Fluorescent 2‐Hydroxy‐3‐(pyridin‐2‐yl)‐4H‐quinolizin‐4‐ones through Dimerization of Pyridineacetic Acids

Pyridineacetic acids undergo dimerization under action of the activating agents, giving rise to 2‐hydroxy‐3‐(pyridin‐2‐yl)‐4H‐quinolizin‐4‐ones. The introduction of a difluoroboryl bridge into such derivatives leads to novel highly fluorescent compounds. Borylated 2‐hydroxy‐3‐(pyridin‐2‐yl)‐4H‐quino...

Description
Summary:Pyridineacetic acids undergo dimerization under action of the activating agents, giving rise to 2‐hydroxy‐3‐(pyridin‐2‐yl)‐4H‐quinolizin‐4‐ones. The introduction of a difluoroboryl bridge into such derivatives leads to novel highly fluorescent compounds. Borylated 2‐hydroxy‐3‐(pyridin‐2‐yl)‐4H‐quinolizin‐4‐ones, promising fluorescent compounds, were obtained in just two steps form pyridineacetic acids through a dimerization reaction.
