The invention provides a synthesis method of voglibose, and solves the technical problems that in an existing synthesis method of voglibose, raw materials are difficult to obtain, high in price, large in investment, low in yield and not suitable for industrial production. The synthesis method comprises the steps: synthesizing a compound V by taking glucose monohydrate and sodium acetate as raw materials through eleven reaction steps; and preparing a compound VIII from the compound V through an addition reaction, a ring-opening reaction and an aldol condensation reaction, and thus obtaining voglibose through amination reduction of the compound VIII. The synthesis method of voglibose can be widely applied to the technical field of voglibose synthesis methods.

A mild, convenient and transition-metal-free protocol for the synthesis of aryl 1-thioglycosides is presentedviaarynes generatedin situcombined with glycosyl thiols in the presence of TBAF(tBuOH)4. The methodology provides a general and efficient way to prepare a series of functionalized thioglycosides in good to excellent yields with a perfect control of the anomeric configuration at room temperature. In addition, the reaction conditions tolerate a variety of the pentoses and hexoses, and the reaction also performs smoothly on protected monosaccharides and disaccharides.
