The total synthesis of lithospermic acid has been accomplished employing two CH activation reactions as key steps. Fe-catalyzed Cross-Dehydrogenative-Coupling reaction was used for the rapid construction of benzofuran framework. Pd-catalyzed ester-directed CH olefination allowed the efficient assembly of the dihydrobenzofuran ester and acrylate moieties.
使用两个C H活化反应作为关键步骤已完成了总精子酸的合成。铁催化的交叉脱氢偶联反应用于苯并呋喃骨架的快速构建。Pd催化的酯导向的C H烯化反应可有效组装二氢苯并呋喃酯和丙烯酸酯部分。
