Synthesis of Nitrogen Heterocycles by a C-C Cross-Coupling/Cycloisomerization Strategy

The present article presents a personalized Account on the synthesis of nitrogen heterocycles by combination of regioselective Pd-catalyzed cross-coupling reactions of polyhalogenated heterocycles, i.e., Suzuki-Miyaura and Sonogashira reactions, with acid-mediated cycloisomerization reactions. In many cases, the products constitute new heterocyclic core structures and show interesting optical and electronic properties. 1 Introduction 2 Acridines 3 Phenathridines 4 Azapyrenes 5 Thienoquinolines 6 Pyrrolonaphthyridines 7 6-Aza-ullazines 8 Conclusions
