The invention relates to 1,3-disubstituted-3-oxopropane-1-sulphonic acids and sulphonates and pure enantiomers thereof. The invention further relates to the use of enantiomerically enriched 1,3-disubstituted-3-oxopropane-1-sulphonic acids and sulphonates in the resolution of mixtures of enantiomers. The 1,3-disubstituted-3-oxopropane-1-sulphonic acids and sulphonates are, in particular, (substituted) 1,3-diphenyl-3-oxopropane-1-sulphonic acids and sulphonates. The 1,3-disubstituted-3-oxopropane-1-sulphonic acids and sulphonates are prepared by conversion of the corresponding α,β-unsaturated ketones with an alkali metal bisulphate.
