Novel approach to the synthesis of enantioenriched sulfoxides. Highly diastereoselective alkylation of sulfenate anions with 1,4-asymmetric induction.

Ketene aminothioacetals 2a−c and 5a−b bearing an enantiopure vinylic alkylsulfinyl substituent were readily prepared from (R)-2-cyclohexylsulfinyl-N,N-dimethylethanethioamide 1 with full control of the geometry of their double bonds. They underwent a Claisen rearrangement upon heating at THF reflux to afford α-sulfinyl γ-unsaturated thioamides 3a−c and 6a−b. With all substrates the asymmetric induction of the sulfinyl group was excellent. The determination of the absolute configurations of thioamides 3a−c and 6a−b was achieved either by X-ray crystallographic analysis or by chemical correlation. The stereochemical course of this [3,3] sigmatropic transposition was explained by an electronic model. Interestingly the Claisen rearrangement of the (ZE)-cinnamyl substrates 5b was shown to proceed through a boat transition state rather than a chair transition state; such a preference is quite unusual for acyclic systems.
