Synthesis of β-d-fructopyranosides with N-phenyl trifluoroacetimidate donor
摘要:
Fructopyranosyl N-phenyl trifluoroacetimidate was demonstrated to be effective glycosyl donor for beta-D-fructopyranosides preparation that exhibited good beta-selectivity and good yields. X-ray data of two beta-D-fructopyranosides were obtained and help to determine the anomeric configuration of these ketoses. (C) 2012 Elsevier Ltd. All rights reserved.
