Abstract A chiral Brønsted acid‐catalyzed synthesis of axially alkenes was developed via an enantioselective and para ‐selective Friedel–Crafts reaction between phenols 1‐alkynylnaphth‐2‐ols. This methodology features efficient hydroarylation with high functional group tolerance, complete ‐selectivity, excellent yields (up to 99%), enantioselectivities 94% ee) in the presence a N ‐triflylphosphoramide catalyst. DFT calculations were performed investigate ‐selectivity results indicate that both kinetics thermodynamics parameters are more favorable compared ortho ‐selectivity.
