Synthesis and Fungicidal Activity of Novel 5-Arylpyrazole Derivatives
Abstract:
4-(2-Chlorophenyl)but-3-en-2-one was prepared Via the condensation of 2-chlorobenzaldehyde and acetone followed by cyclization with hydrazine monohydrate. Eighteen new 5-(2-hydroxyphenyl)-3-methyl(or ethyl)-4,5-dihydro-N-acylpyrazole derivatives were synthesized and characterized by elemental analysis, IR and 1H NMR. The experimental results show the inhibition rate of compound 3ae against P.oryzae was up to 60.2%, the inhibition rate of compound 3bf against S.Sclerotiorum was up to 56.7%. Conpounds 3aj and 3bj exhibited certain fungicidal activity against H.Oryzae, P.oryza, S.Sclerotiorum, with inhibition rate of up to 50%.
