摘要：
The reaction of oxidation of 3-aryl-6a-methyl-6-nitrohexahydrothieno[2,3-d]pyrazole 4,4-dioxides by bromine was used to synthesize their derivatives 3-aryl-6a-methyl-6-nitro-3a,5,6,6a-tetrahydro-1H-thieno[3,2-c]pyrazole 4,4-dioxides, the structure of which was established by IR, 1H, 13C, 1H–13C HMQC, 1H–13C HMBC spectroscopy and X-ray structural analysis.
