3-Phenyl-1H-pyrrolo[2,1-c][1,4]oxazin-1-one.

ABSTRACT: The mol-ecule of the title compound, C(13)H(9)NO(2), is slightly twisted with a dihedral angle of 4.85?(9)° between the nine-membered ring system and the phenyl ring. The nine non-H atoms of the 1H-pyrrolo[2,1-c][1,4]oxazin-1-one system are coplanar [r.m.s. deviation = 0.0122?(2)?Å]. In the crystal, weak inter-molecular C-H?O inter-actions link mol-ecules into chains along [10]. The crystal studied was an inversion twin with a 0.48624?(9):0.51376?(9) domain ratio.

The mol-ecule of the title compound, C(13)H(9)NO(2), is slightly twisted with a dihedral angle of 4.85 (9)° between the nine-membered ring system and the phenyl ring. The nine non-H atoms of the 1H-pyrrolo[2,1-c][1,4]oxazin-1-one system are coplanar [r.m.s. deviation = 0.0122 (2) Å]. In the crystal, weak inter-molecular C-H⋯O inter-actions link mol-ecules into chains along [10]. The crystal studied was an inversion twin with a 0.48624 (9):0.51376 (9) domain ratio. ...[more]

Project description:In the title compound, C(13)H(15)NO(2), the hexa-hydro-pyrrolo-[2,1-c][1,4]oxazine fragment is disordered over two conformations (A and B) in a 0.656 (5):0.344 (5) ratio. The five-membered ring is similarly disordered and adopts an envelope conformation in A, while in B this ring is nearly planar [maximum deviation = 0.088 (1) Å]. The six-membered rings in both A and B exhibit chair conformations. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into ribbons propagating in [010].

Project description:In the title compound, C(26)H(31)NO(6)S, the five-membered pyrrolidine ring adopts an envelope conformation and the six-membered thia-zine ring is in a distorted chair conformation. The crystal packing is stabilized through an inter-molecular C-H⋯O inter-action, generating inversion-related R(2) (2)(10) ring motifs.

1-Phenyl-1H-naphtho-[1,2-e][1,3]oxazin-3(2H)-one.

Project description:In the title compound, C(18)H(13)NO(2), the naphthalene (r.m.s. deviation = 0.025 Å) and benzaldehyde (r.m.s. deviation = 0.006 Å) groups are oriented at a dihedral angle of 89.48 (4)°. The oxazine group is oriented at dihedral angles of 13.36 (4) and 85.08 (5)°, respectively, with respect to the naphthalene and benzaldehyde fragments. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds generate R(2) (2)(8) loops. The dimers are linked into [010] chains via N-H⋯O hydrogen bonds. Weak C-H⋯π links and aromatic π-π stacking between the centroids of the naphthalene phenyl rings [centroid-centroid separation = 3.5977 (8) Å] help to consolidate the packing.

2-Hy-droxy-2,3,5,10,11,11a-hexa-hydro-1H-pyrrolo-[2,1-c][1,4]benzodiazepine-5,11-dione.

Project description:The seven-membered ring of the title compound, C(12)H(12)N(2)O(3), which is fused with the phenyl-ene ring, adopts a boat-shaped conformation (with the methine C atom as the prow and the phenyl-ene C atoms as the stern); the H atom on the methine linkage exists in an axial position. The five-membered ring that is fused with the seven-membered ring adopts an envelope conformation (with the C atom bearing the hy-droxy substituent representing the flap) [the deviation from the plane defined by the other four atoms is 0.200?(7)?Å in one mol-ecule and 0.627?(5)?Å in the other]. The two independent mol-ecules are disposed about a pseudo center of inversion and are connected by a pair of N-H?O hydrogen bonds. Adjacent dimers are linked by a pair of O-H?O hydrogen bonds, generating a chain running along the b axis.

Project description:The title compound, C(17)H(25)ClN(3)O(3) (+)·Cl(-)·H(2)O, is a monohydrated hydro-chloride salt of a new derivative of mosapride, which is a pharmaceutical compound possessing gastrointestinal pro-kinetic activity. The chloride anion accepts hydrogen bonds from the NH group of the pyrrolooxazine fused-ring system and from the amine group, and the water mol-ecules form hydrogen bonds that bridge between the chloride anion and the C=O bond of the amide.
