Gold(I)-Catalyzed Synthesis of Tetrahydrocarbazoles via Cascade [3,3]-Propargylic Rearrangement/[4 + 2] Cycloaddition of Vinylindoles and PropargylicEsters. -Highly substituted tetrahydrocarbazole derivatives are obtained in high yields and diastereoselectivities. Furthermore, a preliminary screening for an asymmetric version of this reaction is also described. -(PIROVANO*, V.; ARPINI, E.; DELL'ACQUA, M.; VICENTE, R.; ABBIATI, G.; ROSSI, E.; Adv. Synth.
