Main observation and conclusion

A general and practical protocol for the construction of diversified sulfur heterocycles has been described through organic electrosynthesis means. In undivided cell, dihydrothiophenes, thiazolines and 1,4-dithiines could be easily generated from various available β-ketothioamides under metal-free and external oxidant-free conditions. The transformation underwent smoothly under mild conditions and could be easily scaled-up. Moreover, different sulfur heterocycles were generated through varying solvent and 1,4-diazabicyclo[2.2.2]octane (DABCO) could enable the hydrogen atom transfer (HAT) process of this transformation.image
