  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

  We have discovered a new route to 3-acylated indolizine structures via iodine-mediated hydrative cyclization. Reaction mechanism is proposed for this novel transformation, which involves a 5-exo-dig iodocyclization, deprotonation, incorporation of another iodo group, deprotonation, and subsequent replacement of the diiodo group by H2O. Various 3-acylated indolizine derivatives were obtained using this mild procedure in good yields. (c) 2007 Elsevier Ltd. All rights reserved.
