2-Methoxy-3-[(3,4,5-trimethoxyanilino)methylidene]-3,4-dihydro-2H-1-benzopyran-4-one
The title molecule, C(20)H(21)NO(6), adopts a keto–amine tautomeric form. An intramolecular N—H⋯O hydrogen bond, classified as a resonanse-assisted hydrogen bond, influences the molecular conformation; the two benzene rings form a dihedral angle of 24.6 (1)°. In the crystal structure, weak inter...
