Synthesis of new triazole-fused bicyclic heterocycles involving benzofuran from 4-amino-1,2,4-triazole-3-thiol

Tóm tắt

In the further research and synthesis of hybrid molecules which exhibit highly biological activities, the synthesis of triazole-fused bicyclic heterocycles bearing the benzofuran has been undertaken. A facile, convenient and good yielding synthesis of novel benzofuran-bearing 1,2,4-trazole derivatives were described. Herein, two derivatives of [1,2,4]triazolo[3,4-b][1,3,4]thiadiazole were synthesized from salicylaldehyde in four steps in moderate to good yields. Structures of all the targeted synthesized compounds were elucidated by spectral methods of analysis.
