The first example of 1,3-dipolar cycloaddition reactions of nitrones to vinylidenecyclopropanes is described. The nitrones react with the C1′–C2′ double bond of vinylidenecyclopropanes to give the corresponding 4-cyclopropylidene-isoxazolidines in moderate yields.
描述了硝酮与1,1-亚乙烯基环丙烷的1,3-偶极环加成反应的第一个例子。硝酮与亚乙烯基环丙烷的C1'–C2'双键反应,以适当的收率得到相应的4-环亚丙基-异恶唑烷。
