Dehydroabietic acid chloride was prepared from dehydroabietic acid. Alkanoic diacid dihydrazides were synthesized using alkanoic diacids as starting materials via alkanoic diacid diethyl esters, followed by the reaction of alkanoic diacid dihydrazides with dehydroabietic acid chloride under phase transfer catalysis to afford N,N-didehydroabietacyl substituted alkanoic diacid dihydrazides. Five novel alkanoic diacid dialkyl-didehydroabietyl-bis-oxadiazoles were synthesized by the cyclization of N,N-didehy- droabietacyl substituted alkanoic diacid dihydrazides. The novel compounds were characterized by means of elemental analysis, 1H NMR, 13C NMR, IR and MS techniques. The preliminary herbicidal activity test showed that compounds 6b6e displayed good growth inhibition against root of rape at the concentration of 100 μg/mL, which had the inhi-bition rates >80%.

Key words: dehydroabietic acid, 1,3,4-oxadiazole, synthesis, herbicidal activity
