Abstract

The present invention relates to a 3-substituted-5-methyl-4-methylene-7-methylthio-3, 4-dihydro-pyrido [4, 3-d]pyrimidine-8-nitrile compound with bactericidal and herbicidal activity. The general formula of the compound is shown as the specification, wherein R represents alkyl or substituted alkyl, alkenyl, alkynyl, heterocyclic substituted alkyl, fused heterocycle substituted alkyl, hydroxy alkyl, phenyl alkyl or substituted phenyl alkyl, substituted or non-substituted phenoxy-acetylamino or phenoxy-propionamido. The compound has obvious inhibiting effects on strains, such as cotton wilt fungi, rhizoctonia solani, botrytis cinerea pers, gibberella saubinetii, apple ring rot, cotton anthracnose, sclerotinia rot of colza, beet cercospora leaf spot, Bipolaris maydis, etc. Thus, the compound can be used as a bactericide. Simultaneously, the compound has obvious inhibiting effects on the growth of monocotyledon or dicotyledon, and is capable of being used as an effective constituent of herbicides.

Description

One class has also [4,3-d] pyrimidine and preparation of polysubstituted pyridine of bactericidal and herbicidal activity
Technical field
The present invention relates to have the 3-substituted alkyl-5-methyl-4-methylene radical-7-methylthio group-3 of fungicidal activity and weeding activity, the preparation of 4-dihydro-pyrido [4,3-d] pyrimidine-8-nitrile and intermediate thereof, and it is as the biological activity of sterilant, weedicide.
Background technology
Pyrido [4,3-d] pyrimidines be study both at home and abroad in recent years very popular heterocycle compound.This compounds not only has medicinal activity but also have pesticide activity, physiology and pharmacologically active widely particularly aspect medical research, have been shown, can be used for treating various types of tumours, cancer, from the blood disease, acquired immune deficiency syndrome (AIDS) and many nervous system diseases also can be used for health medical treatment aspects such as pain relieving, anti-inflammatory, antianaphylaxis in addition.
The pyrido [4 to having pesticide activity of early stage report, 3-d] research of pyrimidines all concentrates on aspects such as sterilant, Insecticides (tech) ﹠ Herbicides (tech), but relevant pyrido [4 over past ten years, 3-d] bioactivity research of pyrimidine skeleton compounds mainly concentrates on the pharmacological activity aspect, and to the research report of its pesticide activity seldom.For the pesticide activity to this type of novel cpd is further studied, we have studied the synthetic method of such novel cpd, the pyridine synthesis of having invented a kind of novelty of not seeing bibliographical information also [4,3-d] pyrimidines, and its biological activity has been carried out test found with it and to have good bioactive compound.
Summary of the invention
The objective of the invention is to explore and have new texture and have sterilization and the polysubstituted pyridine of weeding activity also [4,3-d] pyrimidine derivatives, provide a class to have fungicidal activity, and have the 3-substituting group-5-methyl-4-methylene radical-7-methylthio group-3 of weeding activity concurrently, 4-dihydro-pyrido [4,3-d] pyrimidine-8-nitrile compounds and synthetic method thereof.
General structure of the present invention such as I:
Figure C20051001957600041
In the formula, R represents: C 1-C 6Alkyl or halogen-substituted alkyl, thiazolinyl, alkynyl; Heterocyclic radical is the heterocyclic substituted C of pyridine, thiophene or furans 1-C 4Alkyl; Heterocyclic radical is that the fused heterocycle of pyrido [4,3-d] pyrimidine replaces C 1-C 6Alkyl; Hydroxyl C 1-C 4Alkyl; Phenyl C 1-C 4Alkyl or substituted-phenyl C 1-C 4Alkyl; Benzene oxygen kharophen or substituted benzene oxygen kharophen, benzene oxygen propionamido or substituted benzene oxygen propionamido; Substituting group on the related phenyl ring is mainly: halogen, C 1-C 6Alkyl or alkoxyl group, substituting group is in phenyl ring arbitrary locational single replace or polysubstituted, the substituting group on phenyl ring is identical or inequality.
The structure of compound proposed by the invention does not have other patents or bibliographical information.
The present invention finds to have the compound of said structure general formula I to cotton wilt fusarium, magnaporthe grisea, botrytis cinerea, gibberella saubinetii, ring rot of apple, cotton anthracnose, sclerotinia rot of colza, multiple bacterial classifications such as beet cercospora leaf spot and corn stigma bacterium have significant inhibitory effect, can be used as the effective constituent of sterilant.Growth to unifacial leaf or dicotyledons simultaneously has significant inhibitory effect, the effective constituent of useful as herbicides.
The polysubstituted pyridine of representing with general formula I is the preparation method of [4,3-d] pyrimidine derivatives also, is after making represented compound of general formula I I and triethyl orthoformate reaction generate intermediate III, again with C 1-C 6Alkylamine or halogen-substituted alkyl amine, C 1-C 6Enamine or halogen substituted enamine, C 1-C 6Ynamine or halogen replace ynamine, C 1-C 4Hydroxyalkyl amine, phenyl C 1-C 4Alkylamine or substituted pheynylalkylamine, benzene oxygen acethydrazide or substituted benzene oxygen acethydrazide, benzene oxygen propionyl hydrazine or substituted benzene oxygen propionyl hydrazine and heterocyclic substituted C 1-C 4Alkylamine is closed ring in room temperature or heating condition, can obtain better productive rate.
The synthetic route of the compound of representing with general formula I is as follows:
Figure C20051001957600051
RNH 2The definition of R is identical with the definition of R among the general structure I in the formula.
II in the above-mentioned reaction formula and triethyl orthoformate mol ratio are 1: 1-3, adopt organic solvent chloroform, methylene dichloride, tetracol phenixin, acetone, ethyl acetate or ether at 0 ℃-80 ℃ or directly to adopt triethyl orthoformate be that solvent reacted 10-25 hour between 100 ℃-150 ℃, obtain intermediate III, intermediate III again with RNH 2With mol ratio is 1: 1-3, organic solvent are ethanol, methyl alcohol, acetonitrile, ethyl acetate, dioxane or dimethyl formamide (DMF), 20 ℃-120 ℃ reactions 2-12 hour, can obtain yield preferably.

The fungicidal activity test
Test materials:
For trying bacterial classification: cotton wilt fusarium (Fusarium oxysporum.), rice banded sclerotial blight bacterium (Rhizoctonia solani), botrytis cinerea (Botrytis cinereapers.), gibberella saubinetii (Gibberella zeae.), apple wheel line bacterium (Botryosphaeriaberengerinan) and corn stigma bacterium (Bipilaris maydis)
Testing method:
Watch-glass isolated activity assay method:
With the 200g peeling potatoes, boil in 700mL distilled water the chopping back, cold filtration, and filtrate is mixed with glucose, agar, adds water to 900mL again, is heated to boiling, promptly gets substratum after the cooling.Substratum, distilled water and culture dish are sterilized together.With electronic balance weighing 3mg testing sample, add dimethyl formamide (DMF) dissolving, drip 1 tween-80, adding distil water is mixed with concentration 1000 μ g/g solution.
Substratum high temperature decompression sterilization 15 minutes, after the sterilization, measure the 10mL culture medium after sterilization while hot with the scale test tube, with itself and 1mL, the 10mL sample mixing that 1000 μ g/g solution obtain with 10 times of distilled water dilutings, can make the sample that concentration is 50 μ g/g, build the culture dish loam cake, the horizontal positioned cooling.
With diameter is that the punch tool of 5mm is got the blank agar block, chooses in the culture dish with light gage wire, and mycelia faces down, and each culture dish is placed 2-3 kind bacterium.Getting preceding punch tool of bacterium and light gage wire must sterilize with the spirit lamp calcination.Use aforesaid method, do not add testing sample, each bacterial classification is done the primary blank contrast.Place 48-72 hour " Invest, Then Investigate " in the sterile constant-temperature case then.Measure the diameter of bacterial plaque, according to the blank photograph, suppress the expression drug effect with diameter: inhibiting rate %=[(CK-handles)/CK] * 100%
