A novel C–N coupling of various arylamines with dialkyl azodicarboxylates under metal-free conditions for the rapid assembly of carbamates has been achieved. This established protocol features mild reaction conditions, simple operation, broad substrate scope, moderate to excellent yields and good tolerance of functional groups. Moreover, the potential synthetic utility of products was exemplified by
在无金属条件下,实现了各种芳胺与偶氮二甲酸二烷基酯的新型 C-N 偶联,以快速组装氨基甲酸酯。该方案具有反应条件温和、操作简单、底物范围广、产率适中至优异、官能团耐受性好等特点。此外,一系列有趣的化学操作证明了产品的潜在合成用途。
