Photoredox-catalyzed synthesis of sulfonated oxazolines from N-allylamides through the insertion of sulfur dioxide

Photoredox-catalyzed generation of sulfonated oxazolines starting from N -allylamides, DABCO·(SO 2 ) 2 , and aryldiazonium salts has been developed and a range of sulfonated oxazolines were obtained in moderate to good yields.
