Reported here is the reductive transamidation of tertiary amides with nitroarenes promoted by main group metal magnesium and chlorosilane. The reaction uses commercially available and air-stable nitroarenes as nitrogen sources, so it can occur under transition-metal- and ligand-free conditions, thus providing a step-economic and cost-effective strategy for forming centrally important secondary amides
这里报道的是在主族金属镁和氯硅烷促进下叔酰胺与硝基芳烃的还原转酰胺基化反应。该反应使用市售且空气稳定的硝基芳烃作为氮源,因此可以在无过渡金属和配体的条件下发生,从而为形成重要的仲酰胺提供了一步经济且具有成本效益的策略。通过镁促进的还原性转酰胺基化可以很容易地获得一些生物学上有趣的酰胺基序。
