Synthesis of newer organic molecules with more favorable therapeutic properties and their conversion to derivatives which show optimum medicinal activity and synthesize the novel molecule or drug by combining different heterocyclic rings and the synthetic pathway followed, should be economic, safer, less time-consuming in order to prepare combinational molecule and also better creation against lethal diseases like malaria, TB, cancer etc.Thus, today needs to develop new rapid, convenient, selective, clean synthetic routes (greener approach) and new information, newer scaffolds in the chemical encyclopedia and idea about reaction mechanism which helps the drug discovery in medicinal chemistry. Finally, medicinal active molecular hybrids will continue to give a strong impetus for the discovery of novel chemical reactions, due to the value implicit in providing a molecule for study.
