Paragraph 0060; 0061; 0089; 0090; 0091, (2021/08/07)
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.

1-Silyl-2,6-diketones, readily prepared by addition of (silylmethyl)metal reagents to 1,5-lactols followed by oxidation of the resultant diols, can be efficiently transformed into 3-hydroxycyclohexanones, cyclohex-2-enones, or 1-(silylmethyl)cyclopentane-1,2-diols under nucleophilic, basic, or single electron-transfer reduction conditions, respectively. The latter cyclitols can be further transformed into 2-methylenecyclopentanols or 1-(hydroxymethyl) cyclopentane-1,2-diols by Peterson elimination or Tamao-Fleming oxidation, respectively.
