A short and flexible asymmetric synthesis of ramariolides A and C was accomplished. A bimetallic catalytic system consisting of Pd–Cu-mediated cascade cyclization, unprecedented Z–E isomerization by a Ru-based metathesis catalyst, and late-stage stereoselective epoxidation are the key steps involved in the synthesis.
完成了短而灵活的雷莫拉利利德A和C的不对称合成。由Pd-Cu介导的级联环化,Ru基的复分解催化剂进行前所未有的Z - E异构化以及后期的立体选择性环氧化组成的双金属催化系统是合成过程中的关键步骤。
