Multistep organic synthesis leading to the formation of triazinothiazoloquinoxalines involving cost effective rea-gents

Abstract

A simple and efficient chemical method has been attempted for the synthesis of biologically and commercially important 2-aryl [5-b] quinoxalin -4-thiones in moderate to excellent yields through cyclization reaction of ophenylenediamino using readily available and fewer costly reagents viz. oxalic acid, PCl5thiourea, aromatic aldehydes and ammonium thiocyanate at an ambient temperature.
