A concise copper-catalyzed N-O bond cleavage/C-C/C-N bond formation procedure enables the synthesis of multisubstituted pyridines from various oxime acetates, activated methylene compounds, and a wide range of aldehydes. This method features inexpensive catalysts, no need for extra oxidant, and high step-economy.
