[GRAPHICS]A variety of functionalized N-alkoxyindole-3-carbonitrile derivatives are achieved under remarkably mild conditions by applying a FeCl3-mediated intramolecular heterocyclization of 3-alkoxyimino-2-arylalkylnitliles. This novel synthesis allows the N-moiety on the side chain to be annulated to the benzene ring as the final synthetic step, which enables the functionalization of the benzenoid portion of the indole at an early stage of the synthesis.

heterocyclization of the readily available 3‐alkoxyimino‐2‐arylalkylnitriles mediated by iodobenzene dichloride/zinc chloride. The mechanism of the reaction proposes the formation of a key intermediate of nitrenium cation from a chlorination and dechlorination process facilitated by the hypervalent iodine reagent and Lewis acid respectively.
