An Overview of Palladium-Catalyzed Fabrication of Some Heterocyclic Frameworks

Heterocycles are the largest family of organic compounds due to their wide applications as therapeutic agents, synthetic intermediates, scaffolds, building blocks or fine chemicals. Heterocyclic compounds are continuously used in material science, biotechnology, pharmaceutical and agrochemical industries. In the past few years, the use of transition metal complexes especially palladium as a heterogeneous catalyst has become a trend for the synthesis of various organic compounds. Pd-catalyzed reactions have proven to be effective ways for synthesising a variety of heterocyclic compounds, which are a popular class of molecules in chemical study. Hence, in this review we have discussed the palladium catalyzed synthesis of various heterocyclic compounds i,e. furan, indole, quinoline, coumarin and some other heterocycle derivatives.
