Recent developments on nano-ZnO catalyzed synthesis of bioactive heterocycles

Heterocycles are the core structural motif in the majority of organic compounds, known so far [ 1 , 2 ]. Heterocyclic moieties are very common in naturally occurring compounds and are important because of their significant biological efficacies that include anticancer [ 3 ], cytotoxic [ 4 ], anti-malarial [ 5 ], anti-microbial [ 6 ], anti-inflammatory [ 7 ], anti-oxidant [ 8 ] and many more [ 9 , 10 ].
