Facile synthesis of norwogonin, isoscutellarein, and herbacetin

An expeditious synthesis of norwogonin, isoscutellarein, and herbacetin, has been accomplished by a strategy featuring a borylation of sterically hindered aryl iodide and a one-pot oxidation to generate the C-3 and C-8 OH groups. The total synthesis gives excellent yields and conventional flash column chromatography is not needed for purification.

Preparation method of flavonoids

The invention discloses a preparation method of flavonoids. The method comprises the following step: in a solvent, in the presence of iodine and a silver salt or in the presence of iodine and a copper salt, performing an iodination reaction on a compound 1 to obtain a compound 2. Raw materials used in the method are easy to acquire, and the method has high yields and simple post processes, and does not need column chromatography.
