Description
Summary:The catalyst and additive‐free, photo‐driven cross dehydrogenative coupling (CDC) reaction initiated by electron donor‐acceptor (EDA) complexes between electron rich indolizines and electron poor quinones has been demonstrated. This green transformation reveals the advantages of operational simplicity, mild reaction conditions and good functional group tolerances. A visible light‐promoted, operationally simple, and mild reaction to construct functionally important derivatives of indolizine was developed. Interestingly, this photo‐driven CDC transformation can go ahead without adding any photocatalyst or additive. In place of catalyst, the formation of EDA complex between indolizine and quinone drives this photochemical reaction.
