Ethyl 4-(4-methoxy­phen­yl)-2-oxo-6-phenyl­cyclo­hex-3-ene-1-carboxyl­ate

The asymmetric unit of the title compound, C(22)H(22)O(4), consists of two independent mol­ecules (A and B) which differ significantly in the orientations of ethyl carboxyl­ate groups. The phenyl ring in mol­ecule B is disordered over two orientations with occupancies of 0.55 (2) and 0.45 (2). The c...

Sumario:The asymmetric unit of the title compound, C(22)H(22)O(4), consists of two independent mol­ecules (A and B) which differ significantly in the orientations of ethyl carboxyl­ate groups. The phenyl ring in mol­ecule B is disordered over two orientations with occupancies of 0.55 (2) and 0.45 (2). The cyclo­hexenone ring of both mol­ecules adopts an envelope conformation. The dihedral angle between the two aromatic rings is 81.12 (7)° in mol­ecule A and 70.8 (3)° in mol­ecule B [57.5 (4)° in the minor disorder component]. The crystal structure is stabilized by weak intermolecular C—H⋯O hydrogen bonds and C—H⋯π inter­actions.
