Synthesis of New Aza-Heterocyclic Based on 2-Pyridone

open access: yesChemistry Proceedings
In this work, we present new methods of synthesis of different molecules including a 2-pyridone nucleus. First, we prepared a series of 1H-free 2-pyridones and N-alkyl 2-pyridones from ethyl cyanoacetate, aromatic aldehydes, various acetophenone ...
