A silver-catalyzed cascade cycloaddition of aza-1,6-enynes, affording multifunctional succimide frameworks initiated by the arylsulfonyl radical addition, has been developed. This process shows mild reaction conditions, excellent structural selectivity, and broad functional group tolerance. In addition, the Z/E-isomers can be easily separated, which provides an efficient method for obtaining pure Z/E-configuration products.

银催化自由基级联磺化/环加成反应制备可分离的Z / E异构体的多功能琥珀酰亚胺

已经开发了银催化的氮杂-1，6-烯炔的级联环加成反应，提供了由芳基磺酰基自由基加成引发的多功能琥珀酰亚胺骨架。此过程显示出温和的反应条件，出色的结构选择性和广泛的官能团耐受性。另外，Z / E-异构体可以容易地分离，这提供了获得纯Z / E-构型产物的有效方法。
