An attempt to construct an indole-fused azabicyclo[3.3.1]nonane framework

The structural motif of an indole-fused azabicyclo[3.3.1]nonane is common in many biologically significant indole-based natural products. Because of its structural complexity, this N-bridged scaffold has become an enticing target for organic chemists. Many efficient strategies have been developed to access this ring system synthetically, but a radical approach remains unexplored. Herein, we report a radical-based strategy to construct an indole-fused azabicyclo[3.3.1]nonane structural framework. Although our initial attempt to use a Cp
