る。Among the groups represented by the formula, particularly preferred are methylene, ethylidene, isopropylidene, cyclohexylidene, benzylidene, and the like. In addition to the above, as the group represented by R', any group commonly used as a protecting group for hydroxyl groups can be used, and all such R's may be the same group, two types or It may be more than one different group. Among the above, a particularly preferable group of derivatives is one in which aR' is a hydrogen atom, and eight or more of R' are groups arbitrarily selected from lower acyl such as an acetyl group, a propionyl group, and a butyryl group. , and the remaining groups are hydrogen atoms, bR is a hydrogen atom, and 2 to 10 of R' are optionally
Two R's are combined to form 1 to 5 isopropylidene groups or cyclohexylidene groups,
and a derivative in which the remaining groups are hydrogen atoms or groups arbitrarily selected from acetyl groups, cR is a hydrogen atom, and 8 or more of R' are methyl groups,
and the remaining groups are hydrogen atoms, dR
is a formyl group, R′ is a lower acyl group such as a formyl group, an acetyl group, a propionyl group, or a derivative represented by a group arbitrarily selected from a hydrogen atom, and eR is a substituted carbamoyl group,
Examples include derivatives in which R' is a substituted carbamoyl group, a lower acyl group such as a formyl group, an acetyl group, a propionyl group, or a group arbitrarily selected from a hydrogen atom. The derivative represented by the general formula [] is produced by a method known per se in the field of organic chemistry using validamycin A (hereinafter abbreviated as VM-A) as a raw material. That is, a carboxylic acid halide or anhydride is added to VM-A in the presence of an inorganic or organic base such as sodium hydroxide, potassium hydroxide, sodium acetate, pyridine, or quinoline, and in some cases concentrated sulfuric acid or zinc chloride. An acyl derivative can be obtained by esterifying the hydroxyl group by reaction. For example, hydroxyl groups can be completely acetylated by heating with acetic anhydride in pyridine at 60 to 70°C for 2 to 3 hours. Furthermore, by gently reacting with formic acid-acetic anhydride in pyridine at room temperature, for example, hydroxyl groups can be completely formylated, and secondary amino groups can also be formylated at the same time. Similarly, sulfonic acid esterification was carried out by a conventional method.
By performing carbonate esterification and carbamate esterification, the corresponding acyl derivatives can be produced. For example, hydroxyl groups can be partially sulfonylated by mildly reacting p-toluenesulfonyl chloride in pyridine at low temperatures. For example, hydroxyl groups can be completely ethoxycarbonylated by heating with ethyl chlorocarbonate in pyridine for several hours. For example, all hydroxyl groups can be phenylcarbamoylated by reacting with phenyl isocyanate in pyridine at room temperature for a long time, and secondary amino groups can also be carbamoylated at the same time. A dioxolane ring or a 1,3-
A cyclic acetal such as a dioxane ring can be obtained, and in some cases, a hemiacetal can also be obtained at the same time. For example, in dimethylformamide (DMF), using p-toluenesulfonic acid as a catalyst, 2,2-dimethoxypropane and 70 to 80
Partial isopropylideneation can be achieved by heating for several hours at °C. In addition, VM-A can be added to alkyl or aralkyl in the presence of an organic or inorganic base such as pyridine, sodium hydroxide, potassium hydroxide, lithium hydroxide, or barium hydroxide, or a metal oxide such as silver oxide or barium oxide. The hydroxyl group can be etherified by reacting with a halide, an alkyl sulfate, or the like. For example, when methyl iodide is applied in the presence of barium oxide in DMF, hydroxyl groups can be completely methylated under mild conditions at 35 to 40°C. Further, for example, only the primary hydroxyl group can be tritylated by reacting trityl chloride in pyridine. In the above method, by appropriately selecting the type of reaction reagent, the amount of reaction reagent used, reaction conditions such as reaction temperature, reaction time, etc., completely substituted products with functional groups,
Alternatively, a partially substituted product in which some functional groups remain can be optionally produced. Furthermore, if desired, for partially substituted products, the same method as above can be repeated to obtain a second,
A third group can be introduced. Then, if necessary, the first substituent is selectively removed by appropriate chemical means such as hydrolysis with an acid or alkali, reduction, etc., and only the functional group at a specific position is converted into a desired group. Compounds substituted with can be obtained. For example, after treating VM-A with trityl chloride to tritylate only the primary hydroxyl groups, the remaining hydroxyl groups are then acetylated with acetic anhydride in pyridine, and then this is further acetylated with hydrobromic acid in acetic acid. When hydrolyzed, the trityl group is selectively eliminated, and only the secondary hydroxyl group is acetylated.
A derivative is obtained. Introduction of a substituent to a secondary amino group can be carried out simultaneously with introduction to a hydroxyl group, or can be carried out after introducing another substituent to a hydroxyl group. In particular, when a partially substituted secondary hydroxyl group of VM-A is produced by the above method, it is often obtained as a mixture of positional isomers and those having different numbers of substituents. Various methods are used for these isolations and purifications, but chromatography using a silica gel column is particularly simple and effective. Further, the progress of the reaction can be determined by various methods, but for example, a method of tracking using silica gel thin layer chromatography is suitable. The validamycin A derivative represented by the general formula [] obtained above exhibits a high control effect over a long period of time, even in non-sterilized soil, against, for example, seedling blight, and is also effective against, for example, rice sheath blight. It also shows superior long-lasting effects without impairing the action and characteristics of VM-A. The VM-A derivatives of the present invention can be used alone or as a mixture of two or more in any ratio depending on the application. The agricultural fungicide of the present invention can be prepared by applying such a VM-A derivative directly, dissolving or dispersing it in a suitable liquid carrier, or mixing it with a suitable solid carrier, depending on the purpose of use. It may be applied as appropriate. If desired, emulsifiers, dispersants, suspending agents, adsorbents, penetrants, wetting agents, mucilage agents, stabilizers, excipients, bulking agents, etc. may be added to this to form oils, emulsions, and wettable powders. It may be used in the form of aqueous solutions, liquids, powders, tablets, granules, sprays, and the like. The appropriate content of the substance of the present invention is about 0.5 to 80% for emulsions, hydrating agents, etc.
A suitable concentration for powders and the like is about 0.01 to 20%, but these concentrations may be changed as appropriate depending on the purpose of use. When using emulsions, hydrating agents, etc., dilute and increase the volume with water as appropriate (for example, 160 to 5000
It is best to double the amount and spread it. Furthermore, these drugs include not only validamycin A, but also validamycin B, C, DEF, and validoxylamine A or B.
Or other types of fungicides, such as copper-based fungicides, organic sulfur-based fungicides, organochlorine-based fungicides, organophosphorus-based fungicides, antibiotics, etc., or insecticides such as organochlorine-based insecticides, organophosphorus-based insecticides, etc. , carbamic acid insecticides, natural insecticides, etc. may be appropriately blended or used in combination. Next, the present invention will be explained with reference to production examples, formulation examples, and test examples of anti-rhizoctonia disease effects of the derivatives of the present invention. Compound numbers correspond to compound numbers in the table.
