8-Phenyl-3,4,6,7,8,8a-hexahydro-1H-pyrrolo-[2,1-c][1,4]oxazin-6-one.

ABSTRACT: 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 mol-ecule of the title compound, C(26)H(28)N(2)O(2)S, the pyrrolidine ring adopts an envelope conformation and the tetra-hydro-pyridine ring is in a half-chair conformation; these two rings are trans-fused. The dihedral angle between the pyridine- and sulfonyl-bound benzene rings is 36.15?(5)°. In the crystalline state, the mol-ecules are linked into a two-dimensional network parallel to the ab plane by C-H?O and C-H?? inter-actions.

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?? links and aromatic ?-? 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.
