Synthesis and biological activity of acyl thiourea containing difluoromethyl pyrazole motif

Abstract

A series of new acyl thiourea derivatives containing difluoromethyl pyrazole moiety were designed and synthesized. Their structures were confirmed by 1H NMR, 31C NMR, MS and HRMS. The bioassay results showed that some of title compounds exhibited good in vivo fungicidal activity against Botrytis cinerea and Fusarium oxysporum and good antibacterial activity against Pseudomonas syringae pv. Lachrymans at 50 mg/L respectively.
