Method for preparing icaritin intermediate
-
Paragraph 0085; 0091-0093, (2019/08/07)
The invention provides a method for preparing an icaritin intermediate. The method includes the steps of a, enabling phloroglucinol to react with one of a 2-benzyloxy acetylation reagent and 2-benzyloxy acetonitrile to obtain 2-benzyloxy-1-(2,4,6-trihydroxyphenyl)ethanone; b. subjecting a reaction product obtained from the step a and p-methoxybenzoyl halide to Baker-Venkataraman reaction so as toobtain 3-(benzyloxy)-5,7-dihydroxy-2-(4-methoxyphenyl)-4H-benzopyran-4-one; c. subjecting the reaction product obtained in the step b to hydrogenation so as to obtain the icaritin intermediate, namely 3,5,7-trihydroxy-2-(4-methoxyphenyl)-4H-benzopyran-4-one.
