Thioglycosylation
WebJun 27, 2006 · A novel, green chemistry, glycosylation strategy was developed based upon the use of ionic liquids. Research studies demonstrated that thiomethyl glycosides could readily be activated with methyl trifluoromethane sulfonate, using 1-butyl-3-methylimidazolium tetrafluoroborate as a solvent. This green … WebAn efficient thioglycosylation of C(sp 2)−H bonds with thiosugars has been established for the first time. Using only Cu(OAc) 2 ⋅H 2 O as a catalyst and Ag 2 CO 3 as an additive in DMSO, the protocol proved to have broad scope, and a variety of complex thioglycosides have been prepared in good yields with exclusive β-selectivity.
