Complex polycyclic compounds resembling some natural alkaloids have been prepared in only three high yielding steps by combining the Ugi or Passerini multicomponent reactions with two metal-catalyzed cyclizations: an intramolecular Tsuji–Trost reaction of the isocyanide-derived amide followed by a ring-closing metathesis. Scaffold diversity may be explored by the appropriate choice of starting unsaturated isocyanides. The Tsuji–Trost cyclization proceeds with moderate to good diastereoselectivity, and the major diastereomer was in most cases isolated in the pure form. (Figure presented.).

Arylate then cyclize: A palladium(II)-catalyzed cascade sequence has been developed to provide highly diastereomerically enriched cis-1-aryl-3-vinyl isoindolines (see scheme). The method uses commercially available aryl boronic acids and boroxine compounds containing a variety of electron-rich, -neutral, or -poor aromatic groups. Ts=4-toluenesulfonyl. Copyright
