  An iodine-mediated oxidative cyclization reaction between 2-(pyridin-2-yl)acetate derivatives and different alkynes has been developed, which provides regioselective and chemoselective syntheses of multiply substituted indolizines under modified reaction conditions. Plausible mechanisms have been proposed to explain the selective syntheses of indolizines. This protocol can be also applied to the stepwise

  catalyzed synthesis of indolizine-1-carboxylates through oxidative CC and CN bond formations by the reaction of 2-pyridyl acetates with alkynes and alkenes without metal, oxidant, and base. This procedure is compatible with a broad range of functional groups in both alkynes and alkenes with good yields. The reaction proceeds through a tandem CC bond formation followed by an intramolecular cyclization
