Abstract
The synthesis of ethyl -benzoyl-1-ethenyl)amino-3-dimethylaminopropeno ate (4) from benzoylacetone (1) via 3-dimethylaminomethylenebenzoylace tone (2) and ethyl N-(2-acetyl-2-benzoy1-1-ethenyl)glycinate (3) and i ts transformation into 4-benzoyl-2-ethoxycarbonyl-3-methylpyrrole (9) is described. Cyclization of 4 into 9 represents a new synthesis of po lysubstituted pyrroles.
