Synthesis of Azo-Bridged Benzothiazole-Phenyl Ester Derivatives via Steglich Esterification
نویسنده
چکیده
We synthesized the five compounds of azo bridged ethoxybenzothiazole substituted phenyl ester derivatives by using Dicyclo Hexyl Carbodiimide (DCC) and a catalytic amount of Dimethyl amino pyridine (DMAP) as a nucleophile. All the compounds structures were confirmed by IR, NMR and mass spectrum. The synthesized compounds were screened for antioxidant property by DPPH radical scavenging method. (E)-4-[(6-ethoxy benzothiazol-2-yl) diazenyl] phenyl 2-methyl benzoate (B1) and (E)-4-[(6-ethoxy benzothiazol-2-yl) diazeny]) phenyl 4-fluoro benzoate (B5) showed comparable activities.

L-Tyrosine and L-Dopa are the precursors in the biological synthesis of amine neurotransmitters. On the other hand, phenylalanine as an aromatic amino acid (AAA) is a precursor in the synthesis of L-Tyrosine and L-Dopa. For some substrates such as amino acids, resolution by the formation of diastereomers offers an attractive alternative. Among different methods in this case, crystallization-ind...
