Efficient synthesis and fungicidal activities of strobilurin analogues containing benzofuro [3,2-d]-1,2,4-triazolo[1,5-a]pyrimidinone side chains

Abstract

AbstractAn efficient method for the preparation of strobilurin analogues containing benzofuro[3,2-d]-1,2,4-triazolo[1,5-a]pyrimidinone side chains were reported. This method is based on the reaction of functionalized iminophosphoranes with carbon disulfide via aza-Wittig reaction. The preliminary investigations on the biological activities show that the majority of compounds synthesized have moderate fungicidal activities against six kinds of fungi at a concentration of 50 mg/L.
