Pyrazole compound, salt and uses thereof,

The invention discloses a pyrazole compound and a salt thereof, wherein the structural formula of the pyrazole compound is represented by a formula (I). According to the invention, the pyrazole compound has good prevention and control effect on various gr

Synthesis and bioactivity of pyrazole acyl thiourea derivatives

Sixteen novel pyrazole acyl thiourea derivatives 6 were synthesized from monomethylhydrazine (phenylhydrazine) and ethyl acetoacetate. The key 5-chloro-3- methyl-1-substituted-1H-pyrazole-4-carbonyl chloride intermediates 4 were first generated in four steps through cyclization, formylation, oxidation and acylation. Thess were then reacted with ammonium thiocyanate in the presence of PEG-400 to afford 5-chloro-3- methyl -1-substituted-1H-pyrazole-4-carbonyl isothiocyanates 5. Subsequent reaction with fluorinated aromatic amines resulted in the formation of the title compounds. The synthesized compound were unequivocally characterized by IR, 1H-NMR, 13C-NMR and elemental analysis and some of the synthesized compounds displayed good antifungal activities against Gibberella zeae, Fusarium oxysporum, Cytospora mandshurica and anti-TMV activity in preliminary antifungal activity tests.

METHOD FOR PRODUCING SUBSTITUTED PYRAZOLECARBOXYLIC ACID CHLORIDES

The present invention relates to a process for preparing substituted pyrazolyl chlorides by chlorinating aldehydes of the formula (II) under free-radical conditions.
