A reaction of hexafluoro-1,4-naphthoquinone with 2-aminopyridines

A reaction of hexafluoro-1,4-naphthoquinone with 2-aminopyridines leads to fluorinated naphtho[1',2':4,5]imidazo[1,2-a]pyridine-5,6-diones. Advantages of the proposed one-step procedure are easily available starting materials, atom economy, and simple isolation of products without chromatographic purification.
