Nortopsentins A-D, antifungal 1, 4-bisindolylimidazole marine alkaloids isolated from a sponge, were synthesized through palladium-catalyzed cross-coupling of 3-indolylboronic and 6-bromo-3-indolylboronic acids with halogenoimidazoles as the key reaction.
以卤代咪唑为关键反应,通过钯催化 3-吲哚硼酸和 6-溴-3-吲哚硼酸的交叉偶联合成了从海绵中分离出的抗真菌 1,4-双吲哚基咪唑海洋生物碱 Nortopsentins A-D。
