sequential nucleophilic addition followed by an intramolecular cyclization of functionalized nitriles with arylboronic acids has been achieved, providing an efficient synthetic pathway to access structurally diverse isoquinolines and isoquinolones. This methodology has also been successfully applied to the total synthesis of the topoisomerase I inhibitor CWJ-a-5 (free base).
已经实现了钯催化的连续亲核加成,然后用芳基硼酸进行分子内官能化腈分子内环化的第一个例子,从而提供了一种有效的合成途径,以获取结构多样的异喹啉和异喹啉酮。该方法也已成功应用于拓扑异构酶I抑制剂CWJ-a-5(游离碱)的全合成。
