Title:
METHOD FOR PRODUCING C-ARYL HYDROXY GLYCOXIDE DERIVATIVES
Document Type and Number:
WIPO Patent Application WO/2020/129899
Kind Code:
A1
Abstract:
In order to provide a method for the economical and efficient industrial production of C-aryl hydroxy glycoxide derivatives, the present invention provides a method for producing a C-aryl hydroxy glycoxide derivative represented by formula (I), the method comprising: a step for reacting a compound (II), which is represented by formula (II), with an organic zinc compound in the presence of a nickel catalyst or a palladium catalyst in order to obtain a reaction product; and a step for removing R5 from the reaction product to obtain the C-aryl hydroxy glycoxide derivative.
