1,2-Fused indoles and pyrroles were prepared via an efficient intramolecular photoaddition reaction of 1-(ω-alkenyl)-2-haloindole-3-carbaldehydes and 1-(ω-alkenyl)-2-chloropyrrole-3-carbaldehydes. The presence of an acyl group was necessary for the photocyclization reactions. The halogen-atom-retained exo- and endo-cyclization products were generally produced with results similar to those of an atom-transfer

Novel annelated α-carbolines have been synthesized from oxindole using three components in a one-pot procedure involving an intramolecular [3+2]-dipolar cycloaddition reaction of azides to nitriles.
