报道了(+)-聚集蛋白E的首次全合成和(+)-聚集蛋白B的新全合成。我们的合成方法的主要特点包括钯催化的旋光性醋酸丙酯的环化-甲氧基羰基化和Suzuki-Miyaura偶联或cuc介导的偶联反应。提出了(+)-聚合体E (5R, 5s)的绝对构型。
The first total synthesis of (+)-gregatin E and a new total synthesis of (+)-gregatin B are described. Key features of our synthetic approach involve a palladium-catalyzed cyclization-methoxycarbonylation of optically active propargylic acetate and a Suzuki-Miyaura coupling or CuTC-mediated coupling reaction. The absolute configuration of (+)-gregatin E (5R,5'S) is proposed.
