3‐Amino‐1‐(3,4‐methyl­enedioxy­phenyl)‐9‐methoxy‐5,6‐dihydro‐1H‐benzo[f]chromene‐2‐carbonitrile

The title compound, C22H18N2O4, was synthesized by the reaction of 7‐methoxy‐2‐tetralone and 3,4‐methyl­enedioxy­benzyl­idenemalononitrile 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...

Summary:The title compound, C22H18N2O4, was synthesized by the reaction of 7‐methoxy‐2‐tetralone and 3,4‐methyl­enedioxy­benzyl­idenemalononitrile 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 screw‐boat forms, respectively.
