asymmetric total synthesis of the title compound 1, which is an important neurotransmitter, has been achieved. The synthesis features a metal-promoted, enantioselective ene reaction that provides entry into the kainic acid ring system from very simple precursors. Moreover, the zirconium-mediated Strecker reaction, which represents an outgrowth of earlier amide-to-imine methodology developed in our
[图:见正文]已经完成了重要的神经递质的标题化合物1的短而有效的不对称全合成。该合成具有金属促进的对映选择性烯反应,可从非常简单的前体进入海藻酸环系统。此外,锆介导的Strecker反应代表了我们实验室开发的较早的酰胺至亚胺方法的产物,证明了其出色的化学选择性和立体选择性。
