The synthesis of the novel m-substituted S-methyl thiocinnamates 1 ± 4 is described. Cathodic reductions of S-esters 1 ± 3, carried out at constant potentials corresponding to their first voltammetric E pc , in a polar aprotic solvent, led exclusively to the racemic all-trans-configured 2,3-diaryl-5-oxocyclopentane-1-carbothioates, as shown by assignments of 1 H-NMR coupling constants.Introduction. ± The electrohydrodimerization (EHD) of alkenes, activated towards cathodic reduction by electron-withdrawing gr…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
