(-)-Podophyllotoxin is one of the most potent microtubule depolymerizing agents and has served as an important lead compound in antineoplastic drug discovery. Reported here is a short chemoenzymatic total synthesis of (-)-podophyllotoxin and related aryltetralin lignans. Vital to this approach is the use of an enzymatic oxidative C-C coupling reaction to construct the tetracyclic core of the natural product in a diastereoselective fashion. This strategy allows gram-scale access to (-)-deoxypodophyllotoxin and is readily adaptable to the preparation of related aryltetralin lignans.
(-)-鬼臼毒素是最有效的微管解聚剂之一,它是抗肿瘤药物发现中的一个重要先导化合物。本文报道了(-)-鬼臼毒素及相关芳基四氢萘木脂素的短路线酶促全合成。该方法的关键是利用酶促氧化 C-C 偶联反应以非对映选择性方式构建天然产物的四环核心。该策略允许(-)-脱氧鬼臼毒素进行克级规模的制备,并且易于适应相关芳基四氢萘木脂素的制备。
