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

Polycyclic Compounds: Part I - Synthesis and Reactions of 2-Aryl-3-hydroxyphenalen-1-ones
The reaction of naphthalic anhydride (I) with arylacetic acids results in the formation of 3-hydroxy-2-arylphenalen-1-ones (IIa, IIb) and 3-arylmethylene-1H,3H-naphthopyran-1-ones (IVa, IVb).Complete spectral evidence in favour of structure (IIa)
