A new Schiff base, 4-{[(4-methylphenyl)imino]methyl}-3-hydroxyphenyl 4-(hexadecanoyloxy)benzoate was synthesized and its IR, ¹H NMR, ¹³C NMR and MS spectroscopic data are presented.

2-tert-Butyl-5,6,7,8,9,10-hexahydrocyclohepta[b]indole was synthesized by reaction of cycloheptanone and (4-tert-butylphenyl)hydrazine hydrochloride in the presence of sodium acetate and sulfuric acid in glacial acetic acid via Fischer indole synthesis.

The title compound, anthracen-9-ylmethylene-(3,4-dimethylisoxazol-5-yl)amine (3), was synthesized in high yield by reaction of anthracene-9-carbaldehyde and 5-amino-3,4-dimethyl­isoxazole in ethanol. The structure of this new compound was confirmed b...

A new Schiff base ester, 4-({[4-(methylthio)phenyl]methylene}amino)phenyl dodecanoate was synthesized and its IR, ¹H NMR, ¹³C NMR and EI-MS spectroscopic data are presented.

The title compound, 3-chloro-N'-(2-hydroxy-4-pentadecylbenzylidene)­benzo[b]thiophene-2-carbohydrazide has been synthesized by reaction of 2-hydroxy-4-pentadecylbenzaldehyde with 3-chloro-1-benzo[b]thiophene-2-carboxylic acid hydrazide in the presenc...

A novel 1,2,4-triazin-6-one derivative (2) was synthesized by the reaction of the oxazolone derivative 1 with 4-nitrobenzoic acid hydrazide in the presence of sodium acetate and glacial acetic acid. The title compound 2 was characterized on basis of...

A new Schiff base ester, 4-{[(4-iodophenyl)imino]methyl}phenyl octadecanoate was synthesized and its IR, ¹H NMR, ¹³C NMR and EI-MS spectroscopic data are presented.

A novel benzimidazole derivative (2) was synthesized by hydrolyzing 4-[(5-chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)methylene]-2-phenyloxazol-5(4H)-one (1), the azlactone precursor in an acidic medium and treating the product with o-phenylenediamine (...

Herein, we synthesized 2,3-diaminophenazine (DAP) from o-phenylenediamine (OP) using fungal laccase as a biocatalyst. The conversion ratio of OP monomer was 85% and the yield of the final purified product, DAP, was 63%. The structure of the main prod...
