established, asymmetric hydrogenation of challenging tetrasubstituted α,β‐unsaturatedcarboxylicacids is rarely reported. We demonstrate enantioselective hydrogenation of cyclic and acyclic tetrasubstituted α,β‐unsaturatedcarboxylicacids via cobalt(II) catalysis. This protocol showed broad substrate scope and gave chiral carboxylicacids in good yields with excellent enantiocontrol (up to 98 % yield and
