The first asymmetric total synthesis and stereochemical assignments of 10-membered macrolactones relgro and 10'-oxorelgro are disclosed. To this end, palladium-catalyzed Stille coupling, the Mitsunobu reaction, ring-closing metathesis, EDCI promoted coupling and the Jacobsen hydrolytic kinetic resolution are used as key steps. The total synthesis followed by thorough evaluation of the optical rotation
公开了10元大内酯relgro和10'-氧杂睾酮的第一不对称全合成和立体化学分配。为此,关键步骤是使用钯催化的Stille偶联,Mitsunobu反应,闭环复分解,EDCI促进的偶联以及Jacobsen水解动力学拆分。总合成之后,对旋光度和CD光谱数据进行了全面评估,从而改变了relgro和10'-oxorelgro的C-6'绝对构型。此外,relgro首次报道了1H和13C NMR数据。
