Stereoisomers of MeCH=CHSLi from Li/NH3 reduction of MeCH=CHSPr react with varying proportions of MsCl giving the respective stereoisomers of either bis(1-propenyl) disulfide (1), S-1-propenyl methane-sulfonothiate (2a), or 6-ethyl-4,5,7-trithiadeca-2,8-diene (3); oxidation of 3, a shallot oil component, gives 6-ethyl-4,5,7-trithiadeca-2,8-diene 7-oxide (cepaene, 4), an antithrombotic compound from onion.
