Glushkov, Vladimir A.; Babentsev, Dmitry N.; Dmitriev, Maksim V.; Stepanova, Kseniya A.; Kharintseva, Anastasiya Yu.; Simakhina, Anastasiya E. published the article 《The synthesis of 3-(het)aryl-6,7-dihydro-5H-[1,2,4]-triazolo[3,4-a][2]benzazepines》. Keywords: aryldihydrotriazolobenzazepine preparation; benzazepine hydrazide cyclization.They researched the compound: 2-Furoic hydrazide( cas:3326-71-4 ).Computed Properties of C5H6N2O2. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:3326-71-4) here.
4-Aryl-2-methylbutan-2-ols with methoxy or methylenedioxy substituents participate in the Graf-Ritter reaction with Me thiocyanate in the presence of an acid (H2SO4, MeSO3H) forming 1-methylsulfanyl-2-benzazepines in low yields (11-35%), which underwent cyclization with benzhydrazide or hetarenecarboxylic acid hydrazides upon reflux in o-dichlorobenzene into the corresponding 3-phenyl- and 3-hetaryl-6,7-dihydro-5H-1,2,4-triazolo[3,4-a][2]benzazepines I (R1 = R2 = OMe, R1+R2 = OCH2O; R3 = H, OMe; R4 = Ph, 2-furyl, 2-thienyl, 4-pyridyl) (45-74% yields).
This literature about this compound(3326-71-4)Computed Properties of C5H6N2O2has given us a lot of inspiration, and I hope that the research on this compound(2-Furoic hydrazide) can be further advanced. Maybe we can get more compounds in a similar way.
