title: Rhodium-catalyzed intramolecular [3+2+2] cycloadditions between alkylidenecyclopropanes, alkynes, and alkenes.
abstract: A Rh-catalyzed intramolecular [3+2+2] cycloaddition is reported. The cycloaddition affords synthetically relevant 5,7,5-fused tricyclic systems of type 2 from readily available dienyne precursors. The transformation takes place with moderate or good yields, high diastereoselectivity, and total chemoselectivity.
