Description: IIX E HERBICIDAL SULFONYLUREAS Cross-reference to Related Application This is a continuation-in-part of USSN 07/468,283 filed January 22, 1990. Background of the Invention This invention relates to certain herbicidal sulfonylureas, agriculturally- suitable compositions thereof and a method for 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 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. EP-A-238,070 discloses herbicidal sulfonylureas of the general formula wherein: Q is a condensed heterocyclic group having an N atom in the bridgehead, which may be substituted.

Protecting group removal induces cyclization to sulfonamides 1£. Preparation of sulfonamides 4. where L is L-11 may be achieved through the sequence outlined in Equation 10, wherein R 1 , R 19 , X 5 and W are as previously defined. Equation 10 1 9 20 21 Sulfonamide of Formula 2 may be alkylated on nitrogen with a suitable electrophilic reagent containing a disulfide using conditions described in Equation 6 to afford intermediates 12.. Metalation of 12. results in cyclization to cyclic sulfide 2£ which can then be further oxidized with a suitable oxidant such as a peroxy acid or hydrogen peroxide to sulfoxides (m - 1) or sulfones (m ■ 2). Sulfonamide protecting group removal affords bicyclic sulfonamides 21.

Removal of protecting group R 20 , followed by treatment with base, as needed, induces cyclization to sulfonamides 24. Sulfonamides of Formula ___ where L is L-15 may be prepared as outlined in Equation 12, wherein R 19 is tert-alkyl, R 6 is H or alkyl, and R 22 is a trialkylsilyl protecting group.

Equation 13 li_ 2 β _ (R*=R 4 =I0 29 The ketone 14., wherein R 3 -R 4 -H, described in Equation 8 can be further treated with reducing agents such as borohydrides, aluminum hydrides and the like to afford the corresponding alcohols 23.- Conversion of this alcohol to a variety of derivatives such as halides, ethers, esters, sulfonates as encompassed by R 6 may then be achieved by standard methods widely known in the art. Pyrrole-3-sulfonamide precursors 2 wherein W-CH, R «H and R 9 is a suitable protecting group as defined above are available from the corresponding bromo pyrrole ££ as depicted in Equation 14, wherein R 23 is lower alkyl, such as isopropyl. Equation 14 30 31 32 33 N-silyl-protected pyrrole ££, where R 23 is preferably an isopropyl group, is treated with an alkyllithium reagent such as n-butyllithium as described in Chem. Ber., Vol. 122, p. 169 (1989), and references cited therein. The resultant etalated species is treated with sulfur dioxide to afford sulfinate salt £1 which is then converted to sulfonamide £2. by any of a number of known methods, for example, treatment with N-chlorosuccinimide followed by amination with an appropriate primary amine as disclosed in U.S. Patent 4,481,029. The N-silyl group is then removed, most conveniently with an alkali fluoride or quaternary ammonium fluoride salt, to afford ρyrrole-3-sulfonamide ££ (equivalent to Formula 2 wherein R 1 -H, W-CH) . Additional derivatives of Formula 2 where R- is other than H, and W is CR 13 (where R 13 ≠H) may be prepared by analogous methods. In sulfonamides of Formula 4. in the pyrrole and pyrazole series, where R 1 and/or R 2 is chloro or bromo, it may be more practical to introduce the halogens via a halogenation reaction on the corresponding unsubstituted bicyclic sulfonamides. Pyrrole-2-sulfonamides where L is L-17 are available from precursors £5 as depicted in Equation 15, wherein R 19 , R 20 , R 23 , X 5 , and R 7 are as defined above, and R 9 is t-butyl.

Subsequent conversion of £2 to ££ where X 5 is a leaving group such as a sulfonate ester, followed by metalation analogous to that described in Equation 12, affords the bicyclic pyrrole-2-sulfonamides ££. In the case where R 7 is an ester functionality, esters in which R 9 is other than t-butyl may be prepared from the t-butyl ester by heating £2. in the appropriate alcohol solvent with acid catalysis to effect a transesterification to sulfonamides ££ wherein R 9 is Cι-C 4 alkyl.

The nitro group of ______ is reduced to aniline ___{_. with any of a number of reducing agents such as iron powder in acetic acid, hydrogen and palladium metal catalyst, and the like.

Vol. 16, Agriculturally suitable salts of compounds of Formula I are also useful herbicides and can be prepared in a number of ways known to the art. For example, metal salts can be made by contacting compounds of Formula I with a solution of an alkali or alkaline earth metal salt having a sufficiently basic anion (e.g., hydroxide, alkoxide, carbonate or hydroxide) . Quaternary amine salts can be made by similar techniques. Salts of compounds of Formula I can also be prepared by exchange of one cation for another. Cationic exchange can be effected by direct contact of an aqueous solution of a salt of a compound of Formula I (e.g., alkali or quaternary amine salt) with a solution containing the cation to be exchanged. This method is most effective when the desired salt containing the exchanged cation is insoluble in water and can be separated by filtration. Exchange may also be effected by passing an aqueous solution of a salt of a compound of Formula I (e.g., an alkali metal or quaternary amine salt) through a column packed with a cation exchange resin containing the cation to be exchanged for that of the original salt and the desired product is eluted from the column. This method is particularly useful when the desired salt is water-soluble, e.g., a potassium, sodium or calcium salt. Acid addition salts, useful in this invention, can be obtained by reacting a compound of Formula I with a suitable acid, e.g., p-toluenesulfonic acid, trichloroacetic acid or the like. The preparation of the compounds of this invention is further illustrated by the following specific examples. Temperatures are reported in degrees Celsius; abbreviations for nuclear magnetic resonance (NMR) are: s - singlet, d - doublet, t ■ triplet, m - multiplet, and peak positions are reported as parts per million downfield from internal tetramethylsilane. Infrared (IR) peak positions are given in reciprocal centimeters (cm- ) and sh denotes a shoulder. Example 1 N-(l.l-Dimethylethyl -l-rtris(l-methylethyl)sii y n- lH-pyrrole-3-sulfonamide A solution of 4.55 g (0.0151 mol) of 3-bromo-N-triisopropylsilylpyrrole in 100 mL' anhydrous tetrahydrofuran (THF) under nitrogen atmosphere was cooled to -60°C then treated with 10.4 mL of 1.6 M butyllithium in hexanes (0.0166 mol) dropwise at such a rate as to keep the temperature below -60°C. After ca. 30 minutes at this temperature, liquified sulfur dioxide was added (3.9 mL, 0.090 mol). The brown solution was then warmed to room temperature, and the THF was removed under reduced pressure. The resulting light brown solid was dissolved in 100 mL acetic acid and then treated with 2.0 g (0.015 mol) N-chlorosuccinimide with cooling to keep the temperature less than 25°C. After 2 hours, the acetic acid was evaporated under reduced pressure and the residue taken up in ethyl acetate.

They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 0.1% to 99% by weight of active ingredient(s) and at least one of (a) about 0.1% to 20% surfactant(s) and (b) about 1% to 99.9% solid or liquid inert diluent(s). More specifically, they will contain these ingredients in the following approximate proportions: Weight Percent* Active * Active ingredient plus at least one of a Surfactant or a Diluent equals 100 weight percent. Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are some¬ times desirable, and are achieved by incorporation into the formulation or by tank mixing. Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, New Jersey, but other solids, either mined or manufac¬ tured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide," 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0°C. "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ridgewood, New Jersey, as well as Sisely and Wood, "Encyclopedia of Surface Active Agents", Chemical Publishing Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc. The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example. Littler, U.S. Patent 3,060,084). Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See J. E. Browning, "Agglomeration", Chemical Engineering.
