A library of novel chiral biphenol-based diphosphinite (BOP) ligands was designed and created. These BOP ligands were applied to a Pd-catalyzed intermolecular allylic etherification reaction, which provided a key intermediate for the formal total synthesis of (−)-galanthamine with 97% ee in 97% yield.
设计并创建了一种新颖的基于手性双酚的二亚膦酸酯(BOP)配体的库。这些BOP配体被应用于Pd催化的分子间烯丙基醚化反应,该反应为(97)ee的97%收率的(-)-加兰他敏进行正式的全合成提供了关键的中间体。
