Asymmetric sulfoxidation catalyzed by a biomimetic manganese complex under continuous‐flow microreactor is described. The reaction is conducted in microreactor, it can rapidly (<4 min) oxidize a wide scope of sulfides with high yield (up to 91%) and excellent enantioselectivity (up to 99% ee), and allows shorter reaction times, easier scale‐up and lower catalyst loadings than its batchwise counterpart
描述了仿生锰配合物在连续流微反应器下催化的不对称硫氧化反应。该反应在微反应器中进行,可以快速(<4分钟)氧化多种硫化物,具有高收率(高达91%)和出色的对映选择性(高达99%ee),并允许更短的反应时间,更容易规模化-与分批反应相比,催化剂的负载量有所增加和降低。此外,还开发了一种方便的编号方法,用于放大不对称的亚砜基氧化反应,该方法可将反应直接放大至5 g,在20分钟内提供相应的亚砜。
