in a Michael addition promoted oxidative domino three‐component reaction under heterogeneous conditions. This multicomponentreaction sequence led to the development of a general synthesis of highlyfunctionalized pyridines (see scheme), allowing selective and simultaneous incorporation of a substituent at the 4‐position and a synthetically useful functionality at the strategic 2‐position.
user‐friendly oxidative dualheterogeneous catalytic system capable of promoting polysubstituted pyridines as unique products from simple activated Michael acceptors, 1,3‐dicarbonyls and ammonium acetate. This metal‐free environmentally‐respectful and totally regioselective domino reaction proved to be a great strategy to access bi‐ and triaryl‐type pyridines as well as challenging bi‐ and triheteroaryl‐type
