The sulfone functional group has a strong capacity to direct the asymmetrictransferhydrogenation (ATH) of ketones in the presence of [(arene)Ru(TsDPEN)H] complexes by adopting a position distal to the η6‐arene ring. This preference provides a means for the prediction of the sense of asymmetric reduction. The sulfone group also facilitates the formation of a range of reduction substrates, and its

Epichlorohydrin and glycidol are transformed in a four step sequence into β-dimethylamino-α-phenylthio-substituted α,β-unsaturated carbonyl compounds 5, possessing differently O-protected oxymethyl substituents at the carbonyl group. These compounds are of value as intermediates in inverse-type hetero-Diels-Alder reactions.
