Novel bis-(3-cyano-2-pyridones) derivatives: synthesis and fluorescent properties

Novel substituted bis-(3-cyano-2-pyridone) derivatives were prepared via a powerful method using enaminonitriles push–pull dienes as key building blocks. The synthesis was performed in three steps from easily accessible starting materials good yields. All target products structurally elucidated by spectroscopic data. reaction mechanism for formation of bis (3-cyano-2-pyridone) proposed. structures 3a and bis-pyridones 4c confirmed single-crystal X-ray diffraction. florescent study some (3-cyano-2-pyridones) reported.
