49_45/2010Cover Picture: Palladium-Catalyzed Coupling of Aldehyde-Derived Hydrazones: Practical Synthesis of Triazolopyridines and Related Heterocycles (Angew. Chem. Int. Ed. 45/2010)

Pharmaceutically active compounds ... ... and their intermediates require selective, efficient, and robust syntheses that utilize green chemistry principles. In their Communication on page 8395 ff., O. R. Thiel, M. Achmatowicz, and co-workers describe a two-step procedure involving selective palladium-catalyzed carbon–nitrogen bond formation followed by a clean oxidative cyclization that affords access to a variety of bicyclic and tricyclic heteroaromatic scaffolds.
