Abstract
Glycosidation of silicon-connected glycosyl donors on polystyrene resin is described Thiophenyl glycoside 2a and glucopyranosyl fluoride 2 b reacted w ith glycosyl acceptor 3 (R-2 = Bn) to give disaccharide 4a in 96% and 70% y ields, respectively. Glycosidation of thiophenyl glucoside 2a (R-1 =Bn or B z) with glycosyl acceptor 3 (R-2 =Bn or Ac) yielded 4a-4c in satisfactory y ields and 4d in moderate yield. (C) 1999 Elsevier Science Ltd.
