Amines are efficiently acylated by both cyclic and acyclic anhydrides by dissolving them in an aqueous medium with the help of a surfactant, sodium dodecyl sulfate (SDS). Cyclic and acyclic anhydrides react with equal ease with an amine, and amines with various stereo-electronic factors react at the same rates with an anhydride. Chemoselective acylation of amines in the presence of phenols and thiols
通过在表面活性剂十二烷基硫酸钠 (SDS) 的帮助下将胺溶解在水性介质中,胺被环状酸酐和无环酸酐有效地酰化。环状和无环酸酐与胺反应同样容易,具有各种立体电子因子的胺与酸酐以相同的速率反应。已经实现了在酚类和硫醇存在下胺的化学选择性酰化以及在酚存在下硫醇的化学选择性酰化。反应过程中不使用酸性或碱性试剂。分离酰化产物不需要色谱分离。在中性水性介质中反应,产物容易分离,副产物无害,使本方法成为一种绿色化学过程。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
