| Summary: | 碩士 === 靜宜大學 === 應用化學系 === 100 === 2,3 - Unsaturated glycosides have been found in many natural compounds.They not only possess natural stereocenter but also play important intermediate to synthesize chiral drugs and natural products. There are considerable research and development value.
Treatment of 3,4,6-tri-O-acetyl-D-glucal with various alcohols in the presence of 1.8 equivalents of FeCl3-SiO2 under solvent-free conditions at room temperature, the corresponding 2,3 – unsaturated-O- glycosides were obtained in good yields. FeCl3-SiO2 was be recovered easily and reused efficiently.
