4-{[(4Z)-5-Oxo-2-phenyl-4,5-dihydro-1,3-oxazol-4-ylidene]methyl}phenyl acetate
The title mol-ecule, C(18)H(13)NO(4), shows a dihedral angle between the terminal acetyl group (r.m.s. deviation = 0.0081 Å) and remaining non-H atoms (r.m.s. = 0.0734 Å) of 53.45 (7)°. The configuration about the central olefinic bond is Z and overall the mol-ecule has a U-shaped conformation. Supra-molecular chains along the b-axis direction are found in the crystal structure. These are stabi...

In the paper by Asiri et al. [Acta Cryst. (2012), E68, o1154], the title and the chemical name of one of the reagents used in the synthesis are corrected.[This corrects the article DOI: 10.1107/S1600536812011579.].
متن کامل4-(2-Methoxybenzylidene)-2-phenyl-1,3-oxazol-5(4H)-one
The title mol-ecule, C(17)H(13)NO(3), adopts a Z configuration about the central olefinic bond. The 2-phenyl ring is almost coplanar with the plane of the oxazolone ring system, making a dihedral angle of 2.03 (11)°. The crystal structure is stabilized by π-π inter-actions between the oxazolone ring and phenyl ring of a neighbouring mol-ecule [centroid-centroid distance = 3.550 (3)Å], and by tw...
متن کامل2-Phenyl-4-(3,4,5-trimethoxybenzylidene)-1,3-oxazol-5(4H)-one
The title compound, C(19)H(17)NO(5), was synthesized as part of a continuing project involving the structures of oxazolone derivatives. The mol-ecule adopts a Z configuration about the central olefinic bond. The 2-phenyl ring is slightly twisted out of the plane of the oxazolone ring system by 11.2 (2)°. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
متن کامل4-{[4-(Dimethylamino)benzylidene]amino}-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one
The azomethine double-bond in the title Schiff base, C(20)H(22)N(4)O, has an E-configuration. The aromatic ring of the benzyl-idene portion (r.m.s. deviation 0.011 Å) and the five-membered pyrazolyl ring (r.m.s. deviation 0.033 Å) form a dihedral angle of 19.0 (1)°. The phenyl substituent is twisted by 55.0 (1)° with respect to the five-membered ring.
