Lost in rotation: the concise strategy of the first enantioselective total synthesis of bismurrayaquinone A utilized traceless stereochemical exchange to form an enantioenriched biphenyl core that was elaborated in a bidirectional manner to the natural product. Observed racemization on an unsuccessful initial route prompted studies into the configurational stability of bismurrayaquinone A and related biquinones.
首次对双木脂素 A 的对映选择性全合成采用简洁的策略,利用无痕迹的立体化学交换形成手性富集的联苯核心,然后以双向方式对天然产物进行修饰。在最初的不成功路线上观察到的外消旋化促使对双木脂素 A 和相关的倍半木脂素的构型稳定性进行研究。
