Synthesis of novel diaryloxocyclopentanethiocarboxylates by electrochemical reduction of cinnamic acid thioesters
Abstract
The cathodic cyclic electrohydrodimerisation of a series of para-substituted (E
)-methyl thiocinnamates in a polar aprotic solvent is presented. Only the all-trans (±)-3,4-diaryl-1-oxocyclopentane-2-thiocarboxylates are formed, as shown by assignments of 1H NMR coupling constants.
