3-[(E)-1-(Benzyl-oxyimino)eth-yl]-2-oxo-2H-chromen-7-yl acetate.


ABSTRACT: 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 benzyl-oxy-amine. The mol-ecule 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 supra-molecular network is assembled through weak inter-molecular C-H?O hydrogen-bonding inter-actions.
