The total synthesis of racemic γ-indomycinone (rac-3) was achieved by Baker–Venkataraman rearrangement of ester 11 to the diketone 12, acid-catalyzed cyclization to the anthrapyranone 13, followed by methyl ether cleavage and acetylation to 16, selective bromination of the branched side chain with simultaneous SN1-type hydroxy substitution to 23 and transesterification to rac-3. The corresponding γ-indomycinone
外消旋 γ-吲哚霉素 (rac-3) 的全合成是通过将酯 11 重排为二酮 12、酸催化环化为蒽酮 13、然后甲基醚裂解和乙酰化为 16、选择性溴化支链侧链同时 SN1 型羟基取代为 23,酯交换为 rac-3。相应的 γ-吲哚霉素 11-甲基醚 (rac-20) 以类似的反应顺序制备。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
