ortho-quinols could be obtained in high yields (up to 99%) and enantioselectivities (up to 95:5 er). This methodology could be applied in the synthesis of bioactive lacinilenes in a gram-scale reaction. Based on the experimental investigations and previous work, a possible catalytic model was proposed.
使用N,N'-二氧化物-((III)络合物催化剂完成了用氧氮丙啶对萘的对映体选择性羟基化脱芳香化反应。各种取代的邻-quinols可以以高产率(高达99%)和对映选择性(高达95来获得:5 ER)。该方法可用于克级反应中的生物活性lacileilenes的合成。基于实验研究和先前的工作,提出了一种可能的催化模型。
