The one-pot HornerâWadsworthâEmmons/oxa-Michael cascade followed by spiroketalisation affords the tetracyclic benzannulated spiroketal core of berkelic acid, an extremophile natural product with selective activity against ovarian cancer.
一锅法的霍纳-瓦兹沃斯-埃门斯/氧桥-迈克尔级联反应 followed by spiroketal化反应,得到四环芳香化的螺旋酮核心,即伯克利酸,这是一种对卵巢癌具有选择性活性的极端嗜好者天然产物。
