1-(2-Methyl-6-nitro-4-phenyl-3-quinolyl)ethanone
In the title compound, C(18)H(14)N(2)O(3), the quinoline ring system is almost planar [maximum deviation = 0.013 (2) Å] and forms a dihedral angle of 60.36 (7)° with the benzene ring. The nitro group is slightly twisted from the attached quinoline ring system, forming a dihedral angle of 9.06 (19)°. In the crystal packing, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains pro...
متن کامل1-(6-Chloro-2-methyl-4-phenyl-3-quinolyl)ethanone
In the title compound, C(18)H(14)ClNO, the quinoline ring system is approximately planar with a maximum devation of 0.022 (1) Å and forms a dihedral angle of 62.70 (3)° with the phenyl ring. In the crystal, pairs of C-H⋯O inter-molecular hydrogen bonds link neighbouring mol-ecules into inversion dimers, forming R(2) (2)(14) ring motifs. These inversion dimers are stacked along the b axis. The s...

Insofar as one of the fundamenta l object ives of organic synthesis is the const ruct ion of complex molecules from simpler ones, the impor tance of synthet ic efficiency becomes immedia tely apparen t and has been well-recognized.1 The increase in molecula r complexity2 tha t necessar ily accompanies the course of a synthesis provides a guide (and a measure) of synthet ic efficiency. As a goal...
متن کاملMethyl 3-(4-{6-methyl-4-[3-(trifluoromethyl)phenyl]pyridazin-3-yloxy}phenyl)propanoate
In the title compound, C(22)H(19)F(3)N(2)O(3), the benzene rings of the trifluoro-methyl-phenyl and benzoyl-phenyl groups form dihedral angles of 41.89 (10) and 67.44 (10)°, respectively, with the pyridazine ring. The methyl-propanoate group is nearly coplanar with the attached benzene ring [dihedral angle = 3.9 (2)°]. The trifluoro-methyl group is disordered over two positions; the site-occupa...
متن کامل4-(4-Bromo-3-methyl-1H-pyrazol-1-yl)-6-(but-3-ynyloxy)pyrimidine
There are two mol-ecules in the asymmetric unit of the title compound, C(12)H(11)BrN(4)O. The dihedral angles between the pyrazole and pyrimidine rings are 1.28 (17) and 1.56 (17)° in the two mol-ecules. In one of the mol-ecules, the but-3-yn-yloxy side chain is disordered over two sets of sites in a 0.714 (8):0.286 (8) ratio.
