Flavin reduction is subsequently reversed through oxidation by molecular oxygen, resulting in hydrogen peroxide formation. We present a streamlined synthetic procedure for assembling the tetracyclic core structure of sulfur-bearing discorhabdin-type alkaloids. Success relies on the BF3Et2O-promoted dienone-phenol rearrangement/sulfur insertion cascade, a single-step transformation converting the readily available N,O-acetal-bridged tetracy
