Oxidative radical cyclisations onto imidazoles and pyrroles using Bu3SnH

Aldabbagh, Fawaz,Bowman, W. Russell,Mann, Emma

, p. 7937 - 7940 (1997)

Oxidative radical cyclisation using Bu3SnH has been used for the synthesis of [1,2-c]-fused imidazoles and [1,2-a]-fused pyrroles from imidazolecarbaldehydes and acylpyrroles respectively. The intermediate nucleophilic N-alkyl radicals cyclise onto imidazole and pyrrole rings followed by oxidative re-aromatisation.
