of synthetic and biological importance. Hydrazine hydrate reacted with furanones as nucleophiles and gave the corresponding acid hydrazides 4. The latter products were used as starting materials for the synthesis of 1,3,4‐oxadiazoles 6, 9, and the 1,2,4‐triazoles 8. Evaluation of the antiviral activity of selected compounds obtained was performed using two viruses: HAV and HSV‐1. Some of the tested compounds
