Open sesame! A selective metal‐catalyzed ringopening of alkylidenecyclopropane derivatives leads to various functionalized acyclic derivatives possessing challenging quaternary stereocenters. The key feature of this transformation is that the ringopening is faster than the reductive elimination and is highly regioselective; a single ring‐opened product was always observed and the stereointegrity
