carbonyl‐stabilised ammonium ylide‐mediated epoxidation reactions were systematically investigated by experimental and computational means and the hereby obtained energy profiles provide explanations for the observed experimental results. In addition, we were able to identify the first tertiary amine‐based chiral auxiliary that allows for high enantioselectivities and high yields for such epoxidation reactions.
通过实验和计算手段系统地研究了羰基稳定的铵叶立德介导的环氧化反应的关键因素,由此获得的能量分布为观察到的实验结果提供了解释。此外,我们还能够鉴定出第一个基于叔胺的手性助剂,该助剂可实现高对映选择性和高产率,用于此类环氧化反应。
