METHOD OF PRODUCING 3-ARYL-1H-BENZO[f]CHROMENE DERIVATIVES Russian patent published in 2016 - IPC C07D311/92

Abstract RU 2597363 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing 3-aryl-1H-benzo[f]chromenes, containing aromatic substitutes in first and third positions, by reducing 2-aroyl-1,2-dihydronaphtho[2,1-b]furans under action of zinc in acetic acid in molar ratio 1:5 in medium of boiling of acetic acid.

EFFECT: technical result is simplification of technological process and cheap production, which is achieved due to use of readily available 1,2-dihydronaphtho[2,1-b]furan, zinc and acetic acid without need to use an inert atmosphere.
