Ethyl 6-amino-8-(4-chlorophenyl)-9-nitro-2,3,4,8-tetrahydropyrido[2,1-b][1,3]thiazine-7-carboxylate
In the structure of the title compound, C(17)H(18)ClN(3)O(4)S, the thia-zinane ring displays a twist-boat conformation. The 1,4-dihydro-pyridine ring is approximately perpendicular to the benzene ring [dihedral angle = 88.3 (1)°]. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond. In the crystal, mol-ecules are linked by N-H⋯O inter-actions into a C(8) chain al...

In the title mol-ecule, C(21)H(19)ClO(3), the cyclo-hexene ring adopts an envelope conformation, with all substituents equatorial. The plane through its five coplanar atoms makes dihedral angles of 12.75 (14) and 74.16 (8)° with the phenyl and benzene rings, respectively. The dihedral angle between the latter two rings is 81.73 (12)°. Inter-molecular C-H⋯O hydrogen bonds and intra-molecular C-H...

In the title compound, C(16)H(17)FN(2)O(4)·H(2)O, the dihedral angle between the heterocyclic ring and the benzene ring is 5.77 (9)°, that between the heterocycle and the ethoxy-carbonyl plane is 15.5 (1)°, and that between the heterocyclic ring and the cyclopropane ring is 67.75 (13)°. In the crystal structure, mol-ecules are linked into a ribbon-like structure along the c axis by N-H⋯O and O-...

The title compound, C20H27ClN2O3, was obtained via an original synthesis method. The central heterocyclic ring adopts a shallow envelope conformation, with the N atom bearing the cyclo-pentane ring as the flap [deviation from the other atoms = 0.442 (2) Å]. The cyclo-pentane ring adopts a twisted conformation about one of the CN-C bonds: the exocyclic C-N bond adopts an equatorial orientation. ...
