A new synthetic route to functionalized imidazo[4,5-c]carbazoles (4) via intramolecular electrocyclization of indolo-1,3,5-hexatriene system (3a) is described. Thermally induced ring-closure of 2-ethylcarboxylate-(4-amino-5-imidazolyl)-3-indole (3d) led to the previously unknown imidazo[4,5-c]b-carb

The synthesis of the first example of a [1,4]diazepino [2,3-c]isoxazole derivative is reported. Reaction of an imidazo[4,5-c]isoxazole with acetylenic esters has been shown to lead to the formation of 2-pyrrol-2-yl imidazoles. Here we report an alternative reaction pathway in which the fused imidazo
