An efficient synthesis of new imidazo[1,2-b]pyridazinederivatives was effected by treating 3,6-dichloropyridazine with various 2-hydroxyethylamines following by imidazole ring formation under Swern oxidative conditions. Some mechanistic aspects of the cyclization step are discussed.
通过在Swern氧化条件下形成咪唑环,用各种2-羟基乙胺处理3,6-二氯哒嗪,可以有效合成新的咪唑并[1,2- b ]哒嗪衍生物。讨论了环化步骤的一些机械方面。
