reagents with methyl dithioacetate give dithioacetals (or hemidithioacetals) resulting from a carbophilic addition process. Reactions with various allylic organomagnesium compounds always involve an “inversion” of the allylic chain and direct carbophilic addition, rather than initial thiophilic addition followed by [2.3] sigmatropic shift. Three methods for the synthesis of β-unsaturated ketones are described

Alkylation of delocalized anions resulting from metallation of N-phenyl thioimidoesters (precursors of dithioesters and thiolesters) takes place on nitrogen with “saturated” thioimidoesters (alkane thiomidates). On the contrary, unsaturated thiomidoesters (α or β-ethylenic, α-arylated) are regioselectively alkylated on the α carbon atom by alkyl or allylic halides. The possibilities for synthesis offered
THE HIGHLY SELECTIVE REACTION OF LITHIUM DITHIOESTER ENOLATES WITH β-ALKENYL-β-PROPIOLACTONES: A SIMPLE METHOD FOR THE SYNTHESIS OF 6-(METHYLTHIO)THIOCARBONYL-(<i>E</i>)-3-ALKENOIC ACIDS

Lithium dithioester enolates were found to react with β-alkenyl-β-propiolactones highly regio- and stereoselectively at the terminal vinyl carbon to give 6-(methylthio)thiocarbonyl-(E)-3-alkenoic acids, masked 1,7-dicarboxylic compounds.
