中文摘要：

运用新方法来构筑季碳中心,即钯催化的多官能团羰基邻位芳基化反应与Tsu ji-Trost反应的串联反应.运用该方法,从商品化原料出发经9步反应完成了番杏碱（±）-M esembrine的形式合成.

英文摘要：

In this article, we apply a new method for the generation of quaternary palladium -catalyzed sequential arylation and allylic alkylation of highly functionalized carbon centers through a ketones. The use of our methodology culminated in the formal total synthesis of Aizoaceae alkaloids, namely, （ ± ） - Mesembrine in 9 steps from commercial materials.
