Abstract
Thermal cyclisation of 2-azido-3-(carbazol-3-yl)propenoic esters produces t he 1,6-dihydropyrrolo[3,2-c]carbazole and not the 1,9-dihydropyrrolo[2,3-b] carbazole whereas, in the case of the 4-methylcarbazolyl derivative, the 1, 9-dihydropyrrolo[2,3-b]-carbazole is formed in preference to the alternativ e pyrido[4,3-c]carbazole.
