4-diarylpyrrole marine alkaloids has been developed using Hinsberg-type pyrrole synthesis and palladium-catalyzed Suzuki cross-coupling of the 3,4-dihydroxypyrrole bis-triflate derivatives as key reactions. Based on this approach, formal syntheses of permethyl storniamide A and ningalin B, and a total synthesis of lamellarin G trimethyl ether have been achieved.
使用Hinsberg型吡咯合成和钯催化3,4-二羟基吡咯双三氟甲磺酸酯衍生物的Suzuki交叉偶联,已经开发出一种高效的3,4-二芳基吡咯海洋生物碱途径。基于这种方法,已经实现了全甲基间苯二甲酰胺A和宁格灵B的正式合成,以及层状蛋白G三甲基醚的全合成。
