One-pot synthesis of 2-pyridones via chemo- and regioselective tandem Blaise reaction of nitriles with propiolates.
The Blaise reaction intermediate, generated in situ from Reformatsky reagent and nitrile, reacted with propiolates in a chemo- and regioselective manner to afford 2-pyridone derivatives in good to excellent yields.
