Alternative synthetic methodology for the direct installation of sulfonamide functionality is a highly desirable goal within the domain of drug discovery and development. The formation of synthetically valuable N-sulfonyl imines from a range of aldehydes, sulfonamides, and PhI(OAc)2 under practical and mild reaction conditions has been developed. According to mechanistic studies described within, the reaction
用于直接安装磺酰胺功能的替代合成方法是药物发现和开发领域内的一个非常理想的目标。已经开发出在实用和温和的反应条件下从一系列醛、磺酰胺和 PhI(OAc)2 形成具有合成价值的 N-磺酰基亚胺。根据其中描述的机理研究,反应通过初始步骤进行,该步骤涉及自由基引发剂(由可见光或热产生)以激活反应底物。该反应提供了一种合成有用且操作简单、相对温和的替代方法,可替代使用稳定、广泛可用的试剂的 N-磺酰基亚胺的传统形成。
