Abstract

3463 Angew. Chem. Int. Ed. 2006, 45, 3462–3465 2006 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim www. angewandte. org cyclization with a CÀH activation, leading to the heterocycles 16 a–c in 74–85% yield and demonstrating the broad scope of this type of ring closure (Scheme 4). In summary, we have reported new Pd-catalyzed cyclizations leading to condensed N-heterocycles. The key step of these ring closures is a chemoselective ...
