A common strategy for the stereoselective and protecting group-free total synthesis of the myxobacterial antibiotics myxothiazole Z, (14S)-melithiazole G and (14S)-cystothiazole F is described featuring an asymmetric organocatalytic transfer hydrogenation, a palladium-catalyzed Stille coupling and a cross-metathesis as the key steps.
本文介绍了一种通用的策略,该策略无需保护基团,实现了黏细菌抗生素myxothiazole Z、(14S)-melithiazole G和(14S)-cystothiazole F的立体选择性全合成。关键步骤包括不对称有机催化转移氢化、钯催化的Stille偶联反应以及交叉复分解反应。
