Reaction of 1-indolylmagnesium iodidelo with the appropriate sulfonyldiene in benzene-ether (1: 1) at 0 "C resulted in a cycloaddition and after workup the teaahydrocarbazole product was isolated. Results from the reaction of a few 2-phenylsulfonyl 1,3-dienes are given in Table 1. In all cases only
