general and highly efficient method for the synthesis of dl-2,3-diamide-1,4-diones via autoxidative dehydrogenative homocoupling of N-acyl-2-aminoacetophenones mediated by t-BuOK. The transformation is mild, operationally simple, and environmentally friendly. Control experiments and stereochemical results suggest that the substrate undergoes autoxidation followed by a diastereoselective SN2 reactopm.
我们在此报告了一种通用且高效的方法,用于通过由t -BuOK 介导的N-酰基-2-氨基苯乙酮的自氧化脱氢同源偶联来合成dl -2,3-diamide-1,4- diones。改造温和、操作简单、环保。对照实验和立体化学结果表明,底物发生自氧化,然后发生非对映选择性 S N 2 反应。
