An additive-free enantioselective hydrogenation of β,β-disubstituted unsaturated carboxylicacids catalyzed by the Rh–(R,R)-f-spiroPhos complex has been developed. Under mild conditions, a wide scope of β,β-disubstituted unsaturated carboxylicacids were hydrogenated to the corresponding chiral carboxylicacids with excellent enantioselectivities (up to 99.3% ee). This methodology was also successfully
