycosides as glycosyl donors and acceptors in glycosidation reactions is described.The versatility of these novel compounds is illustrated by the selective activation of both "disarmed" and "armed" phenyl selenoglycoside donors ov

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.
