A highly stereoselective synthesis of (−)-kainic acid has been achieved in 14 steps and >7% overall yield starting from inexpensive trans-4-hydroxy-l-proline. The key steps are diastereoselective enolate alkylation and cuprate substitution reactions.
从便宜的反式-4-羟基-1-脯氨酸开始,分14个步骤实现了(-)-海藻酸的高度立体选择性合成,总收率> 7%。关键步骤是非对映选择性烯酸酯烷基化和铜酸酯取代反应。
