3-(3-Methoxybenzylidene)chroman-4-one

Abstract

In the title compound, C17H14O3, the dihedral angle between the methoxybenzene unit and the benzene ring of the chromanone system is 64.12 (3)°. The crystal structure is stabilized by weak C—H...O interactions

“…The most commonly used procedure for the synthesis of homoisoflavonoids involves the condensation of chroman-4-one with an aromatic aldehyde in the presence of an acidic or basic catalyst (Shaikh et al, 2011). We have recently been involved in the synthesis and characterization of fluorinated homoisoflavonoids in the search for lead pharmaceuticals (Gopaul et al, 2012).…”

“…The title compound, 3-(3,4-dichlorobenzylidene)chroman-4-one (C 16 H 10 Cl 2 O 2 ), belongs to a class of compounds called homoisoflavonoids, which are C-16, α,β unsaturated carbonyl compounds containing two aromatic rings. They are a group of naturally occurring molecules that are structurally related to isoflavonoids but differ by containing one more carbon atom (Kirkiacharian et al, 1984;Gopaul et al, 2012).…”
