Algar‐Flynn‐Oyamada (AFO) Reaction
View through CrossRef
AbstractFlavones have been reported to be synthesized via oxidative cyclization of 2′‐oxychalcones with hydrogen peroxide under alkaline conditions. This reaction is generally known as the Algar‐Flynn‐Oyamada reaction. A variety of 2‐hydroxychalcones with methoxy groups in different positions in the two aromatic nuclei smoothly undergo the AFO oxidation. This reaction has also been modified to convert 2′‐hydroxychalcones into flavones via SeO2oxidation. This reaction has wide application for preparation of flavones and flavonols.
