This study discloses assembling methods using 2-azidoacrylamides with a nucleophilic amino group. Divergent transformations of the amine-type trivalent platform resulted in a wide range of 2-azidoacrylamides involving a fluorosulfonyl group. Consecutive click conjugations, including triazole formation, thiol-ene-type 1,4-addition, and SuFEx reactions, efficiently assembled easily available simple modules.
Assembling methods using 2-azidoacrylamides having a nucleophilic amino group are disclosed. Divergent transformations of the amine-type trivalent platform were accomplished with a wide variety of electrophiles to obtain a broad range of 2-azidoacrylamides involving a fluorosulfonyl group-containing trivalent platform. Consecutive click conjugations including triazole formation, thiol-ene-type 1,4-addition, and SuFEx reactions realized the efficient assembly of easily available simple modules.
