A total synthesis of (+)-brefeldin C (BFC) and two brefeldin A (BFA) analogues - (+)-nor-Me BFA and (+)-4-epi-nor-Me BFA - has been developed. Key features of the syntheses include desymmetrization of meso anhydrides, a Carreira reaction to control the absolute configuration at C4 of BFC, a Suzuki-Miyaura cross-coupling reaction to create the C11-C12 bond and a Yamaguchi reaction to form the 13-membered
(+)-brefeldin C (BFC) 和两种 brefeldin A (BFA) 类似物 - (+)-nor-Me BFA 和 (+)-4-epi-nor-Me BFA - 的全合成已经开发出来。合成的关键特征包括内消旋酐的去对称化、控制 BFC C4 绝对构型的 Carreira 反应、产生 C11-C12 键的 Suzuki-Miyaura 交叉偶联反应和形成 13 元内酯的 Yamaguchi 反应戒指。
