The reaction of 1 H -benzoimidazole-2-carbaldehyde with 4-oxo-2-thioxothiazolidin-3-ylcarboxilic acids was studied and the combinatorial library 5-(1 -benzoimidazol-2-ylmethylene)-4-oxo-2-thioxothiazolidin-3-ylcarboxilic has been prepared. structures target compounds 8a-f , 9 10a, b were confirmed by using NMR spectroscopy elemental analysis. synthesized selected National Cancer Institute (NCI)...

In the title compound, C(12)H(10)N(2)O(3), the five- and six-membered rings form a dihedral angle of 83.96 (6)°. The nitro group is twisted by 5.92 (8)° from the plane of the attached benzene ring. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into columns in the [100] direction, with a short distance of 3.725 (3) Å between the centroids of benzene rings inside t...

The tetrahydroazepine-annulated [3]ferrocenophane carbamate (4) was synthesized by two different linear routes starting from the readily available α-dimethylamino[3]ferrocenophane-ortho-carbaldehyde rac-6. The carbamate directed lithiation of 4 resulted in a selective attack at a (Cp)C-H bond at the higher substituted "lower" [3]ferrocenophane Cp-ring to eventually yield the respective ester (1...

In the title compound, C(16)H(11)ClN(2)O(2), the pyrazole ring makes dihedral angles of 11.88 (13) and 22.33 (13)° with the 3-chloro-2-hy-droxy-benzene group and phenyl rings, respectively. The phenolic hy-droxy group forms an intra-molecular O-H⋯N hydrogen bond with the imine N atom of the pyrazole unit. The formyl group is virtually coplanar with the pyrazole ring [dihedral angle = 4.5 (19)°]...

Abstract: Objective(s): In recent years, the chemistry of 2-chloroquinoline-3-carbaldehydes have received considerable attention owing to their synthetic and effective biological importance which exhibits a wide variety of biological activity, N1,N4-bis((2-chloroquinolin-3-yl)methylene)benzene-1,4-diamine derivatives that synthesized from 2-chloroquinoline-3-carbaldehydes may have biological ef...
