1,2:5,6-Di-O-isopropylidene-α-D-glucofuranosyl (S)-cyclohexanesulfinate

The first crystal structure of a chiral diacetone-D-glucose (DAG) sulfinate, C18H30O7S, is reported. The absolute configuration (S) of the S atom is assigned. Previous assignments of the stereochemistry of analogous DAG su

Asymmetric thio-claisen rearrangement induced by an enantiopure alkylsulfinyl group. Unusual preference for a boat transition state in the acyclic series

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 ?-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.

Synthesis of racemic and enantiopure 2-alkylsulfinyl dithioacetates and thioacetamides

New 2-alkylsulfinyl dithioacetates and thioacetamides have been prepared. The asymmetric synthesis of (R)-2-(cyclohexylsulfinyl)-N,N- dimethylthioacetamide from previously unreported (S)-diacetone-D-glucose cyclohexanesulfinate was achieved in excellent y
