Gold-Catalyzed Reaction of Indoles with Alkynes

5 Gold-Catalyzed Reaction of Indoles with Alkynes [Pg.113]

The formation of the sptro intermediate III-4 is suggested by the isolation of spiro compounds during the study of the reaction. Similar intermediates are probably involved in the 1-exo-dig cyclization. In this case, intermediates of type III-7 could be formed directly by a Friedel-Crafts-type reaction, or indirectly, by opening of cyclopropyl carbenes III-8 at C-C bond a (Fig. 4.6). [Pg.115]
