โฆ Synopsis
Oxidative Radical Cyclizations onto Imidazoles and Pyrroles Using Bu 3 SnH. -The title reaction yields [1,2-c]-fused imidazoles or [1,2-c]-fused pyrroles via cyclization of a nucleophilic N-alkyl radical onto the heterocyclic ring followed by oxidative rearomatization.

Radical Cyclization onto Imidazoles and Benzimidazoles. -A new facile route to imidazoles and benzimidazoles is developed. Radical reaction of the benzimidazole (V) indicates that the presence of a leaving group at the C-2 position is essential for successful cyclization. -(ALDABBAGH,
