Abstract
Intermolecular [3 + 2] annulation of cyclopropylanilines with alkynes is realized using visible light photoredox catalysis, yielding a variety of cyclic allylic amines in fair to good yields. This method exhibits significant group tolerance particularly with heterocycles. It can also be used to prepare complex heterocycles such as fused indolines.
摘要
利用可见光光氧化还原催化，实现了环丙基苯胺与炔烃的分子间[3+2]环加成反应，以中等到良好的收率得到了多种环状烯丙基胺。该方法具有显著的基团容忍性，特别是对杂环。它还可用于制备复杂的杂环，如稠合吲哚啉。
