The present invention relates to novel cyclopenta[c]isoxazole-3-amines, to processes for their preparation, to their use for controlling unwanted microorganisms and to novel mixtures of cyclopenta[c]isoxazole-3-amines with other active compounds.
Very few cyclopenta[c]isoxazole-3-amines are known from the literature (cf. G. Gerali et al., Farmaco Edizione Scientifica 1969, 24, 1105-1114), and an action against material-destroying organisms has not been described.
We have found novel cyclopenta[c]isoxazole-3-amines which, surprisingly, have excellent bactericidal action. Owing to their antibacterial and antifungal action, the novel cyclopenta[c]isoxazole-3-amines are, on their own or in a mixture with one another, particularly suitable for controlling microorganisms in and on industrial materials.
The present invention provides cyclopenta[c]isoxazole-3-amines of the formula (I)

in which
In the definitions of the substituents R1 to R8, the saturated or unsaturated hydrocarbon radicals, such as alkyl, alkenyl or alkynyl, are in each case straight-chain or branched and unsubstituted or mono- to polysubstituted by identical or different substituents, including in combination with heteroatoms, such as in alkoxy, haloalkoxy, haloalkylthio or alkylthio, and in composite terms, such as alkyl- or dialkylamino.
In the alkyl- and dialkylamino substituents mentioned, the alkyl radicals can in each case be identical or different.
Aryl represents aromatic mono- or polycyclic hydrocarbon rings which are unsubstituted or mono- to polysubstituted by identical or different substituents, such as, for example, phenyl, naphthyl, anthranyl, phenanthranyl, preferably phenyl or naphthyl, in particular phenyl.
In the terms haloalkyl, haloalkoxy and haloalkylthio, the halogen atoms can in each case be identical or different. Halogen represents generally fluorine, chlorine, bromine, in particular fluorine or chlorine.
Heterocyclyl represents saturated and unsaturated and also aromatic cyclic compounds in which at least one ring member is a heteroatom, i.e. an atom different from carbon, which compounds are unsubstituted or mono- to polysubstituted by identical or different substituents. If the ring contains a plurality of heteroatoms, these can be identical or different. Preferred heteroatoms are oxygen, nitrogen or sulfur. If appropriate, the cyclic compounds form, together with further carbocyclic or heterocyclic fused-on or bridged rings, a polycyclic ring system. A polycyclic ring system may be attached via the heterocyclic ring or a fused-on carbocyclic ring. Preference is given to mono- or bicyclic ring systems, in particular mono- or bicyclic aromatic ring systems. Preferred heterocyclyl radicals are pyridyl, pyrimidyl, thienyl, furyl and pyrryl.

The compounds of the formulae (I) and (II) according to the invention have potent microbicidal action and can be used for controlling unwanted microorganisms, such as fungi and bacteria, in crop protection and in the protection of materials.
In the protection of materials, the substances according to the invention can be used for protecting industrial materials against attack and destruction by undesirable microorganisms. In the present context, industrial materials are to be understood as meaning non-living materials which have been prepared for use in industry. For example, industrial materials which are intended to be protected by active compounds according to the invention from microbial change or destruction can be glues, sizes, paper and board, textiles, leather, wood, paints and synthetic articles, cooling lubricants and other materials which can be attacked or destroyed by microorganisms. Parts of production plants, for example cooling-water circuits, which may be impaired by the multiplication of microorganisms may also be mentioned in the context of the materials to be protected. Industrial materials which may preferably be mentioned in the context of the present invention are glues, sizes, paper and boards, leather, wood, paints, cooling lubricants and heat transfer liquids.
Examples of microorganisms which are capable of bringing about degradation of, or change in, the industrial materials and which may be mentioned are bacteria, fungi, yeasts, algae and slime organisms. The active compounds according to the invention preferably act against fungi, in particular moulds, wood-discolouring and wood-destroying fungi (Basiidiomycetes) and also against slime organisms and bacteria.
Microorganisms of the following genera may be mentioned by way of example:
Altemaria, such as Altemaria 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.
The compounds (I) according to the invention can, on their own or in any mixture with one another, be used for protecting industrial materials.
Depending on their respective physical and/or chemical properties, the compounds according to the invention or mixtures thereof can be converted into customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols and very fine capsules in polymeric substances.
These formulations and compositions are prepared in a known manner, for example by mixing the active compounds with extenders, that is, liquid solvents, liquefied gases under pressure, and/or solid carriers, if appropriate with the use of surfactants, that is emulsifiers and/or dispersants and/or foam-formers. If the extender used is water, it is also possible to use for example organic solvents as auxiliary solvents. Essentially, suitable liquid solvents are: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylene or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example mineral oil fractions, alcohols, such as butanol or glycol and their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethyl formamide and dimethyl sulfoxide, and water. By liquefied gaseous extenders or carriers are meant liquids which are gaseous at ambient temperature and under atmospheric pressure, for example aerosol propellants, such as halogenated hydrocarbons and butane, propane, nitrogen and carbon dioxide. Suitable solid carriers are: for example ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as finely divided silica, alumina and silicates. Suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, and synthetic granules of organic and inorganic meals, and granules of organic material such as sawdust, coconut shells, maize hobs and tobacco stalks. Suitable emulsifiers and/or foam-formers are: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulfonates, alkyl sulfates, arylsulfonates and protein hydrolysates. Suitable dispersants are: for example lignin-sulfite waste liquors and methylcellulose.
Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, and natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Possible further additives are mineral and vegetable oils.
It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanin dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
The formulations generally comprise between 0.1 and 95% by weight of active compound or active compound mixture, preferably between 2 and 75% by weight.
The present invention furthermore provides microbicidal compositions based on the compounds according to the invention, which compositions comprise at least one solvent or diluent and, if appropriate, processing auxiliaries and, if appropriate, further antimicrobially active substances.
The efficacy and the activity spectrum of the active compounds of the formulae (I) and (II) and of the compositions preparable therefrom, of precursors or of formulations in general can be increased by adding, if appropriate, further antimicrobial compounds, fungicides, bactericides, herbicides, insecticides or other active compounds, so as to widen the spectrum of activity or to obtain particular effects such as, for example, additional protection against insects. These mixtures may have a wider activity spectrum than the compounds according to the invention.
