Abstract

An efficient one-pot two-step synthesis of substituted-triazolo[4,3-a]quinoxalin-4(5H)-one has been developed. The 3-hydrazineylquinoxalin-2(1H)-one reacts with respective aldehyde to afford the individual hydrazineylidene intermediate which undergoes oxidative cyclization in the presence of ferric chloride hexahydrate (FeCl3.6H2O) to affords various substituted- triazolo[4,3-a]quinoxalin-4(5H)-one in good to excellent yields.
