An account of our previously disclosed total synthesis of the aryltetralin lignan natural product podophyllotoxin, a building block used in the synthesis of the FDA-approved anticancer drug etoposide, is disclosed. A C–H activation disconnection was viewed as being amenable to the preparation of E-ring modified analogs but proved challenging to execute. Various insights into palladium-catalyzed C–H
公开了我们先前公开的芳基四氢木脂素天然产物鬼臼毒素的全合成的信息,鬼臼毒素是在FDA批准的抗癌药物依托泊苷的合成中使用的结构单元。AC-H激活断开被认为适合于制备E环修饰的类似物,但执行起来却具有挑战性。报道了对复杂骨架上钯催化的CH芳基化反应的各种见解,最终导致了该策略的实施以及通过半合成手段无法获得的化合物的合成。
