The Lacunae identified in processing, analyzing and finding means of catalyst free Oxone mediated through C-3 oxidation of N-alkyl quinoxalin-2(1h)-one

A catalyst free oxone mediated synthesizing N-alkyl 1, 4-dihydroquinoxaline-2,3-dione has been developed by oxidation of the N-alkyl quinoxalin-2(1H)-one. The developed method is a novel, safest, cost-effective, industrially viable method and applicable for N-substituted and without substitution of 1,4-dihydroquinoxaline-2,3-dione. Consequently, the process is applicable to a broad spectrum of functionality. The reaction can be performed in all organic solvents without any further heating with an extended time and without generating side products. This novel synthetic methodology using Oxone is believed to be the shortest and most efficient to prepare various key intermediates which can be used for further derivatization to make the different biologically active molecules, the key feature of this methodology is not solvent specific, all organic solvents giving the optimum purity and quality using the same reaction condition.
