One of the most attractive synthetic approaches preferred by organic chemists is the use of heterogeneous catalyst in enhancing the efficacy of a broad range of organic synthesis. Heterogeneous catalysis is being used in the fine chemicals industry because of the need for more eco-friendly production methods. Heterocycles possess the great interest in the medicine and many mankind applications. In view of this many industries and research laboratories worldwide concerned in the synthesis of structurally modified analogues of heterocyclic derivatives in search of safer and more and more potent drugs than existing ones. Especially isoquinolinones and isoquinoline-1,3-dione core structure containing heterocycles exhibits wide range of spectrum in pharmaceutical industry. ThIS book mainly concerned about the synthesis of isoquinolinones and isoquinoline-1,3- diones through reusable heterogeneous ZnO nanoparticles as a catalyst from homophthalic acid and various amines.
