New type dispiroindolinones, dispiroimidazolidine-4,3′-pyrrolidine-2′,3″-indolinones unsubstituted at position 4′ of the central pyrrolidine ring, were synthesized by the 1,3-dipolar cycloaddition of azomethine ylides, generated from N-alkyl-substituted amino acids and isatines, to 5-methylidene-substituted 3-phenylhydantoin.

偶氮甲碱叶立德 [3+2] 环加成反应生成 5-methylidene-3-phenylhydantoin 的第一个例子

通过由 N-烷基生成的偶氮甲碱叶立德的 1,3-偶极环加成反应,合成了新型二螺吲哚酮,即在中心吡咯烷环的 4' 位未被取代的二螺咪唑烷-4,3'-吡咯烷-2',3"-吲哚酮-取代的氨基酸和靛红,到 5-亚甲基取代的 3-苯基乙内酰脲。
