Functionalized pyrrole-pyrone ensembles have been synthesized in up to 87% yields by KOH/MeCN [4 +2]-cyclization of available acylethynylpyrroles with methylene active esters. The synthesized compounds, due to their potential rich chemistry, are rewarding building blocks for novel pyrrole-integrated complex molecules and promising precursors of medicine targeted compounds.
