Iron-Catalyzed Aerobic Oxidation and Annulation Reaction of Pyridine and α-Substituted Allenoate toward Functionalized Indolizine.

An iron-catalyzed reaction of pyridine and α-substituted allenoate has been disclosed. The present strategy incorporates the aerobic oxidation into annulation involving substituted allenoate, thus providing a new access to functionalized indolizine.
