4-(2-Nitrobenzyl)-3-phenyl-3,4-dihydro-2H-1,4-benzoxazin-2-ol
The title compound, C21H18N2O4, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. In both mol-ecules the oxazine ring has an envelope conformation with the hydroxyl-substituted C atom as the flap. The nitro-benzyl ring and the phenyl ring are almost normal to the mean plane of the benzooxazine ring system with dihdral angles of 85.72 (15) and 82.69 (15)°, respective...

The title compound, C(10)H(10)N(2)O, known as Edaravone (MCI-186), was crystallized from methanol. The two independent mol-ecules in the asymmetric unit are linked through an O-H⋯O hydrogen bond. One mol-ecule adopts a ketone form, while the other adopts an enol form. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains running along the b...

In the title compound, C(16)H(14)ClN, the conformation of the five-membered ring approximates to an envelope with a C atom as the flap. The dihedral angle between the aromatic rings is 78.71 (9)°.
متن کامل2-Phenyl-4H-3,1-benzoxazin-4-one
The title mol-ecule, C(14)H(9)NO(2), is nearly planar with a dihedral angle of 3.72 (4)° beteewn the plane of the phenyl ring and the 3,1-benzoxazin-4-one fragment. The mol-ecules are arranged into stacks parallel to the b axis via π-π stacking inter-actions [centroid-centroid distance = 4.2789 (11) Å] and the crystal packing is additionally stabilized by weak inter-molecular C-H⋯O inter-actions.
متن کاملtert-Butyl 4-isopropyl-2-oxo-6-phenyl-3,4-dihydro-2H-pyran-3-carboxylate
In the title compound, C(19)H(24)O(4), the six-membered lactone ring adopts an envelope conformation with the tert-butoxy-carbonyl and isopropyl substituents in axial positions, and the phenyl group in an equatorial position. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
