Abstract
2,6-Dichlorobenzaldehydes reacted with hydroxylamine hydrochloride to form 2,6-dichlorobenzaldehydes oxime,followed by the chlorination with NCS,to form the corresponding chloro-2,6-dichlorobenzaldehyde oximes,which then underwent the 1,3-dipolar cycloaddition reaction with N-vinylpyrrolidone to generate3-(2,6-dichlorophenyl)-5-(1-pyrrolidone)-2,3-isoxazoline.The compound was characterized by 1 HNMR,13 CNMR and HRMS.Preliminary biological activity tests in vitroindicated that the compound had common fungicidal activities against the test funguses and displayed excellent fungicidal activity against Rhizoctonia solani in the test concentrations with the inhibitory rate of 95.8%.
