Abstract:
Propylphosphonic acid anhydride has been successfully used as a coupling agent in the synthesis of a series of indolizine-2-carboxamido derivatives from indolizine-2-carboxylic acid and its 3-acetylated analogue. The acid substrates were obtained by saponification of the corresponding methyl esters produced, in turn, selectively and efficiently, by time-controlled cyclisation of a single Morita–Baylis–Hillman adduct. Various amino and hydrazino compounds with medicinal potential have been used to prepare indolizine-2-carboxamido and hydrazido derivatives.

Abstract:
A concise and efficient strategy has been proposed to synthesize indolizine derivatives from easily available aryl or heteroaryl methyl ketones, pyridines, and acrylonitriles. The mechanistic pathway involved the integration of iodination, pyridinium ylide synthesis, and 1,3-dipolar cycloaddition. The protocols were found to be highly efficient in terms of high yields, operational simplicity, mild reaction conditions, and easy workup. This method has provided an important supplement for the synthesis of indolizine derivatives via a novel tandem synthesis.
