Synthesis and Pharmacological Investigations of Novel Pyrazolyl and Hydrazonoyl Cyanide Benzimidazole Entities

Various novel benzimidazole entities linked to pyrazolyl and hydrazonoyl cyanide substrates carrying aryl and heteroaryl groups (8a–e to 10a–e) were synthesized using new route syntheses and were focused on their pharmacological evaluation as one of the m

Synthesis of 5-(substituted phenylazo)-6-hydroxy-4-methyl-3--cyano-2- pyridones from ethyl 3-oxo-2-(substituted phenylazo)butanoates

A new procedure for the synthesis of known azo pyridone dyes is presented. A series of 5-(substituted arylazo)-6-hydroxy-4-methyl-3-cyano-2--pyridones were prepared from ethyl 3-oxo-2-(substituted phenylazo)butanoates and cyanoacetamide in acetone using potassium hydroxide as a catalyst by simple refluxing the reaction mixture. The structure of these dyes was confirmed by FT-IR, NMR and UV-Vis spectroscopy. Copyright 2011 (CC) SCS.
