The performance of various transition-metal catalysts was explored in the step-economical synthesis of naturally occurring lamellarin alkaloids by C–H/N–H activation. The oxidative alkyne annulation proceeded efficiently by using sustainable ruthenium(II) catalysis, which set the stage for a concise synthesis of lamellarin D, lamellarin H and derivatives thereof.
