first example of organocatalytic enantioselective C–H insertionreactions of indoles and sulfoxoniumylides is reported. Under the influence of phosphoric acid catalysis, levels of enantiocontrol in the range of 20–93% ee and moderate yields (up to 50%) were achieved for 29 examples in formal C–H insertionreactions of free indoles and α-carbonyl sulfoxoniumylides. No nitrogen protection on the indole
