2-Amino-4-methyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile
In the title compound, C(10)H(12)N(2)S, the thio-phene ring is essentially planar (r.m.s. deviation = 0.0290 Å). The two C atoms of the cyclo-hexene ring (at positions 6 and 7) are disordered over two sets of sites in a 0.810 (5):0.190 (5) ratio. The cyclo-hexene rings in both the major and minor occupancy conformers adopt a half-chair conformation. In the crystal, there are two types of N-H⋯N ...
متن کاملEthyl 2-(pyridine-4-carboxamido)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate
In the title compound, C(17)H(18)N(2)O(3)S, the dihedral angles between the thio-phene ring and the ethyl ester group and the pyridine-4-carboxamide unit are 7.1 (2) and 9.47 (11)°, respectively. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds between the tetra-hydro-1-benzothio-phene and the pyridine-4-carb...
متن کامل3-(1-Ethyl-1H-pyrrole-2-carboxamido)propionic acid monohydrate
The title compound, C(10)H(14)N(2)O(3)·H(2)O, was synthesized by alkyl-ation of methyl 3-(1H-pyrrole-2-carboxamido)-propion-ate with ethyl bromide, followed by saponification and acidification. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules, forming layers parallel to the ac plane.

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. ...

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...
