Time for SOme MOre: For the first time SOMO (singly occupied molecular orbital) activation has been exploited to allow a new approach to the α‐chlorination of aldehydes. This transformation can be readily implemented as part of a linchpincatalysisapproach to the enantioselective production of terminalepoxides.
SOme MOre 时间:首次利用 SOMO(单占据分子轨道)激活来实现醛的 α-氯化的新方法。这种转化可以很容易地作为对映选择性生产末端环氧化物的关键催化方法的一部分来实现。

In the course of our drug discovery programs, we had need to access chiral, 2-substituted thiomorpholines and their oxidized congeners, thiomorpholine 1,1-dioxides. Here, we disclose a high-yielding, general protocol for the enantioselective synthesis of C2-functionalized thiomorpholines and thiomorpholine 1,1-dioxides.
