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 yield (91%) and enantiomeric excess (98%). Methyl (R)-2-(cyclohexylsulfinyl)dithioacetate (98% ee) was obtained from chiral cyclohexyl methyl sulfoxide (99% ee).
