6-Chloro-2-methyl-4-phenyl-3-[1-phenyl-5-(2-thienyl)-4,5-dihydro-1H-pyrazol-3-yl]quinoline
In the title mol-ecule, C(29)H(22)ClN(3)S, the quinoline ring system, thio-phene ring and phenyl ring substituents are inclined at angles of 71.70 (7), 59.26 (9) and 81.61 (9)°, respectively, to the 4,5-dihydro-pyrazole ring. In the 4-phenyl-quinoline ring system, the phenyl ring makes a dihedral angle of 62.49 (7)° with mean plane of quinoline ring system. In the crystal structure, mol-ecules ...

In the title compound, C(16)H(15)N(3)O(2), the planar [maximum deviation 0.156 (2) Å] pyrazoline ring is nearly coplanar with the 3-nitro-phenyl group and is approximately perpendicular to the phenyl ring, making dihedral angles of 3.80 (8) and 80.58 (10)°, respectively. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
متن کاملTRANSFORMATION OF 2-BENZOYLAMINO-1-(?-NAPHTHYL)PROPAN-1-OL INTO 4-METHYL-1-PHENYL BENZO[f] ISOQUINOLINE RATHER THAN ITS 3-SUBSTITUTED ISOMER
The necessary conditions to transform hydroxyamide (1) and 2-oxazolines (2, 3) into 3- or 4-methyl benzo[f] isoquinolines (4, 5) has been established. The mechanism of these reactions has been proposed claiming the existence of the protonated 2-oxazoline (6) and the styrylamides (7) as intermediates.
