Oxidation-reduction and heterocyclization of the reactions of alkanedithiols with pi-deficient compounds

摘要

The reaction of 1,2-ethanedithiol and 1,3-propanedithiol with pi-deficient compounds afforded various oxidation-reduction and cyclized products under mild conditions. Heterocycles containing one sulfur atom (e.g. analogues of seriniquinone) were also obtained. The structures of the products were elucidated by NMR, IR, mass spectral data, and elemental analyses. The mechanisms were also discussed.
