Gold-catalyzed difunctionalizations of o-alkynylbenzenesulfonamides with aryldiazonium salts are reported herein. Upon irradiation with the blue LEDs, benzosultam products were formed via aminoarylation accompanied by the release of N2. Without irradiation, aryldiazonium salts were engaged as efficient electrophiles, facilitating electrophilic deaurations of the vinyl-Au(I) intermediates, followed
本文报道了金催化的邻炔基苯磺酰胺与芳基重氮盐的双官能化。在用蓝色 LED 照射后,苯磺舒坦产物通过氨基芳基化形成,伴随着 N 2的释放。在没有辐照的情况下,芳基重氮盐作为有效的亲电试剂,促进乙烯基-Au(I) 中间体的亲电脱氢,然后互变异构化得到N-芳基取代的 α-亚氨基 ( E )-腙。6 -endo-dig和 5 -exo-dig环化的区域选择性非常好。
