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.
重氮酰胺A右手杂芳族大环的立体选择性合成以铃木-宫浦交叉偶联中C16-C18键的形成和阻转非对映选择性迪克曼型大环化作为关键步骤。当由钯-双氧络合物催化时,铃木-宫浦交叉偶联的产率最高。
