Synthesis and Spectrophotometric Analysis of 1-Azafluorenone Derivatives

Synthesis and Spectrophotometric Analysis of 1-Azafluorenone Derivatives

A new extension for the ‘one pot’ construction of diverse 1-azafluorene derivatives featuring a Diels–Alder/retro-Diels–Alder cycloaddition is reported. Conditions were also determined for oxidation to the derived azafluorenones. The spectrophotometric analysis of five different azafluorenones were...
