In short order: A copper‐catalyzed Friedel–Crafts‐type strategy has been developed for the title reaction. An iterative CH arylation strategy has also been demonstrated for the functionalization of anilines by sequentially delivering different aromatic groups to the para, ortho, and meta positions (see scheme, Bn=benzyl, Piv=pivaloyl).

A synthesis of the bioactive indolocarbazole alkaloid K-252c (staurosporinone) via a sequential C–H functionalisation strategy is reported. The route exploits direct functionalisation reactions around a simple arene core and comprises of two highly-selective copper-catalysed C–H arylations, a copper-catalysed C–H amination and a palladium-catalysed C–H carbonylation, which build up the structural complexity
