Employing anilines as nucleophiles in double carbonylation is a longstanding challenge. In this communication, a Mn(III)-promoted double carbonylation of alkylborates or Hantzsch esters with anilines toward the synthesis of α-ketoamides has been developed. By using easily available potassium alkyltrifluoroborates or Hantzsch esters as the starting material, and cheap and non-toxic Mn(OAc)3 ⋅ 2H2O as
在双羰基化中使用苯胺作为亲核试剂是一个长期的挑战。在本次交流中,已经开发了一种 Mn(III) 促进的烷基硼酸盐或 Hantzsch 酯与苯胺的双羰基化,用于合成 α-酮酰胺。通过使用容易获得的烷基三氟硼酸钾或 Hantzsch 酯作为起始材料,并以廉价且无毒的 Mn(OAc) 3 · 2H 2 O 作为促进剂,以中等至良好的收率合成了范围广泛的烷基α-酮酰胺衍生物。优良的选择性。
