fragment of the amythiamicins by a Negishi cross‐coupling. For the synthesis of amythiamicinC, this step was followed by a Negishi cross‐coupling at C‐6 of the pyridine core. Subsequent attachment of the Eastern fragment was achieved by amide bond formation and macrolactam ring closure by a Stille cross‐coupling at C‐2. The Eastern bithiazole fragment of the amythiamins was constructed also by regioselective
