AB A straightforward and efficient synthesis of the two less explored types of indolocarbazoles has beendeveloped. Two different processes for the carbazole nucleus preparation, a gold-catalysed regioselectivecyclization followed by the dioxomolybdenum-catalysed version of Cadogan reductive cyclization,enables the sequential construction of two carbazole cores. The procedure features total regioselectivityand high overall yields. The required starting α-indol-3-ylalkyl propargylic alcohols are easily and efficientlyaccessed from commercially available reagents. In addition, the photoluminescent properties of twoindolo[2,3-c]carbazoles, with fluorescence quantum yields around 0.7, have been studied.
