3-[(E)-1-(Benzyl­oxyimino)eth­yl]-2-oxo-2H-chromen-7-yl acetate

The title compound, C(20)H(17)NO(5), was prepared by the reaction of 3-acetyl-2-oxo-2H-chromen-7-yl acetate with benzyl­oxy­amine. The mol­ecule adopts an E configuration with respect to the C=N double bond. The dihedral angles between the coumarin ring system, the phenyl ring and the C=N—O—C plane...

description The title compound, C(20)H(17)NO(5), was prepared by the reaction of 3-acetyl-2-oxo-2H-chromen-7-yl acetate with benzyl­oxy­amine. The mol­ecule adopts an E configuration with respect to the C=N double bond. The dihedral angles between the coumarin ring system, the phenyl ring and the C=N—O—C plane of the oxime unit are 35.83 (6), 35.8 (2) and 69.99 (15)°, respectively. In the crystal, a two-dimensional supra­molecular network is assembled through weak inter­molecular C—H⋯O hydrogen-bonding inter­actions.
