Rhodium(II) Catalyzed Intramolecular Reactions Between Vinyldiazomethanes and Pyrroles. Novel Synthesis of Fused 7‐Azabicyclo( 4.2.0)octadienes.

Abstract Intramolecular capture by pyrroles of vinylcarbenoids generated by rhodium(II) carboxylate catalyzed decomposition of vinyldiazomethanes results in the formation of fused 7-azabicyclo[4.2.0]octadienes or fused tropanes.
