Synthesis and Electrohydrodimerization ofmeta-Substituted Thiocinnamic AcidS-Esters
摘要:
The synthesis of the novel m-substituted S-methyl thiocinnamates 1-4 is described. Cathodic reductions of S-esters 1-3, carried cut 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 H-1-NMR coupling constants.
