Abstract: To development thermal stable flavor, geranyl-β-D-glucopyranoside, cis-3-hexenyl-β-D- glucopyranoside and menthyl-β-D-glucopyranoside were prepared by the modified method of Koenigs-Knorr reaction, and compared with other methods such as phase-transfer and Lewis acid catalyst. When synthesis geranyl-β-D-glucopyranoside, a discussion of the effects of the catalyzer, temperature, time on yield was also made in this paper, the yield of the glycosidation reaction was 51% after optimized. In addition, the reaction process was monitored by TLC, HPLC, and IR, LC-MS, 1H-NMR and 13CNMR techniques were adopted to identify the structures of the glycosides. Research on glycosilation was extensively carried out.
