Significance

A useful palladium-catalyzed, ­carbon monoxide mediated reductive N-hetero­cyclization of ortho-styryl nitro-heteroaromatic compounds 1 to afford bicyclic pyrrolo-fused heteroaromatic molecules 2 is described. The scope of the method was reasonably investigated. Bicyclic products were obtained in poor to excellent yields. No cyclization was observed when isoxazole or pyrrole was used as heteroaromates.
