enols/ketones has been achieved using either Hendrickson reagent in combination with triflic anhydride or triflic acid, which provides an efficient protocol for the divergent synthesis of polysubstituted indoles with flexible substituent patterns from α-arylamino-β-hydroxy-2-enamides, α-arylamino-β-oxo-amides or their enol-keto tautomeric mixture.
