  A series of 5-aryl-2-furancarbaldehyde 2,6-dialkylphenylhydrazones (Ia - Iv) and dimethylhydrazones (IIa - IIf) as well as related compound benzo[b]furan-2-carbaldehyde dimethylhydrazone (III) were prepared. Compounds Ia - Iv were synthesized by condensing 5-aryl-2-furancarbaldehydes with 2,6-dialkylphenylhydrazines, compounds IIa - IIf were obtained from the same starting compounds and N,N-dimethylhydrazine. The intermediate 5-aryl-2-furancarbaldehydes were prepared by reaction of aryldiazonium chlorides with 2-furancarbaldehyde. The structure of the compounds were proven by ¹H, ¹³C and ¹⁵N NMR spectra.

  The synthesis of ethyl 2-formyl-4-benzylfuro[3,2-b]pyrrole-5-carboxylate (I) is described. A series of furo[3,2-b]pyrrole-2-carbaldehyde 2,6-dialkylphenylhydrazones (IIa - IIg) and dimethylhydrazones (IIIa - IIId) were prepared. By reaction of title compounds with hydroxylammonium chloride in acetic anhydride in the presence of pyridine corresponding cyano-substituted compounds (IVa - IVd) were obtained. Alkaline hydrolysis of IVa - IVd gave Va - Vb and the reaction with sodium azide and ammonium chloride in dimethylformamide led to VIa - VId. the structure of the compounds have been proved by UV, IR, ¹H and ¹³C NMR spectra.
