摘要：

How to fuse heterocycles: The direct enamine-imine isomerization of indoles and subsequent intramolecular imino-ene has been observed under Lewis acid catalysis. This unique reaction occurred for indoles that contain a tethered olefin functionality, and led to fused indoline heterocycles with excellent diastereocontrol (see scheme).
