The first total synthesis of (±)-γ-indomycinone (2) has been accomplished starting from juglone (5) in nine steps, including Diels–Alder reaction of 5 and diene 6 and the formal 6-endo-dig cyclization of alkynone 3 as the key steps.
(±)-γ-
吲哚霉素酮 (2) 的首次全合成以
胡桃醌 (5) 为起始点,分九个步骤完成,包括 5 和二烯 6 的 Diels-Alder 反应以及炔酮 3 的正式 6-endo-dig 环化作为关键步骤。
