摘要
2-Pyridones, 2-quinolinones, and 1-isoquinolinones are critical building blocks in medicinal chemistry. These N-heterocycles, however, remain a challenge to synthesize by current methods. A mild, general, and efficient approach for the synthesis of these hydroxyl N-heteroarenes was developed by employing bromotripyrrolidinophosphonium hexafluorophosphate (PyBroP) as an activating agent and sodium acetate/water as the base/nucleophile combination. The reaction mechanism, especially the dual function of sodium acetate as the base and nucleophile, has been proposed on the basis of results from isotopic labeling experiments.
