Styryl azides, /,/-disubstituted

Disubstituted indoles have been prepared by rhodium carboxylate-catalysed reactions of jS,jS-disubstituted styryl azides (Scheme 145). ... [Pg.527]

A sizable number of reports describe carbocationic chemistry initiated by transition metal catalysts. This includes a variety of cyclization and ring-opening transformations. For example, a Rh2(II)-catalyzed synthetic method has been developed as a means of preparing 2,3-disubstituted indoles from styryl azides (Scheme 30)7 The chemistry... [Pg.299]

Rh2(II)-carboxylate complexes have been reported to promote the selective migration of aminomethylenes in )5,)5-disubstituted styryl azides to form 2,3-disubstituted indoles with stepwise migration before diffusion of the iminium ion (Scheme 155). ... [Pg.577]
