“…To collect additional information and to measure the impact of these variation points on the N-arylation step, five types of substrates (I-V) were designed and investigated. Significantly, scaffolds bearing various groups having different electron-withdrawing or electron-donating properties such as ester (2a,b;Type I), amide (2c-h; Type II), ether (3a), amine (3b,c) or retroamide (3d) belonging to the family of Type III, aryl (4, 5; Type IV), and finally some lactam vinylogues (6-10; Type V) were chosen and investigated (Scheme 1).…”
