METHOD OF PRODUCING 1,3-DICARBONYL COMPOUNDS CONTAINING DIBENZOSUBERENYL FRAGMENT Russian patent published in 2015 - IPC C07C49/21 C07C49/792 C07C49/813 C07C49/613 C07C45/45 C07C45/61 C07C69/608 C07C69/616 C07C67/08 C07D333/22 C07D239/62 C07D239/66

Abstract RU 2560727 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing 1,3-dicarbonyl compounds containing a dibenzosuberenyl fragment, which are of interest as a starting compounds for synthesis of biologically active substances, as well as ligands capable of coordinating metals. The method includes reacting dibenzosuberenol and 1,3-dicarbonyl compounds at 40°C for 30-180 min in a medium of 1,2-dichloroethane or nitromethane with catalysis of 5 mol % scandium triflate.

EFFECT: method enables to obtain the desired compounds with output of 63-86%.
