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.
右氮杂酰胺类右旋杂芳族大环的立体选择性合成的特征在于铃木-宫浦交叉偶联中的C16-C18键形成和对偶非对映选择性Dieckmann型大环化是关键步骤。铃木-宫浦交叉偶联在钯-双氧络合物的催化下,收率最高。
