N-芳基噁唑烷二酮衍生物的合成

Synthesis and Herbicidal Activity of N-Aryloxazolidone Derivatives

通过芳基异氰酸酯与2-羟基-3-甲基-3-丁烯酸乙酯的加成环化反应，合成了8噁个取代芳基唑烷二酮衍生物，收率41%-72%。其结构经表征确认正确。

N-Aryloxazolidone derivatives were prepared in 41%-72%yield through the addition cyclization reaction of ethyl 2-hydroxy-3-methyl-3-butenenate with different aryl isocyanate. Their structures were identified by MS and 1H NMR.
