Description

The present invention relates to new triazolopyrimidines, a method for their production, and their use for combating undesired micro-organisms. In addition, the present invention relates to new intermediate products and methods for their production.


It is already known that specific triazolopyrimidines have fungicidal properties (cf. DE-A 101 21 162 and EP-A 0 613 900). The efficiency of these substances is good but in some cases, leaves something to be desired when low quantities are used.

  • R1 represents optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted cycloalkyl, or optionally substituted heterocyclyl,
  • R2 represents hydrogen or alkyl, or
  • R1 and R2 together with the nitrogen atom to which they are bound, represent a optionally substituted heterocyclic ring,
  • R3 represents halogen, optionally substituted alkyl, or optionally substituted cycloalkyl,
  • R4 represents optionally substituted heterocyclyl,
  • X represents halogen,


    have now been found.


Furthermore, it has been found that triazolopyrimidines of the formula (I) may be produced by reacting

  • (a) dihalogentriazolopyrimidines of the formula
    embedded image

    in which
  • R3, R4 and X have the meanings specified above and
  • Y1 represents halogen,


    with amines of the formula
    embedded image

    in which
  • R1 and R2 have the meanings specified above,


    optionally in the presence of a diluent, optionally in the presence of an acid acceptor, and optionally in the presence of a catalyst.


Finally, it has been found that triazolopyrimidines of the formula (I) are very well suitable for combating undesired micro-organisms. Above all, they display a strong fungicidal activity and may be used both in plant protection and also in material protection.


Surprisingly, the triazolopyrimidines of the formula (I) have a significantly better microbicidal activity than the most constitutionally similar previously known materials of identical direction of activity.


The compounds of the formula (I) according to the present invention may optionally be provided as mixtures of different possible isomeric forms, particularly stereoisomers, such as E and Z, threo and erythro, and also optical isomers, such as R and S isomers or atropisomers, optionally even tautomers.


Both the pure stereoisomers and also any arbitrary mixtures of these isomers are the object of the present invention, even if generally only the compounds of the formula (I) are discussed here.


Depending on the type of the substituents defined above, the compounds of the formula (I) have acid or basic properties and may form salts. If the compounds of the formula (I) carry hydroxy, carboxy, or other groups which induce acid properties, these compounds may be reacted with bases to produce salts. Suitable bases are, for example, hydroxides, carbonates, hydrogen carbonates of the alkaline and alkaline earth metals, particularly those of sodium, potassium, magnesium, and calcium, as well as ammonia, primary, secondary, and tertiary amines having (C1-C4) alkyl residues as well as mono-, di-, and trialkanolamines of (C1-C4) alkanols. If the compounds of the formula (I) have amino, alkylamino, or other groups inducing basic properties, these compounds may be reacted with acids to produce salts. Suitable acids are, for example, mineral acids, like hydrochloric acid, sulphuric acid, and phosphoric acid, organic acids such as acetic acid or oxalic acid, and acid salts, such as NaHSO4 and KHSO4. The salts which may thus be obtained also have fungicidal and microbicidal properties.


The object of the present invention is also the salt-like derivatives produced from compounds of the formula (I) through reaction with the basic and/or acidic compounds as well as the N oxides producible according to typical oxygenation methods.


In the present case, heterocyclyl represents saturated or unsaturated, aromatic or non-aromatic cyclic compounds having 3 to 8 ring members, in which at least one ring member represents a heteroatom, i.e., an atom different from carbon. If the ring contains multiple heteroatoms, these may be identical or different. Heteroatoms are preferably oxygen, nitrogen, or sulphur. If the ring contains multiple oxygen atoms, these are not directly neighboring. The cyclic compounds optionally jointly form a polycyclic ring system with further carbocyclic or heterocyclic, fused or bridged rings. Monocyclic or bicyclic ring systems, particularly monocyclic or bicyclic aromatic ring systems are preferred.


The triazolopyrimidines according to the present invention are generally defined by the formula (I). Those materials of the formula (I), in which

  • R3 represents fluorine, chlorine, bromine, iodine, alkyl having 1 to 4 carbon atoms, halogenalkyl having 1 to 4 carbon atoms and 1 bis 9 halogen atoms or cycloalkyl having 3 to 6 carbon atoms,

The active ingredients according to the present invention also have a very good strengthening effect in plants. They are therefore suitable for mobilizing plant defences against infection by undesired micro-organisms.


Plant-strengthening (resistance-inducing) materials are to be understood in the present context as those substances which are capable of stimulating the defence system of plants in such a way that, upon subsequent inoculation with undesired micro-organisms, the treated plants unfold extensive resistance to these micro-organisms.


In the present case, undesired micro-organisms are to be understood as phytopathogenic fungi, bacteria, and viruses. The materials according to the present invention may thus be used for protecting plants against infection by the pathogens cited within a certain period of time after treatment. The period of time within which this protection is provided generally extends from 1 to 10 days, preferably 1 to 7 days after the treatment of the plants with the active ingredients.


The good phytotolerance of the active ingredients in the concentrations necessary for combating plant diseases allows treatment of aboveground plant parts, of plants and seeds, and of the soil.


In this case, the active ingredients according to the present invention may be used especially successfully for combating grain diseases, such as Erysiphe species, and of diseases in wine, fruit, and vegetable farming, such as Botrytis, Venturia, Sphaerotheca and Podosphaera species.


The active ingredients according to the present invention are also suitable for increasing the harvest yield. They also have low toxicity and good phytotolerance.


The active ingredients according to the present invention may optionally also be used in specific concentrations and applied quantities as herbicides, to influence plant growth, and to combat animal pests. They may also be used as intermediate and precursor products for synthesizing further active ingredients if necessary.


According to the present invention, all plants and plant parts may be treated. Plants are understood in this case as all plants and plant populations, such as desired and undesired wild plants or cultured plants (including naturally occurring cultured plants). Cultured plants may be plants which are obtained through conventional cultivation and optimization methods or through methods of biotechnology and genetic engineering or combinations of these methods, including transgenic plants and including plant species which may or may not be protected by species protection rights. Plant parts are to be understood as all aboveground and below ground parts and organs of the plants, such as sprouts, leaves, flowers, and roots, for example, leaves, needles, stakes, stems, flowers, fruits, and seeds, as well as roots, bulbs, and rhizomes being listed. The plant parts also include hereditary material as well as vegetative and generative propagation material, such as slips, bulbs, rhizomes, cuttings, and seeds.


The treatment of the plants and plant parts according to the present invention using the active ingredients is performed directly or through the effect on their environment, living space, or storage space according to the typical treatment methods, e.g., through dipping, spraying, vaporizing, misting, scattering, painting, and for propagation material, particularly for seeds, also through single-layer or multilayered enveloping.


In material protection, the materials according to the present invention may be used for protecting technical materials against infection and destruction by undesired micro-organisms.


Technical materials are to be understood in the present context as inanimate materials which have been prepared for use in technology. For example, technical materials which may be protected by active ingredients according to the present invention from microbial change or destruction are adhesives, glues, paper and cardboard, textiles, leather, wood, paints and plastic articles, coolants, and other materials which may be infected or destroyed by micro-organisms. Parts of production facilities, such as coolant water loops, which may be impaired by reproduction of microorganisms, are also cited in the scope of the materials to be protected. Preferably, adhesives, glues, paper and cardboard, leather, wood, paints, coolants, and thermal transfer fluids are cited as technical materials in the scope of the present invention, especially preferably wood.


For example, bacteria, fungi, yeasts, algae, and slime organisms are cited as micro-organisms which may cause degradation or change of the technical materials. Preferably, the active ingredients according to the present invention act against fungi, particularly mold fungi, wood-staining and wood-destroying fungi (Basidiomycetes), and against slime organisms and algae.


Micro-organisms of the following species are cited as examples:



Alternaria, such as Alternaria tenuis,



Aspergillus, such as Aspergillus niger,



Chaetomium, such as Chaetomium globosum,



Coniophora, such as Coniophora puetana,



Lentinus, such as Lentinus tigrinus,



Penicillium, such as Penicillium glaucum,



Polyporus, such as Polyporus versicolor,



Aureobasidium, such as Aureobasidium pullulans,



Sclerophoma, such as Sclerophoma pityophila,



Trichoderma, such as Trichoderma viride,



Escherichia, such as Escherichia coli,



Pseudomonas, such as Pseudomonas aeruginosa,



Staphylococcus, such as Staphylococcus aureus.


As a function of their particular physical and/or chemical properties, the active ingredients may be converted into the typical formulations, such as solvents, emulsions, suspensions, powders, foams, pastes, granules, aerosols, extremely fine encapsulations in polymer materials, and into envelope compounds for seeds, as well as ULV cold and hot mist formulations.


These formulations are produced in ways known per se, e.g., by mixing the active ingredients with extenders, i.e., liquid solvents, liquefied gases under pressure, and/or solid carrier materials, optionally using surfactants, i.e., and also emulsifiers and/or dispersing agents and/or foam-producing agents. If water is used as an extender, organic solvents may also be used as an auxiliary solvents, for example. The following solvents essentially come into consideration as the liquid solvent: aromatics, such as xylene, toluene or alkylnaphthaline, chlorinated aromatics or chlorinated aliphatic hydrocarbons, such as chlorobenzene, chloroethylene or methylene chloride, aliphatic hydrocarbons, such as cyclohexane, or paraffins, such as petroleum fractions, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methylethylketone, methylisobutylketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethylsulphoxide, as well as water. Liquefied gaseous extenders or carriers are those liquids which are gaseous at normal temperature and under normal pressure, such as aerosol propellant gases, such as halogenated hydrocarbons as well as butane, propane, nitrogen and carbon dioxide. The following materials come into consideration as solid carriers: for example, natural rock flours, such as kaolin, aluminum oxide, talcum, chalk, quartz, attapulgite, montmorillonite or diatomaceous earths and synthetic rock flours, such as highly dispersed silicic acid, aluminum oxide and silicates. The following materials come into consideration as solid carriers for granules: for example, broken and fractionated natural stones such as calcite, pumice, marble, sepiolite, dolomite, as well as synthetic granulates made of inorganic and organic flours and granulates made of organic material like sawdust, coconut shells, maize cobs, and tobacco stalks. The following materials come into consideration as emulsifiers and/or foam-producing agents: for example, non-ionogenic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, e.g., alkylaryl polyglycolethers, alkyl sulphonates, alkyl sulphates, aryl sulphonates and protein hydrolysates. The following materials come into consideration as dispersing agents: e.g., lignin sulphite waste liquors and methyl cellulose.


Adhesives such as carboxymethylcellulose, natural and synthetic powdered, grainy, or latex polymers may be used in the formulations, such as gum arabic, polyvinylalcohol, polyvinylacetate, as well as natural phospholipids, such as kephalins and lecithins, and synthetic phospholipids. Further additives may be mineral and vegetable oils.


Coloring agents such as inorganic pigments, e.g., iron oxide, titanium oxide, ferrocyanide blue, and organic coloring agents such as alizarin, azo and metal phthalocyanine coloring agents and trace nutrients, such as salts of iron, manganese, boron, copper, cobalt, molybdenum, and zinc may be used.


The formulations generally contain between 0.1 and 95 percent by weight active ingredient, preferably between 0.5 and 90%.


The active ingredients according to the present invention may also be used per se or in their formulations with known fungicides, bactericides, acaricides, nematicides or insecticides, in order to thus broaden the activity spectrum or avoid the development of resistance, for example. In many cases, synergistic effects are achieved in this case, i.e., the effectiveness of the mixture is greater than the effectiveness of the individual components.

as well as preparations which contain insecticidally active plant extracts, nematodes, fungi, or viruses.


A mixture with other known active ingredients, such as herbicides, or with fertilizers and growth regulators, safeners, and/or semiochemicals is also possible.


In addition, the compounds of the formula (I) according to the present invention also have very good antimycotic effect. They have a very broad antimycotic activity spectrum, particularly against dermatophytes and sprout fungi, mold and diphasic fungi (e.g., against Candida species such as Candida albicans, Candida glabrata) as well as Epidermophyton floccosum, Aspergillus species such as Aspergillus niger and Aspergillus fumigatus, Trichophyton species such as Trichophyton mentagrophytes, Microsporon species such as Microsporon canis und audouinii. The list of these fungi does not represent a restriction of the mycotic spectrum which may be contained, but rather only has explanatory character.


Furthermore, the compounds of the formula (I) according to the present invention are suitable for suppressing the growth of tumour cells in humans and mammals. This is based on an interaction of the compounds according to the present invention with tubulin and microtubules and through encouragement of microtubule polymerization.


For this purpose, an effective quantity of one or more compounds of the formula (I) or pharmaceutically compatible salts thereof may be administered.


The active ingredients may be applied as such, in the form of their formulations or the application forms prepared therefrom, such as ready-to-use solutions, suspensions, spray powders, pastes, soluble powders, dusting agents, and granules. The application is performed in the typical way, e.g., through pouring, spraying, scattering, dusting, foaming, painting, etc. Furthermore, it is possible to apply the active ingredients according to the ultralow volume method or inject the active ingredient preparation or the active ingredient itself into the soil. The seed of the plants may also be treated.


When using the active ingredients according to the present invention as fungicides, the applied quantities may be varied within a wide range depending on the type of application. When treating plant parts, the applied quantities of active ingredient are generally between 0.1 and 10,000 g/hectare, preferably between 10 and 1000 g/hectare. When seeds are treated, the applied quantities of active ingredient are generally between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 10 g per kilogram of seed. When treating the soil, the applied quantities of active ingredient are generally between 0.1 and 10,000 g/hectare, preferably between 1 and 5000 g/hectare.


As already noted above, all plants and their parts may be treated according to the present invention. In a preferred embodiment, types of plants and plant species occurring wild or obtained through conventional biological cultivation methods, such as breeding or protoplast fusion, as well as their parts, may be treated. In a further preferred embodiment, transgenic plants and plant species which were obtained through methods of genetic engineering, optionally in combination with conventional methods (genetically modified organisms) and their parts are treated. The term “parts” and/or “parts of plants” or “plant parts” was explained above.


According to the present invention, plants of the particular commercially available plant species or plant species in use are especially preferably treated. Plant species are understood as plants having new properties (“traits”), which may be cultivated both through conventional cultivation, through mutagenesis, or through recombinant DNA technologies. These may be species, breeds, biotypes, and genotypes.


Depending on the plant types and/or plant species, their location and growth conditions (soil, climate, vegetation period, nutrition), (“synergistic”) effects may also arise through the treatment according to the present invention. Thus, for example, lowered applied quantities and/or expansions of the activity spectrum and/or an amplification of the effect of the materials and agents usable according to the present invention, better plant growth, elevated tolerance to high or low temperatures, elevated tolerance drought or to water and/or soil salinity, elevated blooming performance, easier harvesting, acceleration of ripening, higher harvest yields, higher quality and/or higher nutritional value of the harvested products, greater storage capability and/or processability of the harvested products are possible, which exceed the actual effects to be expected.


The preferred transgenic (obtained through genetic engineering) plants and/or plant species to be treated according to the present invention include all plants which have obtained genetic material through genetic modification which provides these plants with especially advantageous valuable properties (“traits”). Examples of such properties are better plant growth, elevated tolerance to high or low temperatures, elevated tolerance to drought or to water and/or soil salinity, elevated blooming performance, easier harvesting, acceleration of ripeness, elevated harvest yields, greater storage capability and/or processability of the harvested products. Further and especially pronounced examples of such properties are elevated defence of the plants against animal and microbial pests, for example, against insects, mites, phytopathogenic fungi, bacteria, and/or viruses, as well as elevated tolerance of the plants to specific herbicidal active ingredients. Examples of transgenic plants include the important cultured plants, such as grains (wheat, rice), maize, soya, potatoes, cotton, tobacco, rapeseed, as well as fruit plants (having the fruits apples, pears, citrus fruits, and grapes), maize, soya, potatoes, cotton, tobacco, and rapeseed being noted in particular. The elevated defence of the plants to insects, arachnids, nematodes, and snails through toxins arising in the plants, particularly those which are generated in the plants by the genetic material of Bacillus thuringiensis (e.g., for example, by the genes CryIA(a), CryIA(b), CryIA(c), CryIIA, CryIIIA, CryIIIB2, Cry9c Cry2Ab, Cry3Bb and CryI, as well as their combinations) are especially to be noted (referred to in the following as “Bt plants”). The elevated defences of plants against fungi, bacteria, and viruses through systemic acquired resistance (SAR), systemin, phytoalexines, elicitors, and resistance genes and correspondingly expressed proteins and toxins are also especially noted as properties (“traits”). The elevated tolerance of the plants to specific herbicidal active ingredients, such as imidazolinones, sulphonyl ureas, glyphosates, or phosphinotricine (e.g., “PAT” gene) is also especially to be noted. The particular genes which provide the desired properties (“traits”) may also occur in the transgenic plants in combination with one another. Examples of “Bt plants” are maize varieties, cotton varieties, soya varieties, and potato varieties which are distributed under the trade names YIELD GARD® (e.g., maize, cotton, soya), KnockOut® (e.g., maize), StarLink® (e.g., maize), Bollgard® (cotton), Nucoton® (cotton) and NewLeaf® (potato). Examples of plants tolerant to herbicides are maize varieties, cotton varieties and soya varieties, which are distributed under the trade names Roundup Ready® (tolerance to glyphosates, e.g., maize, cotton, soya), Liberty Link® (tolerance to phosphinotricine, e.g., rapeseed), IMI® (tolerance to imidazolinones), and STS® (tolerance to sulphonyl ureas, e.g., maize). The varieties (e.g., maize) of plants resistant to herbicides (conventionally cultivated for herbicide tolerance) distributed under the trade name Clearfield® are also noted. Of course, the statements also apply for plant varieties developed in the future and/or coming to market in the future having these genetic properties (“traits”) or those developed in the future.


The plants listed may be treated especially advantageously according to the present invention using the compounds of the general formula (I) and/or the active ingredient mixtures according to the present invention. The preferred ranges specified above for the active ingredients and/or mixtures also apply for the treatment of these plants. The plant treatment using the compounds and/or mixtures specially listed in the present text is especially noted.


The production and the use of the active ingredients according to the present invention is described in the following examples.
