An efficient convergent synthetic route to construct the HIJ-ring system of ciguatoxin was achieved via stereo controlled eight-membered ring formation by using acetylene cobalt complex and subsequent six-membered ring formation through intramolecular 1,4-addition reaction.
利用乙炔钴络合物通过立体控制形成八元环,随后通过分子内 1,4 加成反应形成六元环,从而实现了构建雪卡毒素 HIJ 环系统的高效聚合合成路线。
