An efficient synthesis of α-amidoketone derivatives through the cascade reactions of carboxylicacids with vinyl azides is presented. Compared with literature protocols, notable features of this new method include catalyst-free conditions, broad substrate scope, good tolerance of a wide range of functional groups, and high efficiency. In addition, the synthetic potential of this method as a tool for
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。

The present invention provides a novel compound that increases KAI1 promoter activity, a pharmaceutically acceptable salt thereof, and a composition for inhibiting cancer metastasis and invasion or treating colorectal cancer containing the same.
This paper shows a novel oxidative functionalization of α-amino ketones to yield the corresponding α-ketoamides and α-acylimidates. The reaction proceeds via oxygen delivery from water/alcohols in conjunction with an electron acceptor and 4-dimethylaminopyridine (DMAP). Mechanistic study indicates that DMAP exhibits a dual function of nucleophilic catalysis and proton abstraction.
