A photocatalyzed synthesis of 3‐sulfanylindolizines and 1,3‐bis(sulfanyl)indolizines was achieved starting from thiols and 2‐arylindolizines. Blue LED was used in the presence of an organic dye, eosin Y, as photocatalyst.
A sustainable electrochemical approach for site-selective C–H mono and bis-chalcogenation (sulfenylation or selenylation) of indolizine frameworks is described.
