✦ Synopsis

The title compound, C 22 H 20 N 2 O 3 , was synthesized by the reaction of 4-methoxybenzaldehyde, 7-methoxy-2-tetralone and malononitrile in the presence of triethylbenzylammonium chloride in an aqueous medium. X-ray analysis reveals that the pyran ring and the fused six-membered ring adopt boat and skew-boat conformations, respectively.
