8-Methoxy-3-(4-methylbenzylidene)-6-(prop-1-enyl)chroman-4-one

Abstract

In the title compound, C21H20O3, the tolyl ring makes a dihedral angle of 31.11 (6)° with the benzene ring of the chromanone unit. The pyrone ring adopts a half-chair conformation. The molecular structure is stabilized by a weak intramolecular C—H...O interaction and the crystal packing is stabilized by weak intermolecular C—H...O interactions and a C—H...π interaction.
