Imidazole moiety when fused with other heterocyclic system form numerous compounds with different types of pharmacological and biological activities. In this review, we discussed a comprehensive analysis of the synthetic methodologies and reaction mechanisms for imidazo‐fused heterocyclic molecules. These molecules represent a crucial class of compounds due to their significant applications and versatile chemical reactivity. This article meticulously examined various synthetic routes for the construction of imidazo‐fused heterocycles, ranging from traditional methods to modern approaches such as microwave‐assisted reactions, NPs‐catalyzed reactions, light‐mediated synthesis, electrochemical reactions, and transition metal‐free synthesis routes. By consolidating the current knowledge and highlighting future directions, this review aims to serve as a treasure for research community in the fields of organic chemistry, medicinal chemistry, and material science.

We report a visible-light-assisted tandem oxidative 5-exo-dig cyclization of 1,6-enynes for the synthesis of aminated C-3 aryloylated benzofuran, furopyridine, benzothiophene, and indole derivatives. The nitrogen-centered radical generated in situ from Naminopyridinium salt initiates the consecutive formation of C−N, C−C, and C−O bonds. The methodology exhibits good functional group tolerance and regioselectivity, furnishing products in good to excellent yields at room temperature. Preliminary biological screening of synthesized molecules reveals their potential as anticancer agents.
