A Ni-catalyzed [3 + 2] cycloaddition via CâC bond cleavage of methyleneaziridines under mild conditions was developed. This reaction gave substituted pyrroles with excellent regioselectivity and a pendant alkyne unit, which is advantageous for further derivatization.
在温和的条件下,开发出了一种通过 CâC 键裂解亚甲基氮丙啶的 Ni 催化 [3 + 2] 环加成反应。该反应生成的取代吡咯具有极佳的区域选择性和一个悬垂炔烃单元,有利于进一步衍生。

methyleneaziridines with o-, m-, and p-acetylpyridines proceeds very smoothly in the presence of a palladium catalyst, affording the biologically very important o-, m-, and p-pyridinylpyrrole derivatives in good to high yields. Not only ortho, meta, and para, but also related substrates, such as acetyl aromatics and hetarenes, can be used as the starting acetyl derivatives to synthesize related compounds to pyridinylpyrrole
