We report the first examples of transition metal‐catalyzedenantioselective alkene hydroacylations with 1,1,2‐trisubstituted alkenes. DFT and mechanistic studies are consistent with a reaction pathway for these rhodium‐catalyzed processes including intramolecular alkene hydroacylation and α‐epimerization to generate highly enantioenriched, polycyclic architectures. This reaction sequence enables the
