The current strategy features low-cost catalytic system, use of electron-rich olefins, operational simplicity, and broad substrate scope, thus providing a facile and efficient access to substituted pyridines in moderate to good yields. Key words Key wordsannulation - ketoxime acetates - N-acetyl enamides - pyridines - iron Full Text References References and Notes 1a Zhou Y, Zhu X, Zhang L, Tang C, Feng B. Chem. Biol.

Catal. 2021; 2: 237 13 General Procedure for the Synthesis of Pyridines In a sealed tube, ketoxime-enoates 1 (0.2 mmol, 1 equiv), N-acetyl enamides 2 (0.4 mmol, 2 equiv), and FeCl2 (0.02 mmol, 10 mol%) were mixed in DCE (2 mL) and stirred at 120 °C for 8 h. Upon completion of the reaction, the mixture was then allowed to cool down to room temperature and the reaction solution was concentrated under vacuum. The crude residue was purified by column chromatography (petroleum ether/ethyl acetate) on silica gel to give the corresponding pyridines 3.
