A series of hitherto unreported piperidone embedded α,β-unsaturated ketones were synthesized efficiently in ionic solvent and evaluated for cholinesterase inhibitory activities against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes. Most of the synthesized compounds displayed good enzyme inhibition; therein compounds 7i and 7f(More)
In the title compound, C(26)H(28)N(4) (2+)·2PF(6) (-), the complete cation is generated by a crystallographic twofold axis. The benz-imidazole ring is almost planar (r.m.s. deviation = 0.0207 Å) and makes dihedral angles of 50.12 (2)° with its symmetry-related component and 65.81 (2)° with the central benzene ring. In the crystal, mol-ecules are linked into(More)
The title compounds, N-acetyl-L-proline monohydrate, C7H11NO3·H2O, (I), and N-benzyl-L-proline, C12H15NO2, (II), crystallize in the monoclinic space group P21 with Z' = 1 and Z' = 2, respectively. The conformation of C(γ) with respect to the carboxylic acid group in (I) is C(γ)-exo or UP pucker, with the pyrrolidine ring twisted, while in (II), it is(More)
In the title compound, [Cr(C(18)H(12)F(3)P)(2)(CO)(4)], the Cr atom is octa-hedrally coordinated by four carbonyl ligands and the two tertiary phosphanes, which are trans to each other. The three benzene rings in one phosphane ligand make dihedral angles of 53.50 (9), 75.51 (10) and 80.63 (10)° with each other, while in the other ligand these angles are(More)
The asymmetric unit of the title compound, C22H18N4O2S2, contains two mol-ecules. In one of them, the dihedral angles between the central benzene ring and the phenyl rings are 16.97 (8) and 20.97 (8)°, while the phenyl rings make a dihedral angle of 37.87 (8)°. In the other mol-ecule, the corresponding values are 34.92 (7), 53.90 (7) and 60.68 (8)°,(More)
In the title compound, C(24)H(25)N(3)O(5), the eth-oxy group is disordered over two orientations in a 0.853 (14):0.147 (14) ratio. The benzimadazole ring system (r.m.s. deviation = 0.016 Å) makes a dihedral angle of 35.47 (7)° with the attached benzene ring. The pyrrolidine ring adopts an envelope conformation with a methyl-ene C atom as the flap. In the(More)
In the title compound, C(7)H(11)N(2) (+)·C(7)H(5)O(2) (-), the 2-amino-4,6-dimethyl-pyridinium cation and the benzoate anion are linked by two N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The H atoms in both the methyl groups are rotationally disordered, with fixed site occupancies of 0.50. In the crystal structure, the mol-ecules are stabilized(More)
In the title compound, C(18)H(13)F(2)NO(5)S(2), the complete mol-ecule is generated by a crystallographic inversion centre, and the O atom and the N-H group attached to the central ring are statistically disordered. The dihedral angle between the central and terminal benzene rings is 64.03 (6)°. In the crystal, N-H⋯O, C-H⋯F and C-H⋯O inter-actions link the(More)
The asymmetric unit of the title compound, (C(13)H(17)N(2)O)(2)[ZnCl(4)]·2H(2)O, contains two tetra-hydro-harmine cations, one tetra-chloro-zincate(II) anion and two water mol-ecules. In the cations, the two 1H-indole ring systems are essentially planar, with maximum deviations of 0.016 (2) and 0.018 (2) Å, and both tetra-hydro-pyridinium rings show a(More)
