was developed by intermolecular copper-catalyzed reactions of diazoacetamides with aromatic and heteroaromatic thioamides bearing a pyrrolidine moiety. The direction of the reaction can be switched toward 2-amino-2-heteroarylacrylamides by replacing the pyrrolidine with an aniline group or by the use of 2-cyano-2-diazoacetamides. The proposed mechanism and DFT calculations allowed us to rationalize the
通过重氮乙酰胺与带有吡咯烷部分的芳族和杂芳族硫代酰胺的分子间铜催化反应,开发了一种新的类卡宾介导的硫代异戊二烯酮方法。通过用苯胺基团取代吡咯烷或使用 2-氰基-2-重氮乙酰胺,可以将反应方向转向 2-氨基-2-杂芳基丙烯酰胺。所提出的机理和 DFT 计算使我们能够合理化取代基对反应方向的影响。基于广泛的具有相似结构的可用试剂,发现了用于合成以前未知的 2-杂芳基硫代异构酮和 2-杂芳基丙烯酰胺的有效方法。一些合成的硫代异构酮在固态和溶液中表现出多色荧光。
