Abstract

An efficient synthesis of pharmacologically oriented, functionalized pyrrole-pyridone ensembles by the reaction of available acylethynylpyrroles with methylene active amides in almost quantitative yields has been implemented. The cyclocondensation proceeds smoothly at room temperature in a KOH/DMSO superbase suspension.
