## Abstract The Friedel‐Crafts alkylation of indoles with nitroacrylates could provide __α__‐ and __β__‐tryptophan nitro‐precursors, respectively, in moderate to good yields under Lewis acid catalysis. The diastereoselectivities of the reaction were enhanced by using 2‐substituted indoles. The alky
