Title:
PREPARATION METHOD FOR HEXAHYDROFURO-FURAN-OL DERIVATIVE, AND INTERMEDIATE OF DERIVATIVE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/196262
Kind Code:
A1
Abstract:
The present invention relates to the field of pharmaceutical synthesis, and in particularly relates to a preparation method for a hexahydrofuro-furan-ol derivative, and an intermediate of the derivative and a preparation method therefor. A dicarbonyl compound or a compound represented by formula DO is used as a starting material in the preparation method, wherein X1 and X2 are halogen or alkoxy identically or differently, or are constructed into a ring. In the preparation process for the hexahydrofuro-furan-ol derivative, an enzymic method is used to construct chirality; and such a technical means can prepare products with very high optical purity. The preparation method can commercialize and prepare a key intermediate (3R, 3aS, 6aR)-hexahydrofuro[2, 3-b]-3-ol of darunavir, which is a very economic way suitable for industrial production.
