A concise synthesis of (+)-allosedamine has been achieved using cobalt-catalyzed hydrolytic kinetic resolution (HKR) and ruthenium-catalyzed ring closing metathesis (RCM) as two key steps, in which HKR was used to introduce both stereogenic centers in the natural compound with a high degree of diastereomeric ratio and cyclization was carried out with the well developed RCM procedure.
使用钴催化的水解动力学拆分(HKR)和钌催化的闭环复分解(RCM)作为两个关键步骤,已经实现了(+)-allosedamine的简明合成,其中HKR用于在自然界中引入两个立体异构中心。具有高度非对映异构体比例和环化作用的化合物,是通过完善的RCM方法进行的。
