Abstract
A concise and highly efficient protocol for the synthesis of N-amino-2-pyridones has been developed by a four-component coupling of hydrazine hydrate, ethyl cyanoacetate, malononitrile and aromatic aldehydes in the presence of ZnO nanoparticles under mild conditions. The key advantages of this process are using an inexpensive and reusable catalyst, easy work-up and excellent yields.
