Pyrido[3,2,1-jk]carbazoles 1, synthesized from carbazoles and alkyl- or arylmalonates, gave regioselective electrophilic substitution reactions at position 5 such as chlorination to 5-chloro derivatives 2, nitration to 5-nitro compounds 3, or hydroxylatio

4-Hydroxy-5-phenylpyrido[32,1-jk]carbazol-6-ones (4, 5), which were obtained from carbazoles 1 and malonates 2 or 3, were converted to reactive intermediates such as 4-chlorides 9 or 4-tosylates 10, which gave in turn 4-azido-5-phenyl derivatives 11.5-Alkyl-4-azides 11 were not obtained in this manner; however a new one-pot azidation reaction was developed starting from 4-hydroxy derivatives 4 which gave azides 11 in good yields. 4-Azido-5-phenyl derivative 11f cyclized on thermolysis to the indole 12. The thermal behaviour of the azides 11 was studied by thermoanalytical methods (DSC).
