Synthesis of new fluorine-containing 3H-unsubstituted and 3-methoxycarbonyl-functionalized flavones

Abstract

An effective method of obtaining new 6,7,8-trifluoro- and 5,6,7,8-tetrafluorosubstituted 2-aryl-4-oxo-4H-chromene-3-carboxylates and 2-(polyfluoroaryl)-4Hchromene-4-ones has been developed. The chemical aspects of their synthesis were studied, specific features of the interaction were found depending on the structure of the initial fluorine-containing substrates and reaction conditions.
