Synthesis and characterization of new 1-naphthyl-3, 5-disubstituted triazoles

الملخص EN

Novel oxazolin-5-one derivatives 1a, b were prepared and used as starting materials for the synthesis of triazolobenzimidazole derivatives 2a, b, N-4`-aminophenyl-1-naphthyl 5-substituted 1, 2, 4-triazol-3- carboxyamide 3a, b.

The reaction of compounds 1a, b with resorcinol, 1-and / or 2-naphthols gave triazolo -3-carboxylate derivatives 4a-f.

Compounds 4a, b, d, e were rearranged according to the Fries rearrangement reaction to give 5a-d.

Fries rearrangement products 8a, b have been obtained also by refluxing compounds 3a, b with anhydrous zinc chloride and acetic acid.

Reaction of Fries rearrangement products 5a-d and / or 8a, b with malononitrile in acetic acid, dry benzene and ammonium acetate gave compounds 6a, b, 7a, b And / or 9a, b respectively.
