Some hitherto unreported thiazolo[3,4- a]quinoxaline derivatives have been synthesised in excellent yields via a one-pot, three-component reaction of benzene-1,2-diamines, ethyl bromopyruvate and aryl isothiocyanates in MeCN, for the first time. The protocol avoids the use of any catalysts or chromatographic separations and provides a wide range of novel thiazolo[3,4- a]quinoxalines.

AbstractA rapid and an efficient one-pot method for the synthesis of quinoxalines catalysed by ZnO-beta zeolite at room temperature is described. This environmentally benign method provides several advantages over methods that are currently employed such as a simple work-up, mild reaction conditions, good to excellent yields, and a process to recover and reuse the catalyst for several cycles with consistent activity.
