Thermolysis of 3-Azidophenalen-1-ones to Naphtho[8,1-ab]carbazolones and Naphtho[8,1-ab]-8a-azonia-9-λ2-azafluoren-7-ones [1]

3-Azido-1-phenalenones 4 with aryl- or hetarylsubstituents in position 2 cyclized by thermolysis to give naphtho[8,1-ab]carbazolones 5 or naphtho[8,1-ab]-8a-azonia-9-λ2-azafluorenones 7. Reduction of the azides 4 gave the corresponding amino de
