Walk on the same side! The title reaction occurs by means of highly stereospecific 1,3‐metal migration. The starting carboxylic acids are readily prepared by Birch reduction, and the developed protocol provides an efficient route to enantiomerically pure 5‐arylated‐1,3‐cyclohexadiene derivatives (see scheme).
