(E)-4-(2,5-Dimethoxy-benzyl-idene)-2-phenyl-1,3-oxazol-5(4H)-one.

ABSTRACT: The central aza-lactone ring in the title compound, C(18)H(15)NO(4), is planar (r.m.s. deviation 0.05, 0.12?Å) in both independent mol-ecules comprising the asymmetric unit. The benzyl-idene substituent is coplanar with this ring [dihedral angle between the planes = 1.8?(1)° in the first mol-ecule and 2.8?(1)° in the second], as is the phenyl substitutent [dihedral angle between rings = 4.6?(1) and 9.7?(1)°, respectively].

The central aza-lactone ring in the title compound, C(18)H(15)NO(4), is planar (r.m.s. deviation 0.05, 0.12 Å) in both independent mol-ecules comprising the asymmetric unit. The benzyl-idene substituent is coplanar with this ring [dihedral angle between the planes = 1.8 (1)° in the first mol-ecule and 2.8 (1)° in the second], as is the phenyl substitutent [dihedral angle between rings = 4.6 (1) and 9.7 (1)°, respectively]. ...[more]

(4Z)-4-Benzyl-idene-2-phenyl-1,3-oxazol-5(4H)-one.

Project description:In the title compound, C(17)H(13)NO(2), the benzene ring is twisted slightly out of the plane of the oxazole ring to which it is attached [dihedral angle = 7.98 (8)°]. Similarly, there is a twist [dihedral angle = 5.50 (8)°] between the oxazole and phenyl rings that are linked via the C=C bond [1.348 (2) Å]; the conformation about the latter is Z. In the crystal, the presence of C-H⋯O, C-H⋯π and π-π inter-actions [centroid-centroid distance = 3.5259 (9) Å] link the mol-ecules into a three-dimensional architecture.

2-Phenyl-4-(3,4,5-trimethoxy-benzyl-idene)-1,3-oxazol-5(4H)-one.

Project description: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.

4-(2-Methoxy-benzyl-idene)-2-phenyl-1,3-oxazol-5(4H)-one.

Project description: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 two weak inter-molecular C-H⋯π inter-actions. In addition, the crystal structure exhibits one weak intra-molecular C-H⋯N hydrogen bond.

4-[(3-Meth-oxy-anilino)methyl-idene]-2-phenyl-1,3-oxazol-5(4H)-one.

Project description: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. Neighbouring chains are inter-connected by π-π stacking, the centroid-centroid distance being 3.6201 (9) Å.

Ortho-rhom-bic modification of (E)-4-benzyl-idene-2-phenyl-1,3-oxazol-5(4H)-one: whole mol-ecule disorder.

Project description:The title mol-ecule, C(16)H(11)NO(2), is disordered about a pseudo-twofold rotation axis that approximately bis-ects the mol-ecule along the C=O double bond. The two overlapping components are planar [r.m.s. deviation = 0.10?Å in the major 0.537?(4) component and 0.07?Å in the minor component]. The two components are aligned at 1.8?(3)°.

2-[(E)-2,5-Dimethoxy-benzyl-idene]indan-1-one.

Project description:In the title compound, C(18)H(16)O(3), the mean plane of the nine-membered indane system makes a dihedral angle of 3.71 (17)° with the benzene ring of the dimethoxy-phenyl group. The mol-ecular conformation is stabilized by intra-molecular C-H⋯O hydrogen contacts. The crystal structure is stabilized by inter-molecular C-H⋯O inter-actions, which link neighbouring mol-ecules into one-dimensional extended chains along the [100] direction. In the structure, C-H⋯π inter-actions are also observed.

2-(Naphthalen-1-yl)-4-(naphthalen-1-yl-methyl-idene)-1,3-oxazol-5(4H)-one.

Project description:In the title compound, C(24)H(15)NO(2), the oxazole ring is oriented at dihedral angles of 10.09?(4) and 6.04?(4)° with respect to the mean planes of the naphthalene ring systems, while the two naphthalene ring systems make a dihedral angle of 4.32?(3)°. Intra-molecular C-H?N hydrogen bonds link the oxazole N atom to the naphthalene ring systems. In the crystal, inter-molecular weak C-H?O hydrogen bonds link the mol-ecules into centrosymmetric dimers. ?-? contacts between the oxazole and naphthalene rings and between the naphthalene ring systems [centroid-centroid distances = 3.5947?(9) and 3.7981?(9)?Å] may further stabilize the crystal structure. Three weak C-H?? inter-actions also occur.

4-[(Dimethyl-amino)methyl-idene]-2-(4-nitro-phen-yl)-1,3-oxazol-5(4H)-one.

Project description:The title mol-ecule, C(12)H(11)N(3)O(4), is essentially planar, the r.m.s. deviation for all non-H atoms being 0.068?Å. An intra-molecular C-H?N hydrogen bond occurs. The crystal packing is dominated by ?-? inter-actions [shortest centroid-centroid distance = 3.6312?(16)?Å], which lead to supra-molecular chains that are linked into a three-dimensional network via C-H?O contacts. The crystal was found to be a non-merohedral twin (twin law -1 0 0/0 -1 0/ 0.784 0 1), the fractional contribution of the minor component being approx-imately 22%.
