چکیده
Condensation of 1-(9-alkyl-9H-carbazol-3-yl)-4-carboxy-2-pyrrolidinones with 2,3-diaminonaphthalene or o-aminophenol was carried out by melting a reaction mixture at 170–230 °C and provided new 2-substituted naphtho[2,3-d]imidazole and benzoxazole derivatives. Derivatives of 2-substituted naphtho[2,3d]imidazole were alkylated with an excess of ethyl iodide in the presence of potassium hydroxide. The structure of the study compounds was elucidated by 1H and 13C NMR spectroscopy. Their hole-transporting properties were investigated.

Synthesis of tetra-substituted phenanthroimidazole derivatives using SBA-Pr-SO3H
A one pot four-component reaction of 9,10-phenanthraquinone, aromatic aldehyde, aniline, and ammonium acetate was designed for the preparation of tetrasubstituted imidazoles (phenanthro[9,10-d]imidazole) derivatives in the presence of SBA-Pr-SO3H as a mesoporous solid acid catalyst. Phenanthro[9,10-d]imidazole derivatives were produced by the use of this technique in short reaction times and go...

Imidazole is a planar, five membered heteroaromatic molecule with pyrrole type and pyridine type annular nitrogens. Several approaches are available of imidazoles from alpha halo ketones, aminonitrile, aldehyde ect. Reactivity of imidazole and benzimidazole is referred from sets of resonance structure in which the dipolar contributors have finite importance. Imidazoles among the principal grou...

متن کاملOne-pot synthesis of 1- and 2-substituted naphtho[2,3-d][1,2,3]triazole-4,9-diones.
A one-pot three-component [2+3] cycloaddition for the synthesis of 1-alkyl 1H-naphtho[2,3-d][1,2,3]triazole-4,9-dione and 2-alkyl 2H-naphtho[2,3-d][1,2,3]triazole-4,9-dione has been developed. By taking the advantage of difference in basicity, both products can be obtained in good purity. The unique heterocyclic scaffolds of these two products could exert interesting chemical and biological pro...
