A method for preparing full-benzyl protected alcohol glycoside β-

The present invention discloses a method of preparing an all-benzyl alcohol protected β- glycoside, which is characterized by the full-propynyl benzyl glycoside with a solvent by stirring 1mol: 10 ~ 100L mixture, alcohol was added with stirring receptor, then FeCl3 carried out / C solid acid catalyst and a temperature of 20 ~ 100 ℃ glycosylation reaction, after the reaction the catalyst was filtered off, the filtrate was concentrated to give product was purified full-benzyl protected alcohol β- glycoside acceptor is benzyl alcohol, methanol, propylene alcohol, n-butanol and propargyl alcohol glycosides equivalent ratio of 1.0 to 5.0: 1. The present invention over the prior art process is simple, easy to operate, low cost, high yield, avoiding the use of highly toxic material, not pollute the environment, a substrate for a wider range of application, environmental protection and cost-effective the whole synthesis benzyl alcohol protected β- glycoside.
