The reaction of α-hydroxyamino oximes with ethyl acetoacetate and ethyl α-methylacetoacetate yields 2-[2-(hydroxyimino)alkyl]-1,2-oxazol-5(2H)-ones. In the reaction of alkylaromatic α-hydroxyamino oximes with ethyl acetoacetate, the intermediate imidazo[1,2-b]-[1,2]oxazolones were isolated, which then convert to the target compounds.
α-羟氨基肟与乙酰乙酸乙酯和α-甲基乙酰乙酸乙酯的反应产生2- [2-(羟基亚氨基)烷基] -1,2-恶唑-5(2H)-1。在烷基芳族α-羟基氨基肟与乙酰乙酸乙酯的反应中,分离出中间体咪唑并[1,2- b ]-[1,2]恶唑酮,然后转化为目标化合物。
