“…14 Notably, the use sulfamidate 15 , a cyclic N-sulfonylimine, has been used to prepare interesting heterocyclic scaffolds. Sulfamidate is transformed into a fused heterocycle using a Michael addition 16 , cycloaddition [17][18][19][20][21][22] , arylation [23][24][25] , alkenylation [26][27][28] , or alkynylation 26 strategy by leveraging electrophilicity of cyclic N-sulfonylimines (Scheme 1). Scheme 1: Strategy to explore N-sulfonylimine reactivity towards multicomponent reaction However, among reported synthetic strategies, construction of direct C-C bond between the imine carbon and the (het)aromatic partner is underrepresented in the literature.…”
