The total synthesis of soraphen A, a myxobacterial metabolite and inhibitor of acetyl CoA carboxylase, was completed in 11 steps (longest linear sequence), less than half the steps previously required. Seven metal-catalyzed processes were deployed to unlock step-economy (comprising five asymmetric processes and four C–C bond formations). The present route does not utilize chiral auxiliaries, and four
粘细菌代谢物和乙酰辅酶 A 羧化酶抑制剂 soraphen A 的全合成在 11 个步骤(最长的线性序列)中完成,不到以前所需步骤的一半。部署了七个金属催化过程来解锁步骤经济(包括五个不对称过程和四个 C-C 键形成)。目前的路线不使用手性助剂,五个 C-C 键形成中的四个利用非预金属化伙伴。为了最大化收敛性,使用 Pd-AntPhos 催化剂开发了不对称 Tsuji 还原,该催化剂允许复分解不活泼的烯丙基碳酸酯充当掩蔽的末端烯烃,从而实现连续的烯烃复分解事件。
