7-Nitro-5H-1-benzothiopyrano[2,3-b]pyridin-5-one
In the mol-ecule of the title compound, C(12)H(6)N(2)O(3)S, the central heterocyclic ring is oriented at dihedral angles of 3.25 (6) and 2.28 (7)° with respect to the benzene and pyridine rings, respectively. The dihedral angle between the benzene and pyridine rings is 5.53 (7)°. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains.
متن کامل5H-1-Benzothiopyrano[2,3-b]pyridin-5-one
Mol-ecules of the title compound, C(12)H(7)NOS, with one half-mol-ecule in the asymmetric unit, are disordered about a crystallographic centre of inversion. Refinement showed that the C=O group is disordered with the S atom and the N atom is disordered over four positions. Adjacent mol-ecules are connected through C-H⋯O hydrogen bonds and π⋯π inter-actions (centroid-centroid distances of 3.635 ...
متن کامل1-Benzyl-5-ethyl-5-hydroxy-1H-pyrrol-2(5H)-one
The title compound, C13H15NO2, was obtained as a by-product in the Grignard reaction of malimide. The dihedral angle between the five-memebred ring (r.m.s. deviation = 0.005 Å) and the benzene ring is 67.20 (14)°. The benzene ring and the ethyl chain lie to the same side of the five-membered ring. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, generating C(6) chains propagating ...

In the title compound, C16H19NO3, the pyrrolidine ring is in a twist conformation. The dihedral angle between the di-hydro-furan ring [maximum deviation = 0.0016 (11) Å] and the phenyl ring is 47.22 (8)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming helical chains along the b-axis direction. The chains are further linked by C-H⋯π inter-actions to constitute a thre...
متن کامل(S)-5-Hexyl-1-[(S)-2-hydroxy-1-phenylethyl]-4-methoxy-1H-pyrrol-2(5H)-one
The title compound, C(19)H(27)NO(3), was obtained by the reaction of (3S,7aR)-7a-hexyl-7-meth-oxy-3-phenyl-2,3-dihydro-pyrrolo[2,1-b]oxazol-5(7aH)-one and triethyl-silane using titanium(IV) chloride as catalyst. In the mol-ecule, the phenyl and dihydro-pyrrolone rings form a dihedral angle of 83.8 (1)°. O-H⋯O hydrogen-bonding inter-actions lead to the formation of a chain parallel to the a axis.
