An Outline to Preparation of Biological Active Benzimidazoles Using Microwave Approach

Benzimidazole and its derivatives have a lot of diverse biological activities, including antimicrobial, antiviral, antidiabetic, anticancer activity. Different benzimidazole derivatives in good yield produced by condensation of ortho-phenyl diamine with aromatic aldehyde using various catalysts. In this work, we reviewed many microwaves assisted reactions involving the synthesis of benzimidazole derivatives.
