- All new compounds were adequately characterized by spectroscopic methods and by exact mass measurement and/or elemental analysis. Most products exist partially in the corresponding enol form
- The reaction was carried out using 1.5 eq of S,S'-dimethyl dithiocarbonate
- This compound exists completely in the enol form. The structure was confirmed by oxidation with DDQ in refluxing benzene to the corresponding 1,2-dehydro derivative
