2-Aza-1,3-butadienes bearing alkoxyl substituent were obtained easily by the reaction of ketimines with orthoesters. The reaction proceeded smoothly by the addition of small amount of p-toluenesulfonic acid. When acetals were used in place of orthoesters, the corresponding 2-aza-1,3-butadienes were similarly prepared.
带有烷氧基取代基的2-氮杂-1,3-丁二烯是通过酮亚胺与邻醇醚的反应轻松获得的。在加入少量对甲苯磺酸后,反应顺利进行。当使用醚基替代邻醇醚时,相应的2-氮杂-1,3-丁二烯同样得以制备。
