Abstract

The transition-metal-catalyzed intramolecular cyclization of indole derivatives represents an attractive route for the synthesis of polycyclic compounds. 1 For example, Stoltz reported the formation of cyclopentane-fused indoles from the 3-nonterminal-alkenyl indoles under the catalysis of Pd(II). 1h Widenhoefer used the platinum-catalyzed cyclization of 2-alkenylindoles to obtain the cyclohexane-fused indoles. 1i On the other hand, carbazole alkaloids are a class of ...
