A highly selective rhodium-catalyzed cyclization of tethered 3-allenylindoles is reported. In a smooth reaction, 1-vinyltetrahydrocarbazoles are obtained in excellent yields and enantioselectivities. Aside from a great functional group tolerance, this method requires neither the Schlenk technique nor the use of anhydrous solvents. Preliminary mechanistic investigations proved that the reaction proceeds via an intermediary formed spiroindolenine which rapidly undergoes an acid-catalyzed stereospecific migration.

Transacetalization reaction of the diethoxymethyl (DEM) protected indoles 2a,b,d,e with the polymer bound glycerol derivative 3 resulted in formation of the immobilized indoles 4a,b,d,e. Selective indole- functionalizations as well as quantitative and traceless cleavage could be demonstrated.
