Herbicides for citrus oil palm rubber and other plantation crops

FIELD OF THE INVENTION
This invention relates to novel substituted heterocyclic compounds and a method for controlling undesired vegetation in crops including plantation and specialty crops. Some of the compounds of the instant invention have been disclosed previously for use generally as herbicides, but these disclosures provide no teachings for use of these compounds as herbicides in plantation crops.
BACKGROUND OF THE INVENTION
U.S. Pat. No. 4,859,229 discloses herbicidal utility in "cotton and soya" cultivations for compounds of the formula ##STR1## wherein, inter alia R.sup.1 is H, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 haloalkyl, formyl or C.sub.2 -C.sub.6 alkanoyl;
R.sup.2 is (in part) an ether group;
R.sup.3 is H or CN;
R.sup.4 is H or halogen;
R.sup.5 is H, halogen or C.sub.1 -C.sub.4 alkyl;
R.sup.6 is C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 haloalkyl; and
R.sup.5 and R.sup.6 together are tri- or tetramethylene.
The instant invention provides a method for controlling undesired vegetation in plantation and specialty crops. Many of the compounds of the instant invention have been previously disclosed for use generally as herbicides, and such disclosures are found in U.S. Pat. No. 4,859,229, EP-A-438,209, JP 3-77,874 and EP-A-408,382. There are, however, no teachings for the use of these compounds as herbicides in plantation and specialty crops such as citrus, sugarcane, coffee, banana, oil palm, loblolly pine, rubber, cocoa, grapes, plantain, pineapple, fruit trees such as apples, and nut trees. These crops are important markets and are cultivated particularly in regions of the Pacific rim and South America. Citrus, sugarcane and loblolly pine also are grown elsewhere.
The yields of selected crops such as citrus, sugarcane, coffee, banana, oil palm, loblolly pine, rubber, cocoa, grapes, fruit trees and Bermudagrass tend to be lessened by undesired plantings such as crabgrass, johnson grass, guineagrass and the like. In addition, the yields of these crops tend to be reduced by crop plants such as corn, cotton, wheat, rice, and the like. A need therefore exists for controlling these types of plantings to improve the yields of selected crops such as those mentioned above.
This invention also provides novel substituted heterocyclic compounds and their agriculturally suitable compositions which are generally useful as herbicides, as well as methods of their use as general or selective preemergent or postemergent herbicides, or as plant growth regulants.
New compounds effective for controlling the growth of undesired vegetation are in constant demand. In the most common situation, such compounds are sought to selectively control the growth of weeds in useful crops such as sugarcane, citrus, oil palm, cotton, rice, corn, wheat and soybeans, to name a few. Unchecked weed growth in such crops can cause significant losses, reducing profit to the farmer and increasing costs to the consumer. In other situations, herbicides are desired which will control all plant growth. Examples of areas in which complete control of all vegetation is desired are areas around railroad tracks, storage tanks and industrial storage areas. There are many products commercially available for these purposes, but the search continues for products which are more effective, less costly and environmentally safe.

DETAILED DESCRIPTION OF THE INVENTION
Many of the compounds of Formula I wherein Z and R.sup.2 are not taken together can be prepared according to the procedures of U.S. Pat. No. 4,859,229 and U.S. Pat. No. 3,902,887, the disclosures of which are herein incorporated by reference.
Schemes 1 to 4 illustrate the preparation of compounds of Formula II wherein Z and R.sup.2 are taken together. ##STR7##
The dihydrofuran ring of compounds of Formula II can be prepared according to the procedure of U.S. Pat. No. 4,881,967 by Claisen rearrangement of allyl ether VII followed by cyclization as shown in Scheme 1, Equations (c) and (d). The rearrangement and cyclization normally require high temperatures ranging from 100.degree. C. to 200.degree. C. Therefore, it is preferable to perform this process at an early stage with an inert protecting group on nitrogen. For this reason, phthalimide VII is prepared via treatment of hydroxyaniline V with phthalic anhydride IV followed by allylation of the hydroxy group of VI in the presence of a weak base such as potassium carbonate (Scheme 1, Equations (a) and (b)).
Alternatively, the compound VII can be prepared by allylation of V first followed by treatment with phthalic anhydride IV.
The rearrangement of VII can be effected by heating in an inert solvent such as N,N-dimethylaniline or .omicron.-dichlorobenzene at a temperature of about 100.degree. C. to 200.degree. C. This Claisen rearrangement can also proceed with titanium tetrachloride and N-trimethylsilyl-acetanilide at ambient temperature in an inert solvent such as dichloromethane (Narasaka, K., Bald E., and Mukaiyama T.; Chemistry Letters 1975, 1041). The cyclization of VIII to give IXa can be effected by refluxing a solution of phenol VIII in an inert solvent, such as xylene, containing a catalytic to stoichiometric amount of acid such as p-toluenesulfonic acid under Dean-Stark apparatus at a temperature range of from about 120.degree. C. to 180.degree. C. (Scheme 1, Equation (d)). ##STR8##
For the preparation of dihydrothiophene IXb, the allylphenol VIII is treated with N,N-dimethylthiocarbamoyl chloride in the presence of a weak base such as potassium carbonate in an inert solvent such as acetone or N,N-dimethylformamide at a temperature between 0.degree. C. and refluxing temperatures of the solvents over several hours as shown in Scheme 2a, Equation (a).
Thermal rearrangement of X may be effected in a suitable inert solvent such as .omicron.-dichlorobenzene at 150.degree.-250.degree. C. to produce carbamate derivative XI. Cyclization of XI with an anhydrous acid such as hydrogen bromide in acetic acid at refluxing temperatures affords IXb as shown in Scheme 2a, Equation (c).
The acetylene substituted dihydrofuran ring of compounds of Formulas II and III (i.e., R.sup.9 is C.sub.2 alkynyl) can be prepared as shown in Scheme 2b. ##STR9##
The hydroxyl group of VIII of Scheme 1, Equation (c) can be protected by a silicon protecting group using reagents such as trimethylsilyl chloride or t-butyldimethylsilyl chloride to give XXXIV. Then the reductive ozonolysis of XXXIV gives aldehyde XXXV. The diol XXXVI can be prepared by the treatment of aldehyde XXXV with lithium salt of trimethylsilylacetylene. The deprotections of both silyl protecting groups of XXXVI can be accomplished using fluoride ions such as potassium fluoride. The acetylenic hydrofuran XXXVIII can be prepared from the diol XXXVII by Mitsunobu condition using diethyl azodicarboxylate (DEAD) and triphenylphosphine according to the known procedure (Macor, J., Ryan, K., and Newman, M.; Tetrahedron 1992, 48, 1039).
The vinyl group substituted dihydrofuran ring of compounds of Formula XI and III can be prepared as shown in scheme 2c. ##STR10##
The hydroxymethyl hydrofuran XXXIX can be prepared by treatment of VIII with m-chloroperbenzoic acid (MCPBA) followed by p-toluenesulfonic acid. The treatment of XXXIX with carbon tetrabromide and triphenylphosphine gives bromomethyl hydrofuran XL. The Wittig reagent XLI can be prepared by the treatment of XL with triphenylphosphine in an inert solvent such as DMF. The vinylic hydrofuran XLII can be prepared by Wittig reaction of XLI and formaldehyde.
The hydroxy group of XXXIX can be converted to ketone, carboxylic acid, ester or amide groups by methods well known to those skilled in the art. This transformation can be carried out before or after the phthalimide protecting group is removed. If the protecting group is removed first, then the unprotected aniline derivative is first converted to the uracil or triazinedione ring (as described later) before further conversion of the hydroxyl group. ##STR11##
The phthalimide protecting group of IXa or IXb can be removed by hydrazine at ambient temperature to afford aniline XII. The formation of isocyanate XIII is accomplished by treatment of the aniline XII with phosgene or triphosgene in the presence of a base such as triethylamine at ambient temperature, or without base in an inert solvent such as dioxane or toluene at a temperature range of from 60.degree. C. to 120.degree. C. (Scheme 3). ##STR12##
The formation of the uracil ring in compound XV is carried out by the procedure described in U.S. Pat. No. 4,943,309. A suitable salt of an enamine XIV is treated with the isocyanate XIII at low temperature over several hours, typically between -50.degree. C. and -70.degree. C. in an inert solvent such as toluene, and the reaction is continued at ambient temperature for several hours. The alkylation of XV can be accomplished by treatment of XV with C.sub.1-4 alkyl halide, or C.sub.1-4 haloalkyl halide, especially the respective chloride or bromide, or sulphate in the presence of a base such as potassium carbonate or sodium hydride in an inert solvent such as acetone or acetonitrile at a temperature range of from about 0.degree. C. to 120.degree. C. The acylation of XV is carried out with acetic anhydride or a C.sub.2-6 alkanecarboxylic acid halide, in the presence of base such as sodium hydride.
Schemes 5 and 6 illustrate the preparation of compounds of Formula III. ##STR13##
The formation of the triazinedione ring follows the procedure described in U.S. Pat. No. 3,902,887 when R.sup.3 is a dimethylamino group as shown in Scheme 5. N-Ethoxy-carbonylguanidine XVI is mixed with an isocyanate XVII in an inert solvent, preferably toluene, while the temperature is maintained at 25.degree. C. to 100.degree. C., preferably 55.degree. C. to 80.degree. C. The mixture of slurry containing compound XVIII is cooled, if necessary, to 24.degree. C.-45.degree. C., while dimethylamine is added, either as a gas or a liquid. It is preferred to add the amine at 25.degree.-35.degree. C., and it is important to have at least 1.0 molar equivalent and preferably, 1.0 to 2.5 molar equivalents of dimethylamine. Next a ring closure catalyst is added. The catalyst is an alkali metal alkoxide (or hydroxide) and it may be added either as a dry solid or as a solution in the alkanol. Dry sodium methoxide or a solution of sodium methoxide in methanol is a preferred catalyst. The amount of catalyst needed is from 0.1 to 5.0 mole percent of compound XVIII. The ring closure reaction can proceed at a temperature between 0.degree. C. and 120.degree. C. The reaction is rapid and normally complete in less than several hours. ##STR14##
When R.sup.3 is C.sub.1 -C.sub.4 alkyl and C.sub.1 -C.sub.4 haloalkyl substituents, the formation of the triazinedione ring follows the procedure described by JP 03 77,874 as shown in Scheme 6. Carbamoylation of alkylamidine hydrochloride or haloalkylamidine hydrochloride XIX with isocyanate XVII under the condition described in Scheme 5 or in the presence of NaOH in aqueous acetone gives N-phenylcarbamoyl amidine XX. The cyclocondensation of the resulting compound XX with ethyl chloroformate in the presence of base such as sodium hydride or sodium methoxide in an inert solvent such as tetrahydrofuran gives triazinedione XXII via XXI. The alkylation of XXII can be accomplished by treatment of XXII with C.sub.1-4 alkyl halide, or C.sub.1 -C.sub.4 haloalkyl halide, especially the respective chloride, bromide or sulphate in the presence of a base such as potassium carbonate or sodium hydride in an inert solvent such as acetone or acetonitrile at a temperature range of from about 0.degree. C. to 120.degree. C. The acylation of XXII is carried out with acetic anhydride or a C.sub.2 -C.sub.6 alkanecarboxylic acid halide in the presence of base such as sodium hydride. ##STR15##
Compounds of Formula II wherein Z is hydrogen and A is oxygen can be prepared according to Scheme 7. Cyclocondensation of enamine XIV can be carried out with benzyl ether protected isocyanate XXIII. The enamine XIV wherein R.sup.3 and R.sup.4 are taken together as --(CH.sub.2).sub.3 -- or --(CH.sub.2).sub.4 -- can be prepared according to the known procedure (Kloek, J., and Leschinsky, K.; J. Org Chem., 1978, 43, 1460). Other enamines of Formula XIV wherein R.sup.3 and R.sup.4 are not taken together can be prepared by one skilled in the art. The resultant uracil XXIV is alkylated or acylated as described previously and benzyl ether XXV can be deprotected easily with 5 to 10% palladium on charcoal under hydrogen pressure ranging from 20 to 50 psi. The resulting phenol XXVI is treated with C.sub.1 -C.sub.4 alkyl halide, or C.sub.1 -C.sub.4 haloalkyl halide, especially the respective chloride or bromide in the presence of a base such as potassium carbonate or sodium hydride in an inert solvent such as acetone or acetonitrile at a temperature range of from about 0.degree. C. to 120.degree. C. to give XXVII. ##STR16##
The compound XXX which has two identical R.sup.10 substituents (wherein R.sup.10 is isopropyl, allyl or C.sub.3 -C.sub.4 alkynyl) can be prepared by deprotection of benzyl ether XXIV with palladium on charcoal under hydrogen followed by alkylation or acylation in the presence of base as shown in Scheme 8. ##STR17##
The same procedure can be adopted for the synthesis of triazinediones of Formula III wherein Z is hydrogen and A is oxygen as shown in Scheme 9. The cyclocondensation product XXXI from N-ethoxycarbonylguanidine XVI and benzyl ether protected isocyanate XXIII is treated with palladium on charcoal under hydrogen pressure ranging from 20 to 50 psi followed by alkylation or acylation in the presence of base to give XXXIII.

Formulation
Compounds of this invention will generally be used in formulation with an agriculturally suitable carrier comprising a liquid or solid diluent or an organic solvent. Use formulations include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates, dry flowables and the like, consistent with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature. Sprayable formulations can be extended in suitable media and used at spray volumes from about one to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations will typically contain effective amounts of active ingredient, diluent and surfactant within the following approximate ranges which add up 100 weight percent.

Typical solid diluents are described in Watkins, et al., Handbook of Insecticide Dust Diluents and Carriers, 2nd Ed., Dorland Books, Caldwell, N.J. Typical liquid diluents and solvents are described in Marsden, Solvents Guide, 2nd Ed., Interscience, New York, 1950. McCutcheon's Detergents and Emulsifiers Annual, Allured Publ. Corp., Ridgewood, N.J., as well as Sisely and Wood, Encyclopedia of Surface Active Agents, Chemical Publ. Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth, etc.
Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer mill or fluid energy mill. Water-dispersible granules can be produced be agglomerating a fine powder composition; see for example, Cross et al., Pesticide Formulations, Washington, D.C., 1988, pp 251-259. Suspensions are prepared by wet-milling; see, for example, U.S. Pat. No. 3,060,084. Granules and pellets can be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See Browning, "Agglomeration" Chemical Engineering, December 4, 1967, pp 147-48, Perry's Chemical Engineer's Handbook, 4th Ed., McGraw-Hill, New York, 1963, pages 8-57 and following, and WO 91/13546. Pellets can be prepared as described in U.S. Pat. No. 4,172,714. Water-dispersible and water-soluble granules can also be prepared as taught in DE 3,246,493.

TEST B
The compounds evaluated in this test were formulated in a non-phytoxic solvent and applied to the soil surface before plant seedlings emerged (preemergence application), to water that covered the soil surface (flood application), and to plants that were in the one-to-four leaf stage (postemergence application). A sandy loam soil was used for the preemergence and postemergence tests, while a silt loam soil was used in the flood test. Water depth was approximately 2.5 cm for the flood test and was maintained at this level for the duration of the test.
Plant species in the preemergence and postemergence tests consisted of barley (Hordeurn vulgare), bedstraw (Galium aparine), blackgrass (Alopecurus myosuroides), chickweed (Stellaria media), corn (Zea mays), cotton (Gossypium hirsutum), crabgrass (Digitaria sanguinalis), downy brome (Bromus rectorurn), giant foxtail (Setaria faberii), lambsquarters (Chenopodium album), morningglory (Ipomoea hederacea), pigweed (Amaranthusretroflexus), rape (Brassica napus), ryegrass (Lolium multifiorum), sorghum (Sorghum bicolor), soybean (Glycine max), speedwell (Veronica persica), sugar beet (Beta vulgaris), velvetleaf (Abutilon theophrasti), wheat (Triticum aestivum), wild buckwheat (Polygon urn convolvulus), and wild oat (Avena fatua).
All plant species were planted one day before application of the compound for the preemergence portion of this test. Plantings of these species were adjusted to produce plants of appropriate size for the post-emergence portion of the test. Plant species in the flood test consisted of barnyardgrass (Echinochloa crus-galli), rice (Oryza sativa), umbrella sedge
(Cyperus difformis) and duck salad (Heteranthera limosa). All plant species were grown using normal greenhouse practices. Visual evaluations of injury expressed on treated,plants, when compared to untreated controls, were recorded approximately fourteen to twenty one days after application of the test compound. Plant response ratings, summarized in Table B, were recorded on a 0 to 100 scale where 0 is no effect and 100 is complete control. A dash (--) response indicates no test result.

TEST C
Compounds evaluated-in this test were formulated in a non-phytoxic solvent and applied to the soil surface before plant seedlings emerged (preemergence application) and to plants that were in the one-to-four leaf stage (postemergence application). A sandy loam soil was used for the preemergence test while a mixture of sandy loam soil and greenhouse potting mix in a 60:40 ratio was used for the postemergence test. Test compounds were applied within approximately one day after planting seeds for the preemergence test.
Plantings of these crops and weed species were adjusted to produce plants of appropriate size for the postemergence test. All plant species were grown using normal greenhouse practices. Crop and weed species include winter barley (Hordeurn vulgate cv. `Igri`), blackgrass (Alopecurus myosuroides), chickweed (Steliaria media), downy brome (Bromus tectorum), field violet (Viola arvensis), galium (Galium aparine), green foxtail (Setaria viridis), kochia (Kochia scoparia), lambsquarters (Chenopodium album), speedwell (Veronica persica), rape (Brassica napus), ryegrass (Lolium multiflorum), sugar beet (Beta vulgaris cv. `US1`), sunflower (Helianthus annuus cv. `Russian Giant`), spring wheat (Triticum aestivum cv. `ERA`), winter wheat (Triticum aestivum cv. `Talent`), wild buckwheat (Polygonurn convolvulus), wild mustard (Sinapis arvensis), wild oat (Avena fatua), and wild radish (Raphanus raphanistrum).
Blackgrass, galium and wild oat were treated at two growth stages. The first stage (1) was when the plants had two to three leaves. The second stage (2) was when the plants had approximately four leaves or in the initial stages of tillering. Treated plants and untreated controls were maintained in a greenhouse for approximately 21 to 28 days, after which all treated plants were compared to untreated controls and visually evaluated. Plant response ratings, summarized in Table C, are based upon a 0 to 100 scale where 0 is no effect and 100 is complete control. A dash response (--) indicates no test result.

TEST L
Rooted cuttings of rough lemon (Citrus sp.) were planted in 30 liter plastic pots. These pots were also seeded with guineagrass (Panicum maximum), sandbur (Cenchrus enchinatus) and pigweed (Amaranthus viridis). The weeds were cutback many times to simulate mowing and the citrus plant also trimmed.
The citrus was sprayed to simulate field type post-directed herbicide application while the weeds were treated postemergence over the top with the test compounds formulated in a non-phytotoxic spray solvent. In a separate test, loblolly pine seedlings were also sprayed over-the-top with the test compounds formulated in a non-phytotoxic spray solvent. Treated plants were visually rated and compared with appropriate controls. The injury ratings are based on the scale of 0 to 100 where 0 indicates no effect, 20 indicates minimal effect and 100 indicates complete control. The results are shown in Tables L1 and L2. The differences in results may be due to the fact that the tests were conducted using plants at different stages of growth.
