Synthesis of 1-aryl-3,4-dimethylenepyrrolidines by the thermal elimination of sulfur dioxide

This study demonstrates that thermal elimination of sulfur dioxide can effectively synthesize 1-aryl-3,4-dimethylenepyrrolidines in good yields, with accompanying products isolated and characterized.

Synthesis and configurational assignment of episulphoxides

Episulphoxides synthesized using our method have anti-configuration with respect to the substituent(s) and sulphinyl oxygen, making them unstable at room temperature and resulting in allylic thiolsulphinates.
