redox isomerization, for the synthesis of 3-allyl pyrroles is reported. In a single step, readily accessible simple starting materials are transformed into highly substituted pyrroles with high efficiency. The products obtained contain allyl substituents, which can be readily elaborated to other useful functional groups. The reaction proceeds through an unusual (3 + 2) cycloaddition/skeletal rearrangement/redox
报道了一种空前的级联策略,与氧化还原异构化一起用于合成3-烯丙基吡咯。只需一步,即可轻松获得的简单原料就可以高效地转化为高度取代的吡咯。获得的产物含有烯丙基取代基,其可以容易地修饰成其他有用的官能团。反应通过异常的(3 + 2)环加成/骨架重排/氧化还原异构化途径进行。
