Fourteen novel pyrazole oxime ether derivatives containing a 2-chloro-5-methyl pyridyl ring were synthesized by the reaction of 1-phenyl-3-methyl-5-aryloxy-1H-pyrazole-4-carbaldehyde oximes with 2-chloro-5-chloromethyl pyridine. The structures of all new compounds were confirmed by 1H NMR, 13C NMR spectra and elemental analysis. Preliminary bioassay results indicated that some compounds exhibited certain fungicidal and plant growth regulatory activities.

Key words: substituted pyridine, pyrazole oxime, synthesis, bioactivities
