Synthesis, Characterization and DFT Molecular Modeling of New Antibacterial Docked Dicarbohydrazones

“…9,10‐Dihydro‐9,10‐ethanoanthracene‐11,12‐dicarbohydrazide (2) has been prepared in the light of the previously reported literature from the reaction of dibenzobarallene (1) with two moles of hydrazine hydrate (Scheme ). The reaction of dicarbohydrazide derivative 2 with various types aromatic and heterocyclic aldehydes (namely; 4‐anisaldehyde, 2,4‐dihydroxybenzaldehyde, 2‐hydroxy‐6‐methoxybenzaldehyde, furfural and 2‐formylpyrrole) was achieved via heating in ethanol to yield the conforming dicarbohydrazones 3 a‐e .…”

“…Treatment of 185 with hydrazine hydrate yielded diacid hydrazide 186. 83 Dihydrazide 186 was reacted with acetyl acetone to afford pyrazole derivative 187. Compound 186 was also reacted with aromatic aldehydes to afford diarylidene hydrazonyl derivatives 188.…”

“…Compound 186 was also reacted with aromatic aldehydes to afford diarylidene hydrazonyl derivatives 188. 83 Moreover, the reaction of dihydrazide derivatives 186 with isothiocyanate derivatives furnished corresponding dithiosemicarbazides 189. 83 The latter adduct, 189, cyclized with alcoholic KOH followed by acidification with dilute HCl to yield ditriazole derivative 190.…”
