A convenient synthesis of tetrahydro-1Н-thieno-[3,2-с]pyrazole 4,4-dioxides
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-1 H -thieno[3,2- c ]pyrazole 4,4-dioxides, the structure of which was established by IR, 1 H, 13 C, 1 H...
