  Tandem Visible Light-Mediated Radical Cyclization–Divinylcyclopropane Rearrangement to Tricyclic Pyrrolidinones

  摘要：

  Visible light promoted single electron reduction of bromocyclopropyl cyclization scaffolds enabled by photoredox catalysis initiates a novel tandem radical cyclization/sigmatropic rearrangement to generate tricyclic pyrrolidinones having considerable molecular complexity from simple, readily available starting materials. Furthermore, subtle variations to substrate structure afford a wide array of reaction diversity.
