Acylsulfonamides can be rapidly and conveniently synthesized from a variety of carboxylic acids and sulfonamides utilizing the commercially available reagents, PS-DCC and DMAP under mild reaction conditions. DMAP can be efficiently scavenged by utilization of a silica-supported tosic acid cartridge (Si-SCX). In most of the cases studied, products with high purities and yields were obtained without
使用市售试剂PS-DCC和DMAP,可以在温和的反应条件下,从各种羧酸和磺酰胺快速方便地合成酰基磺酰胺。通过使用二氧化硅支撑的甲苯磺酸盒(Si-SCX),可以有效地清除DMAP。在大多数研究案例中,无需进一步纯化即可获得高纯度和高收率的产品。
