Electrochemical catalyst an effective method for synthesis 2,3-dihydroquinazolin-4(1H)-one

A mild and efficient method was applied for the one-pot three-component synthesis of 2,3-dihydroquinazolin-4(1H)-one from the condensation between benzo[d]thiazol-2-amine, aryl aldehydes and 2H-benzo[d][1,3]oxazine-2,4(1H)-dione using electrochemical catalyst in an undivided cell in the presence of sodium bromide as an electrolyte. Electrochemical catalyst has many advantages such as clean work-up, fast, green process, green solvent and environment friendly method.
