We found that PLE can be used as an efficient catalyst for desymmetrization of prochiral tertiary amine N-oxides and demonstrated that they were hydrolyzed by PLE efficiently to afford N-chirogenic tertiary amine oxides up to 99% ee in moderate to good yields.
我们发现PLE可以用作手性叔胺N-氧化物去对称化的有效催化剂,并证明PLE可有效地将它们
水解,以中等至良好的收率提供高达99%ee的N-色
氨酸叔胺氧化物。
