An aqueous hemin-catalyzed, cyclodextrin-assisted NH insertion reaction of α-diazo ester into aromatic amines is described here. This aqueous catalytic system showed good compatibility with various arylamines, with yields up to 96%. A size-controlled reaction phenomenon by different cyclodextrins (CDs) was also observed when ethyl diazoacetate (EDA) was used. The reaction mechanism was also preliminarily
本文描述了α-重氮酯在含水血红素催化的环糊精辅助下的NH插入芳族胺的反应。该水性催化体系显示出与各种芳基胺的良好相容性,收率高达96%。当使用重氮乙酸乙酯(EDA)时,还观察到了由不同的环糊精(CD)引起的尺寸控制的反应现象。在设计的控制实验的基础上,还初步提出了反应机理。
