  yield under microwave irradiation and the obtained yield was compared with the conventional synthesis method after column purification. Different novel 3-benzoyl indolizine derivatives were synthesized by microwave irradiation. The newly synthesized compound structures were characterized by spectral analysis such as 1H-NMR, 13C-NMR, and HRMS.

  A number of 3-acylated indolizines were synthesized in good to excellent yields by a newly established reaction between picolinium salts and the methylsulfate salt of A (R = Me), the adduct formed from DMF-Me2SO4 as the key reagent. The low cost, short reaction time, mild reaction condition, and easy purification of the products make this an attractive new method for the synthesis of indolizine compounds. A variety of functional groups (nitro, cyano, ester, methoxy, and halogens) were well tolerated under the reaction conditions. (c) 2007 Elsevier Ltd. All rights reserved.

  Among a number of DMF dialkyl acetals investigated for the regioselective synthesis of 3-acylindolizines, the di-t-butyl acetal, via its iminium intermediate readily formed in situ, provides the highest chemoselectivity for the intermolecular cyclization of picolinium salts. DMF di-i-butyl acetal was applied to the syntheses of a variety of 3-acylated indolizines including alkyl, aryl, and heteroaryl substituents. (c) 2006 Elsevier Ltd. All rights reserved.
