Abstract

Stereoselective synthesis of the right-hand heteroaromatic macrocycle of diazonamide A features C16–C18 bond formation in the Suzuki–Miyaura cross-coupling and atropodiastereoselective Dieckmann-type macrocyclization as key steps. The Suzuki–Miyaura cross-coupling gave the best yields when it was catalyzed by a palladium–dioxygen complex.
