A stereoselective formal synthesis of a 16-membered antibiotic macrolide (-)-A26771B is described starting from (R)-propylene oxide and (+)-diethyl tartrate. Key steps involved in this alkyne-assisted convergent approach are alkyne zipper reaction, Cadiot-Chodkiewicz coupling, and Yamaguchi macrolactonization.
描述了从 (R)-环氧丙烷和 (+)-酒石酸二乙酯开始的 16 元抗生素大环内酯 (-)-A26771B 的立体选择性形式合成。这种炔烃辅助收敛方法涉及的关键步骤是炔烃拉链反应、Cadiot-Chodkiewicz 偶联和 Yamaguchi 大环内酯化。
