The addition reaction of the sodium α-sulfinyl carbanion of a racemic aryl dichloromethyl sulfoxide to (-)-menthone in the presence of boron trifluoride diethyl etherate gave an adduct as a mixture of two easily separable diastereomers. After separation of the diastereomers, they were each treated with sodium hydride to afford enantiomerically pure aryl dichloromethyl sulfoxides and (-)-menthone both in high yields. This procedure provides a simple and efficient method for the resolution of racemic aryl dichloromethyl sulfoxides.
Asymmetric Synthesis of α,α-dichlorosulphoxides from Substituted Thioacetates and Sodium Hypochlorite in β-Cyclodextrin Complexes

The reaction of β-cyclodextrin complexes of substituted thioacetates (1) with sodium hypochlorite in aqueous medium gives optically active α,α-dichlorosulphoxides (2) in good yields with an enantiomeric excess (e.e.) of up to 53percent.
