Condensation of 1-amino-4-azafluorene with α-diketones and α,β-unsaturated ketones

Condensation of 1-amino-4-azafluorene with α-diketones and with unsaturated ketones in basic medium gives novel substituted 1,4- diazafluoranthenes and also dihydro-4-azafluoreno[9,9a,1-b,c] cyclohexano[2′,3′-e]- and indano[1′,2′-e]azepines.
