The literature survey reveals that the individual coumarin and heterocyclic molecules have biological and pharmaceutical activities. Moreover, integrated coumarinfused heterocyclic compounds have shown interesting biological and physiochemical properties and thus, designing and development of coumarin-fused heterocyclic molecules are of great interest in the field of synthetic organic chemistry. Several coumarin-fused heterocyclic molecules have been synthesized by using different strategies such as multistep method, one-pot multi-component protocol, coupling and condensation method. The wide applications of integrated coumarin-fused heterocyclic molecules stimulated interest among researchers to develop different methodologies for the synthesis of novel fused molecules. As a consequence, several research articles, papers and review articles have been published in the literature. In this review article, we have presented various methods for the synthesis of different class of coumarin-fused heterocyclic molecules and their applications in chemical, optical, pharmaceutical and other useful applications.
