Radical polychloromethylation/cyclization of unactivated alkenes was achieved under metal-free conditions to afford ring-fused tricyclic indolones and benzoimidazoles.
在无金属条件下,对未活化的烯烃进行了自由基多氯甲基化/环化反应,得到了环融三环吲哚酮和苯并咪唑。

Photocatalytic Intramolecular [2 + 2] Cycloaddition of Indole Derivatives via Energy Transfer: A Method for Late-Stage Skeletal Transformation
cycloaddition of indolederivatives tethered with olefins at the N1 position has been considered thermodynamically unfeasible due to the high triplet excited-state energies. We describe visible light-promoted [2 + 2] cycloaddition with concomitant dearomatization of indolederivatives tethered with olefins at the N1 position via the energy transfer process, providing cyclobutane-fused polycyclic indoline derivatives
