formation of functionalized nitrones from N-hydroxyamides was reported. The reaction took place through two types of iridium-catalyzed reactions including dehydrosilylation and hydrosilylation. The method showed high chemoselectivity in the presence of sensitive functional groups, such as methyl esters, and was successfully applied to the synthesis of cyclic and macrocyclic nitrones, which are known to be
报道了 Ir 催化从 N-羟基酰胺还原形成官能化硝酮。该反应通过两种类型的铱催化反应进行,包括脱氢硅烷化和氢化硅烷化。该方法在敏感官能团(如甲酯)的存在下显示出高化学选择性,并成功应用于环状和大环硝酮的合成,已知这些化合物很难通过常规方法获得。(1) H NMR 研究强烈支持生成 N-甲硅烷氧基酰胺和 N,O-缩醛作为实际中间体。
