yl)oxyl (TEMPO) in the presence of ruthenium photoredox catalysis is reported. The key transformation entails a highly efficient photoredox catalytic cycle using Hantzsch ester as a reductant. The ensuing alkoxyamine can be readily converted to the corresponding alcohol in one pot, representing an alternative approach to access aliphatic alcohols under photoredox conditions.
报道了在钌光氧化还原催化下,脂肪族羧酸衍生物与(2,2,6,6-四甲基哌啶-1-基)氧基(TEMPO)的脱羧氨氧基化反应。关键的转变需要使用Hantzsch酯作为还原剂进行高效的光氧化还原催化循环。随后的烷氧基胺可以很容易地在一个罐中转化为相应的醇,代表了在光氧化还原条件下接触脂肪族醇的另一种方法。
