A novel cascade Friedel–Crafts alkylation/Michael addition/aromatization reaction of 2‐vinylindoles with α,β‐unsaturated aldehydes has been developed for the construction of functionalized tetrahydrocarbazoles. The products were obtained in up to 97% yield and with excellent stereoselectivities (ee up to>99%, dr up to>99:1).

The totalsynthesis of iheyamine A from readily available ethyl 2-aminocinnamate and 5-methoxyindole-2-carboxaldehyde is described. The cyanide-catalyzed imino-Stetter reaction of an aldimine derived from ethyl 2-aminocinnamate and 5-methoxyindole-2-carboxaldehyde provided the desired unsymmetrical 2,2′-bisindole-3-acetic acid derivative. The subsequent introduction of an amino group at the C-3′ position
A Brønsted acid catalyzed tandem Diels−Alder/aromatization reaction of 2-vinylindoles has been developed. The reaction provides a highly efficient and concise approach to 3-indolyl-substituted tetrahydrocarbazoles with various substituents in high yields under mild conditions.
Homo‐ and cross‐[4+2] cycloadditions of 2‐alkenylindoles, catalyzed by cationic halogen‐bonddonors, were developed. Under mild reaction conditions, 3‐indolyl‐substituted tetrahydrocarbazole derivatives were obtained in good to excellent yields. Experimental and quantum calculation studies revealed that the electrophilic activation of 2‐alkenylindoles was achieved by C−I⋅⋅⋅π halogen bonds.
