Synthesis method of pyrazolopyrimidine compounds

The invention relates to a synthesis method of pyrazolopyrimidine compounds. On the basis of the prior art, sodium iodide or potassium iodide is introduced to a hydrazinolysis reaction, the yield andthe purity are increased through the hydrazinolysis step, and accordingly, the total yield is increased. The method has the advantages of mild reaction conditions, high reaction yield and purity, lowproduction cost and the like, and is suitable for production on an industrialization scale.

A pyrazolo pyrimidine compound and use thereof

The invention discloses a compound shown in general formula I and an application thereof as a plant disease-resistant activator, wherein R1 is independently selected from hydrogen, C1-C6 alkyl, C1-C6 halogenated alkyl, C3-C6 naphthenic base, halogen, nitro and hydroxyl; R2 is independently selected from C1-C6 alkyl, C1-C6 halogenated alkyl, hydroxyl, C1-C6 alkoxy, C1-C6 halogenated alkoxy, substituted or unsubstituted C6-C14 aryl, halogen, nitro, amino, C1-C6 alkoxy, carboxyl, C1-C3 alcoxyl formyl and pentabasic or hexahydric nitrogen and heterocyclic ring of oxygen or sulfur-containing; n is selected from 0-5. The compound is used for inhibiting the pathogens through inducing the plants to generate disease resistance, rather than directly killing or inhibiting the pathogens; the compound has the advantages of systematicness, long-lasting effect, broad spectrum and safety, so that the dosage of highly toxic pesticide can be reduced, and environment friendliness, great industrial/commercial prospect and market value are achieved.
