Synthesis of some 5-oxoindolizine derivatives using ethyl pyrrolidin-2-ylideneacetate (1) and acyclic α,β-unsaturated carbonyl compounds is described.The structure of Michael adducts, intermediates for 5-oxoindolizines, obtained by treatment of 1 with dimethyl acetylenedicarboxylate or methyl propiolate are discussed.
