3,15-Dimethoxy-10-methyltricyclo[9.4.0.02,7]pentadeca-1(11),2(7),3,5,9,12,14-heptaen-8-one

Abstract

The title molecule, C18H16O3, contains three fused rings, of which the seven-membered cyclohept-2-enone ring has a screw-boat conformation. The two methoxyphenyl rings make a dihedral angle of 50.4 (2)°. In the crystal, molecules are linked by intermolecular C—H...O hydrogen bonds, leading to a three-dimensional supramolecular architecture.
