A new approach to the synthesis of the first C-phosphorylated pyrrol-2(5H)-one is developed. Direct reaction of 3,4-dichloropyrrol-2(5H)-one with P-nucleophiles fails to give the desired compounds. This fact was explained on the basis of quantum-chemical calculations of the pyrrol-2(5H)-one structures. © 1996 MAEe cyrillic signK Hayκa/Interperiodica Publishing.
