4-(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...

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.

The title compound, (I) C(28)H(24)N(4)O(4), is the trans diastereo-isomer of the compound 1-[2-(4-nitro-phen-yl)-6-(5-phenyl-3-isoxazol-yl)-1,2,3,4-tetra-hydro-4-quinolin-yl]-2-pyrrolidinone monohydrate, (II) [Gutierrez et al. (2011 ▶). Acta Cryst. E67, o175-o176]. The most obvious differences between the diastereo-isomers are the dihedral angles between the isoxazole ring and the benzene and p...

In the title compound, C(17)H(14)N(2)O(3), the oxazolone ring is essentially planar [maximum deviation = 0.004 (1) Å] and is oriented with respect to the phenyl and benzene rings at 10.06 (9) and 5.63 (8)°, respectively; the dihedral angle between the phenyl ring and the benzene ring is 15.69 (8)°. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into chains running along the a axis. Ne...

The title compound, C(28)H(24)N(4)O(4)·H(2)O, crystallizes with two organic mol-ecules and two solvent water mol-ecules in the asymmetric unit. The most obvious difference between the mol-ecules is the torsion angles between the isoxazole ring and the benzene and phenyl rings [47.0 (2)/56.4 (2) and 33.3 (2)/11.0 (2)°, respectively]. Another important difference is observed in the rotation of th...
