Abstract
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 lactone ring.
