Description
(1) technical field
The present invention relates to a kind of pyrazole-containing bishydrazide compound, preparation method and its usage.
(2) background technology
Pyrazole compound is being played the part of important role in heterocyclic pesticide.Because that pyrazole compound shows is efficient, low toxicity and diversity structure, thereby has boundless research and development prospect.Before the present invention makes, there is the pesticide patent of relevant bishydrazide structure to occur abroad, tertiary butyl structure is arranged in the bishydrazide structure and do not have heterocycle structure.Domestic Lee rectifies name etc. pyrazole heterocycle and non-benzene ring structure is replaced two phenyl ring in two heterocycle structures, obtains a series ofly having-bishydrazide compound of CONH-structure, shows certain insecticidal activity.
(3) summary of the invention
The object of the invention is to provide a kind of pyrazole-containing bishydrazide compound of biologically active.
Described pyrazole-containing bishydrazide compound is suc as formula shown in (I):
Wherein X represents Cl, Br, R represent methylidene, nitro or chlorine atom.
A kind of preparation method of above-mentioned pyrazole-containing bishydrazide compound, comprise the steps: suc as formula the substituted-phenyl formyl chloride shown in the 1-methyl shown in (II)-3-ethyl-4-replacement-pyrazole-containing bishydrazide and the formula (III) under the acid-capture agent effect, carry out condensation reaction at 0～20 ℃ in organic solvent, aftertreatment gets product;
Wherein X and R definition is the same.
Based on the consideration of productive rate and cost, described condensation reaction time was good with 1～50 hour.
Described substituted-phenyl formyl chloride: 1-methyl-3-ethyl-4-replacement-pyrazole-containing bishydrazide: the molar ratio of acid-capture agent is preferably 1: 1.0～and 1.5: 1.0～2.0, described consumption of organic solvent is preferably 20～60 times of 1-methyl-3-ethyl-4-replacement-pyrazole-containing bishydrazide quality.
It is one of following that described acid-capture agent is preferably: triethylamine, pyridine, lutidine, Anhydrous potassium carbonate.
It is one of following that described organic solvent is preferably: tetrahydrofuran (THF), ethyl acetate, toluene, chlorobenzene, trichloromethane.
Described aftertreatment can be: use dilute hydrochloric acid washing reaction liquid to neutral, and layering, the organic phase drying is filtered, and concentrates, and column chromatography for separation gets described pyrazole-containing bishydrazide compound.
The preparation method of described pyrazole-containing bishydrazide compound recommends to be undertaken by following parameter:
The substituted-phenyl formyl chloride: 1-methyl-3-ethyl-4-replacement-pyrazole-containing bishydrazide: the molar ratio of acid-capture agent is 1: 1.0～1.1: 1.2～1.4, and consumption of organic solvent is 5～20 times of 1-methyl-3-ethyl-4-replacement-pyrazole-containing bishydrazide quality; Setting-up point is 0～20 ℃, and the reaction times is 10～20 hours.
Described 1-methyl-3-ethyl-4-replacement-pyrazole-containing bishydrazide can adopt following method to make:
1-methyl-3-ethyl-4-replacement-5-pyrazole carboxylic acid ethyl ester and excess hydrazine hydrate are carried out the stirring and refluxing reaction, and reaction finishes the back concentrating under reduced pressure, uses ethyl alcohol recrystallization, gets white, needle-shaped crystals and is described product.
Above-mentioned pyrazole-containing bishydrazide compound is as the application of insectofungicide.
Adopt toxic potato agar substratum (PDA) method that the fungicidal activity that the synthetic compound has carried out Pyricularia oryzae (Pyricularia oryzae), fusarium graminearum (Gibberella zeae), Phytophthora capsici germ (Phytophthora capsici) and botrytis cinerea pers (Botrytis cinerea) is measured, adopt potted plant stem and leaf of Wheat to preserve the spore method fungicidal activity that the synthetic compound has carried out wheat powdery mildew (Blumeria graminis) is measured.The result shows that described pyrazole-containing bishydrazide compound does not have the preventive effect effect substantially to fusarium graminearum, Phytophthora capsici germ, and rice blast fungus, botrytis cinerea pers, wheat powdery mildew are had different preventive effect effects.
Adopt the Potter spray method that the synthetic compound has been carried out the insecticidal activity assay of mythimna separata (Mythimna separata), adopt dipping plant method the synthetic compound to be carried out the insecticidal activity assay of green rice leafhopper (Nephotettix cincticeps).The result shows that described pyrazole-containing bishydrazide compound does not have insecticidal activity substantially to green rice leafhopper, and mythimna separata is had certain insecticidal activity, X=Cl especially, R=3-NO
2Formula (I) compound the inhibition activity of mythimna separata is reached 100%.
