Preparation method of 7,8-dihydroxy flavone

The invention relates to a preparation method of 7,8-dihydroxy flavone, and belongs to the technical field of synthesis of medical intermediates. The preparation method comprises the following steps:by taking pyrogallol as a raw material, introducing an acetyl group to synthesize DHF1; protecting three phenolic hydroxyl groups to synthesize DHF2; selectively reducing the ortho-hydroxyl group of the acetyl group to synthesize DHF3; carrying out an aldol condensation reaction on DHF3 and benzaldehyde to prepare DHF4; carrying out a cyclization reaction under the condition of iodine catalysis toobtain DHF5; and finally carrying out a hydrolysis reaction to generate the final product. The method is simple and convenient to operate, reasonable in reaction process, low in production cost, goodin product quality, free of environmental pollution and suitable for industrial production, wherein the content of the product is higher than 98%.
