Remote F effect : Unprecedented hetero‐Diels–Alder reactions of mono‐ and bis‐substituted cyclopentadienes have been realized by an asymmetric binary‐acid catalyst that synergistically combines a chiral phosphoric acid 1 h /InBr 3 with good periselectivity, high regioselectivity, and excellent stereoselectivity. Substituent mapping of the chiral phosphoric acid indicates a dramatic remote ortho ‐fluoro effect on the stereocontrol (see scheme).
