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.

8-[(1E)-1-(2-Aminophenyl-iminio)eth-yl]-2-oxo-2H-chromen-7-olate.

Project description:The title Schiff base, C(17)H(14)N(2)O(3), exists as an NH tautomer with the H atom of the phenol group transferred to the imine N atom. The iminium H atom is involved in a strong intra-molecular N(+)-H?O(-) hydrogen bond to the phenolate O atom, forming an S(6) motif. In the crystal structure, N-H?O hydrogen bonds form a C(9) chain parallel to [100] and a C(11) chain parallel to [010], while C-H?O hydrogen bonds form a C(11) chain parallel to [010]. The combination of N-H?O and C-H?O hydrogen bonds generates R(4) (3)(30) rings parallel to the ab plane.

Project description:In the title compound, C17H18ClNO5, which was synthesized by reacting 4-chloro-3-formyl-coumarin, acetic acid and tert-butyl isocyanide, the acetamido side chain is convoluted with ring-to-side chain C-C-C-C, C-C-C-N and C-C-N-C torsion angles of -123.30?(14), -135.73?(12) and 176.10?(12)°, respectively.

2-Oxo-2H-chromen-4-yl 4-methyl-benzoate.

Project description:The asymmetric unit of the title compound, C17H12O4, consists of two independent mol-ecules.

4-Hy-droxy-3-[(4-hy-droxy-2-oxo-2H-3-chromen-yl)(3-thien-yl)meth-yl]-2H-chromen-2-one.

Project description:The whole mol-ecule of the title compound, C(23)H(14)O(6)S, is disordered over two sets of sites with refined occupancies of 0.8733?(12):0.1267?(12).
