Modified synthesis and structural features of 2-benzylidene-4-nitro-2,5-dihydrothiophene 1,1-dioxides
A modified procedure for achieving condensation reactions between 3-methyl-4-nitro-2,5-dihydrothiophene 1,1-dioxide and aromatic aldehydes was used to synthesize a broad range of previously unknown 2-benzylidene-4-nitro-2,5-dihydrothiophene 1,1-dioxides – promising substrates for the assembly of fus...

Summary: | A modified procedure for achieving condensation reactions between 3-methyl-4-nitro-2,5-dihydrothiophene 1,1-dioxide and aromatic aldehydes was used to synthesize a broad range of previously unknown 2-benzylidene-4-nitro-2,5-dihydrothiophene 1,1-dioxides – promising substrates for the assembly of fused polycyclic nitrosulfolane derivatives. The structural features of the obtained nitrosulfodienes were established on the basis of IR spectra,
