N-alkenyl acetoacetamides can be simply obtained in good yields by reaction of acetylketene, generated by thermolysis of 2,2,6-trimethyl-4H-1,3-dioxin-4-one in refluxing toluene, with imines possessing an α-hydrogen atom.
通过在回流甲苯中将2,2,6-三甲基-4H-1,3-二恶英-4-酮热解而生成的乙酰基乙烯酮与具有α-氢的亚胺反应,可以简单地以高收率简单地获得N-烯基乙酰乙酰胺原子。
