An effective Rh2(S-DOSP)4-catalyzed asymmetric cyclopentannulation of indolyl rings has been developed. Depending on the substitution pattern of the indole, two distinct regioisomeric products can be generated. These studies demonstrate that rhodium-catalyzed reactions of donor/acceptor carbenoids proceeding by means of zwitterionic intermediates can be carried out with very high asymmetric induction.
