The seco-acid derivative designed by conformation calculation and lactonization experiment of model seco-acids was synthesized, and subjected to macrolactonization to afford the lactone derivative. The lankanolide was synthesized via several steps after the lactonization, and the synthetic lankanolide was confirmed to have the same physical data (NMR, mass, IR and αD) as the lankanolide prepared from
该开环通过模型的构象计算和实验内酯设计-酸衍生物开环-acids合成,并进行macrolactonization,得到内酯衍生物。内酯化后,通过多个步骤合成了兰卡洛尼,并证实合成的兰卡洛尼具有与根据报道的方法从兰卡霉素制备的兰卡洛尼相同的物理数据(NMR,质量,IR和αD)。
