Various primary amides have been synthesized using the transamidation of various tertiary amides under metal-free and mild reaction conditions. When (NH4)2CO3 reacts with a tertiary amide bearing an N-electron-withdrawing substituent, such as sulfonyl and diacyl, in DMSO at 25 °C, the desired primary amide product is formed in good yield with good funcctional group tolerance. In addition, N-tosylated
在无金属和温和的反应条件下,使用各种叔酰胺进行转酰胺作用,可以合成出各种伯酰胺。当(NH4)2CO3在25°C的DMSO中与带有N吸电子取代基的叔酰胺(如磺酰基和二酰基)反应时,可以形成具有良好官能团耐受性的高收率的所需伯酰胺产物。另外,N-甲苯磺酸化的内酰胺衍生物通过开环反应提供了它们相应的N-甲苯磺酰胺基烷基酰胺产物。
