Hys, Vasyl Y. published the artcileSynthetic Approach to Fused Azasultams with 1,2,4-Thiadiazepine Framework, Formula: C9H8N2O2, the main research area is fused azasultam thiadiazepine preparation; azole pyrrole carboxylate sulfonamide heterocyclization.
Synthetic approach to fused azasultams with 1,2,4-thiadiazepine framework via base promoted protocols has been developed. 1H-Azole-2-carboxylates and N-(chloromethyl)-N-methylmethanesulfonamide were used as ambiphilic building blocks in the one-pot and two-step reaction sequences. Chem. behavior of the obtained azasultams in reactions with amines, hydrazine, DMFDMA, and NaBH4 was investigated. An enamino ketone derived from an azasultam was exploited in the synthesis of new pyrazole and pyrimidine heterocycles.
Synthesis published new progress about Condensation reaction (sulfa-Dieckmann). 5805-53-8 belongs to class imidazoles-derivatives, name is Methyl 1H-benzo[d]imidazole-2-carboxylate, and the molecular formula is C9H8N2O2, Formula: C9H8N2O2.
