In the search for novel sterol demethylase inhibitors (DMIs), a series of 1,2,4-triazole derivatives containing oxime ether and cyclopropyl moieties were designed using the bioactive substructure combination assisted by virtual molecular docking. The above-mentioned target compounds were characterized using the1H NMR,13C NMR,19F NMR, and HR-MS spectra. The antifungal evaluation againstRhizoctonia solani(Rs),Fusarium graminearum(Fg), andBotrytis cinerea(Bc) indicated that most of the target compounds exhibited remarkable inhibitory activities against the above-mentioned tested fungi. Significantly, the compound5kexhibited outstanding anti-Fgactivity with an EC50value of 1.22 μg mL?1in vitro, and a protective effect of 59.45%in vivoat 200 μg mL?1. Further investigation revealed that compound5kevidently inhibitedFgspore germination and caused some wrinkles and dents on the surface of mycelia. Molecular docking showed that compound5kbound with the target proteinFgCYP51viacoordination, hydrogen bonding and stacking interactions that were similar, but slightly different from the interactions of tebuconazole withFgCYP51. These research results suggested that the target compounds are valuable for the further structural optimization of novel triazole fungicides.

A novel process involving base-catalyzed intramolecular defluorination/O-arylation of readily available α-fluoro-β-one-sulfones was realized and provided a series of 3-fluoro-1,4-oxathiine 4,4-dioxide derivatives in good to excellent yields. Unlike traditional defluorination reactions with stoichiometric base as the deacid reagent, this process is triggered by a catalytic amount of base (TMG: tetramethylguanidine) and molecular sieves serve as both an adsorbent to remove HF acid and an activator to assist C-F bond cleavage.
