3-Aryl-6а-methyl-6-nitro-1-carbamoylhexahydrothieno[2,3-d]pyrazole-4,4-dioxides, novel original bicyclic species consisting of fused pyrazolidine and sulfolane rings, and 1,4-adducts were obtained by reacting 2-benzylidene-3-methyl-4-nitro-3-thiolene-1,1-dioxide and its derivatives with semicarbazide.Keywordssulfolanepyrazolidinebicyclic compoundsnitrosulfodienessemicarbazidenucleophilic additionheterocyclization
