The palladium(0)-catalysed coupling of 2-haloquinoxalines with alkynes, addition of one mol equivalent of bromine to the 2-alkynylquinoxalines thus produced and then reaction of the resulting dibromides with dipotassium trithiocarbonate produces thieno[2,3-b]quinoxalines.
通过钯(0)催化 2-卤代喹喔啉与炔烃的偶联,在生成的 2-炔基喹喔啉中加入一摩尔当量的溴,然后将生成的二溴化物与三硫代碳酸二钾反应,生成噻吩并[2,3-b]喹喔啉。
