title: Tandem visible light-mediated radical cyclization-divinylcyclopropane rearrangement to tricyclic pyrrolidinones.
abstract: 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.
