Synthesis of 1,5-Diaryl-Substituted 2-(2-Oxo-1,2-Dihydro-3-Pyrrol-3-Ylidene)Malononitriles

Key Points

• The research aims to synthesize previously unknown cyano-substituted derivatives of pyrrol-2-one with a 1,5-diaryl structure.
• Reactions of enamines with oxalyl chloride to create intermediate pyrrol-2,3-diones.
• Subsequent reactions of intermediate pyrrol-2,3-diones with malononitrile.
• Novel cyano-substituted derivatives of pyrrol-2-one were successfully synthesized.
• Final products demonstrated the incorporation of 1,5-diaryl fragments in their structure.
