A straightforward synthesis of magallanesine 1 from azetoisoquinoline 4 has been accomplished via [ 1.21~Meisenheimer rearrangement and an intramolecular Heck cyclization as the key reactions. Members of the plant family Berberidaceae have long been known to contain a number of alkaloids, and recent
