Aliphatic amines, oxygenated at remote positions within the molecule, represent an important class of synthetic building blocks to which there are currently no direct means of access. Reported herein is an efficient and scalable solution that relies upon decatungstate photocatalysis under acidic conditions using either H2O2 or O2 as the terminal oxidant. By using these reaction conditions a series
在分子内较远位置处被氧合的脂肪族胺代表了一类重要的合成构件,目前尚无直接接触的手段。本文报道的是一种有效且可扩展的解决方案,该解决方案依赖于使用H 2 O 2或O 2作为末端氧化剂在酸性条件下的分解钨酸盐光催化。通过使用这些反应条件,可以将一系列简单且无偏的脂肪族胺原料氧化为增值的酮产品。最后,利用原位LED辐照样品的NMR光谱法可监测反应的动力学,从而使反应直接转化为流动。
