مستخلص: A highlyenantioselective C2 Friedel–Crafts alkylation reactionof 3-substituted indoles to β,γ-unsaturated α-ketiminoesters has been developed. This reaction was efficiently catalyzedby a chiral phosphoric acid catalyst. The corresponding C2-substitutedindole derivatives, bearing an α-ketimino ester motif, wereobtained in moderate to high yields (up to 93%) and with high enantioselectivities(up to >99% ee).
