The invention discloses a preparation method of glucoside and derivatives thereof. According to the method, all hydroxyl groups on a sugar molecule structure are acetylated, a ligand containing phenolic hydroxyl groups is prepared at the same time, then boron trifluoride-diethyl ether is used as a catalyst, the two substances are condensed to obtain tetraacetylated glucoside, and finally acetyl protecting groups are removed to obtain the required glucoside. The method can selectively catalyze hemiacetal hydroxyl of monosaccharide to react with hydroxyl to obtain glucoside, and the product is single. The method is simple in production operation and low in equipment requirement, can be used for synthesizing glucoside and derivatives thereof with similar structures, is green and environment-friendly, and can be used for large-scale production.
