Synthesis of 12-Methyl-1, 2, 3, 4, 6, 7, 12, 12b-octahydro-2, 6-methanoindolo[2, 3-a]quinolizine

Triphenylphosphine Catalysed Facile Multicomponent Synthesis of 2-Amino-3-Cyano-6-Methyl-4-Aryl-4H-Pyrans

Triphenyl phosphine(PPh3), an efficient and reusable catalyst, catalysed the synthesis of 2-amino-3-cyano-6-methyl-4-aryl-4H-pyran-5-ethylcarboxylate derivatives by one-pot condensation of aromatic aldehydes, malononitrile and ethyl acetoacetate in EtOH-H2O (1:1) at reflux conditions. The results show that ...

Synthesis of new polyurethanes based on 5, 6, 7, 8 – tetrabromo – 2, 3 – dihydro – 1, 4 – phthalazine dione

In this work, 5,6,7,8-Tetrabromo-2,3-dihydro-2,3-bis(2-hydroxyethyl)phthalazine-1,4-dione is synthesized by the reaction of 5,6,7,8-tetrabromo-2,3-dihydrophthalazine-1,4-dione with 2-bromoethanol in the presence of triethylamine. The obtained monomer was polymerized with different diisocyanates, including hexamethylenediisocyanate (HMDI), tolylene-2,4-diisocyanate (TDI), isophoronediisocyanate ...

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...

1-(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...
