     All of the compounds of Formula XXX are useful as anti-asthmatic agents or antiinflammatory agents as described in detail below except for compounds of Formula XXX wherein: X is cis CH═CH, Y is (CH 2 ) n , n is 3, Z is COOM 1 , M 1  is H, w is 1 and R 1  is 4-methoxyphenyl. Although these excluded compounds do not possess anti-asthmatic properties said compounds are useful as intermediates in the preparation of compounds of Formula XXX which are useful as anti-asthmatics or antiinflammatories which will be apparent from the detailed description and specific examples set forth herein below. 
     The carbon atom content of various hydrocarbon-containing moieties is indicated by a prefix designating the minimum and maximum number of carbon atoms in the moiety, i.e., the prefix (C i  -C j ) indicates a moiety of the integer &#34;i&#34; to the integer &#34;j&#34; carbon atoms, inclusive. Thus, for example, (C 1  -C 3 ) alkyl refers to alkyl of one to three carbon atoms, inclusive, or methyl, ethyl, propyl, and isopropyl. 
     Examples of alkyl of one to nine carbon atoms, inclusive, are methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, and nonyl, and isomeric forms thereof. 
     Pharmaceutically acceptable salts of the compounds of Formula XXX wherein M 1  is hydrogen are those formed with any suitable inorganic or organic bases, such as those of alkali metals, for example, sodium and potasium; alkaline earth metals, for example, calcium and magnesium; light metals of Group IIIA, for example, aluminum, and organic amines. Such salts are pharmacologically acceptable amine salts, i.e., amines which are accepted by mammals in an essentially non-toxic manner when administered to mammals in conjunction with the acid moiety of the invention. Illustrative of the amines are those derived from primary, secondary, or tertiary amines. Examples of suitable amines are methylamine, dimethylamine, triethylamine, ethylamine, dibutylamine, triisopropylamine, N-methylhexylamine, decylamine, dodecylamine, allylamine, crotylamine, cyclopentylamine, dicyclohexylamine, benzylamine, dibenzylamine, α-phenylethylamine, β-phenylethylamine, ethylenediamine, diethylenetriamine, adamantylamines, and like aliphatic, cycloaliphatic, and araliphatic amines containing up to and including about 18 carbon atoms as well as heterocyclic amines, e.g., piperidine, morpholine, pyrrolidine, piperazine, and lower-alkyl derivatives thereof, e.g., 1-methylpiperidine, 4-ethylmorpholine, 1-isopropylpyrrolidine, 2-methylpyrrolidine, 1,4-dimethylpiperazine, 2-methylpiperidine, and the like, as well as amines containing water-solubilizing or hydrophilic groups, e.g., mono-, di-, triethanolamine, ethyldiethanolamine, N-butylethanolamine, 2-amino- 1-butanol, 2-amino-1-ethyl-1,3-propanediol, 2-amino-2-hydroxymethyl-1,3-propanediol (THAM), 2-amino-2-methyl-1-propanol, tri(hydroxymethyl)aminoethane, N-phenylethanolamine, N-(p-tert-amylphenyl)diethanolamine, galactamine, N-methylglucamine, N-methylglucosamine, ephedrin, phenylephrine, epinephrine, or procaine. 
     The compounds of the present invention will be named herein using the Chemical Abstracts numbering system (see &#34;Naming and Indexing of Chemical Substances for Chemical Abstracts during the Ninth Collective Period (1972-1976),&#34; a reprint of section IV from the Volume 76 Index Guide). 
     The process of the present invention is more completely understood by reference to the charts below. In these charts, the variables are as defined above. Formula IX represents the geometrical isomer mixture. Formulae X and XI represent the pure geometric isomers in the cis configuration and trans configuration, respectively. 
     The compounds of this invention are described by the procedure set forth hereinbelow. Chart A herein describes the method by which novel compounds of this invention are prepared. Charts B and C herein describe methods by which additional novel compounds of this invention are prepared from the final compound in Chart A. Chart D herein describes the method by which intermediates in Chart A may be prepared. Chart E herein describes the method by which additional novel compounds of this invention are prepared from intermediates in Chart A. 
     With respect to Chart A, condensation of the diazonium salt of the appropriate aromatic amine of formula I with ethyl acetoacetate provides the hydrazone of formula II. Bromination of the formula II hydrazone, as described in M. Nagakura et al., J. Med. Chem. 22:48 (1979), provides the bromo-substituted hydrazone of formula III. Dipolar cycloaddition of the nitrilamine derived from the formula III bromo-substituted hydrazone with the appropriate amine (e.g., morpholino-cyclopentene or pyrrolidino-cyclopentene; morpholino-cyclohexene or pyrrolidino-cyclohexene) provides the cyclopentapyrazole or tetrahydroindazole of formula IV where X is morpholino or pyrrolidino. Elimination of the cycloaliphatic amine moiety with aqueous acid or polyphosphoric acid in acetic acid provides the 3-carboethoxy cyclopentapyrazole or tetrahydroindazole of formula V. Precedents of the above reactions are described in M. Nagakura et al., J. Med. Chem. 22:48 (1979); R. Fusco et al., Gazz. Chim. Ital., 91:1233 (1961); R. Huisgen et al., Ang. Chem. 91:347 (1979); R. Huisgen et al., Tetrahedron Letters 32:2987 (1979). Other references include: German 2828-529; R. Scuri, Boll. Chim. Farm. 674 (1970); S. I. Nagai et al., Chem. Pharm. Bull. 27:1764 (1979); G. G. Massaroli et al., Boll. Chim. Farm. 107:613 (1968). 
     Reduction of the carboethoxy group of the formula V cyclopentapyrazole or tetrahydroindazole (e.g., when R 1  is phenyl, dichlorophenyl, difluorophenyl, trifluoromethylphenyl or methylphenyl) with lithium tetrahydroaluminate provides the carbinol of formula VII. 
     Alternatively, in the cases of aryl functionalities sensitive to lithium tetrahydroaluminate, the carboethoxy group of the formula V cyclopentapyrazole or tetrahydroindazole (e.g., when R 1  is nitrophenyl, bromophenyl, or chlorophenyl) is hydrolyzed to the acid of formula VI, and the carbinol of formula VII is obtained by treatment with diborane. 
     Oxidation of the carbinols of formula VII are conveniently performed with activated manganese dioxide in toluene under azeotropic distillation conditions to provide the carboxaldehydes of formula VIII. The carboxaldehydes of formula VIII are homologated to the geometrical isomer mixture of formula IX (e.g., when n is 1 to 5 and M 1  is --H) by Wittig reactions. The pure geometrical isomers of formula IX, i.e., formulae X and XI, are conveniently separated on silica gel as the corresponding methyl esters (e.g., when n is 1 to 5 and M 1  is --CH 3 ). These methyl esters are obtained by diazomethane esterification. Fisher-type esterifications (alcoholic hydrochloric acid or sulfuric acid) are applicable in larger scale operations. The pure geometrical isomers of formula IX, i.e., formulae X and XI, (e.g., when n is 1 to 5 and M 1  is --H) are regenerated by saponification in alcoholic sodium hydroxide solutions. 
     Condensation of the aldehydes of formula VIII with malonic acid provides the propenoic acids of formula XI (when n is 0 and M 1  is --H). 
     The carboxaldehydes of formula VIII are converted to the compound of formula XVII by Wittig reactions. The compound of formula XIII is obtained by reduction of the compound of formula XVII. Reduction of the vinyl group of formula XVII is conveniently performed by catalytic hydrogenation (e.g., palladium on carbon, platinum oxide catalysis) when substituents insensitive to reduction or hydrogenolysis are present (e.g., when R 1  is tolyl, trifluoromethylphenyl, fluorophenyl, or acetamidophenyl). Diborane reduction achieves the same objective when reduction-sensitive substituents are present (e.g., when R 1  is chlorophenyl, bromophenyl, or nitrophenyl). Geometrical isomers are separated on silica gel or more easily on silica gel pretreated with silver nitrate. 
     Further, the carboxaldehyde of formula VIII is converted to the compound of formula XXVII by reaction with alcohol (e.g., R 13  OH or R 12  OH) or glycol (e.g., ##STR6## in the presence of acid (e.g., toluenesulfonic acid) neat in the case of lower-alkyl alcohols and with a solvent (e.g., toluene) in the case of glycols. 
     With respect to Chart B, reduction of the vinyl group of the formula IX compound to the formula XII compound is conveniently performed by catalytic hydrogenation (e.g., palladium on carbon, platinum oxide catalysis) when substituents insensitive to reduction or hydrogenolysis are present (e.g., when R 1  is tolyl, trifluoromethylphenyl, fluorophenyl, or acetamidophenyl). Diborane reduction achieves the same objective when reduction-sensitive substituents are present (e.g., when R 1  is chlorophenyl, bromophenyl, or nitrophenyl). The catalytic hydrogenations are easily performed on either the esters of formula IX (e.g., when n is 1 to 5 and M 1  is --CH 3 ) or the acids of formula IX (e.g., when n is 1 to 5 and M 1  is --H). Diborane reduction of vinyl substituents is best conducted on the esters of formula IX. 
     The terminal carbinols of formula XIV (when n is 1 to 5) are obtained either by lithium tetrahydroaluminate reduction of the esters or acids of formula XII (e.g., when n is 1 to 5 and M 1  is --CH 3  or --H) or by extending the reaction time with diborane. 
     With respect to both Charts B and C, the carboxylic acids of formulae XII and IX or pure isomers of formulae X and XI (e.g., when n is 1 to 5 and M 1  is --H) are activated for conversions to esters of formulae XII, IX, X and XI, respectively, (e.g., when n is 1 to 5 and M 1  is --(C 1  -C 4 ) alkyl, phenyl or substituted phenyl) and amides of formula XXV and XVI (e.g., when n is 1 to 5 and R 5  and R 6  are as defined above) by procedures known in the art. Thus, the acid chlorides are synthesized by the procedure of J. Cason, Org. Syn., Coll. Vol. 3:169 (1955). For mixed anhydrides, the acid is reacted with, e.g., isobutylchloroformate/triethylamine in chlorocarbon solvents. Other methods include those of Y. Kita, Tetrahedron Letters 25:6027 (1984); K. Saigo, Bull. Chem. Soc. Japan 50:1863 (1977); and F. H. Stodola, J. Org. Chem. 29:2490 (1964). 
     The activated acids are then reacted with the appropriate alcohol (e.g., M 1  OH) or amine (e.g., HNR 5  R 6 ) to provide the esters or amides, respectively. The reaction of acid chlorides with alcohols or amines may be conducted in chlorocarbon solvents, tetrahydrofuran, or acetonitriles with an acid scavenger present (e.g., pyridine, triethylamine). The reaction of mixed anhydrides are conducted with or without solvent, the alcohol or amine, as noted above, being used as the solvent when convenient or the above listed solvent being used as required. 
     Further, with respect to Chart C, diphenylamine borane, according to the method of R. Contreras et al., Synthesis 1027 (1982), or lithium tetrahydride aluminate reduce the terminal acids or esters of formula IX (e.g., when M 1  is --H or --CH 3 ), respectively, to the unsaturated carbinols of formula XV. 
     The epoxidation reaction of the compound of formula IX (e.g., when n is 1 to 5 and M 1  is --H or --CH 3 ) to the formula XXVI expoxide is carried out conveniently in methylene chloride with m-chloroperoxybenzoic acid for from four to twenty-four hours. The vinyl group yields an expoxy group of like cis or trans configuration. An example of such a reaction is presented in J. Fried et al., Tetrahedron Letters 849 (1965). 
     With respect to Chart D, the cyclohexanone glyoxylate of formula XIX, K. V. Auwers et al., Ann. 57:469 (1929) is condensed with a hydrazine derivative of formula XVIII (e.g., when R 1  is 4-alkoxyphenyl, 4-thioalkylphenyl, benzyl or substituted benzyl) by literature procedures, e.g., L. G. Tensmeyer and C. Ainsworth, J. Org. Chem. 31:1878 (1966). The resulting isomeric cyclopentapyrazoles or tetrahydroindazoles of formula V (e.g., when R 1  is 4-alkoxyphenyl, benzyl or substituted benzyl) are separated by chromatography and the side chain of the formula V compound is elaborated by procedures described for Chart A. 
     With respect to Chart E, heteroatom chains of the formula XX compound (e.g., when m is 1 or 2 and M 1  is --CH 3 , --CH 2  CH 3  or --H) are elaborated by generation of the alkoxide from the formula VII compound and condensation with a halo ester (e.g., ethyl bromoacetate). The halomethylcyclopentapyrazole or halomethyltetrahydroindazole of formula XXI is prepared from the formula VII compound and thionyl chloride (or, alternatively, methane sulfonyl chloride). The thia side chains of the formula XXII compound, (e.g., when m is 1 or 2 and M 1  is --H, --CH 3  or --CH 2  CH 3 ) are produced from the halomethylcyclopentapyrazole or halomethyltetrahydroindazole of formula XXI by condensation with a mercapto ester (e.g., methyl thioglycollate). 
     The terminal carbinols of formulae XXIII and XXIV are obtained either by lithium tetrahydroaluminate reduction of the esters or acids of formulae XX and XXII or by extending the reaction time of diborane reduction. 
     The compounds of Formula XXX, except for the following compounds: (1) X is cis --CH═CH--, Y is --(CH 2 ) n  --, n is 3, Z is --COOM 1 , M 1  is --H, R 1  is 4-methoxyphenyl and w is 1; (2) X-Y-Z taken together are --CH 2  OH, R 1  is 3,4-dichlorophenyl and w is 1; (3) X-Y-Z taken together are --CH 2  OH, R 1  is 4-fluorophenyl and w is 2; and (4) X is trans --CH═CH--, Y is --(CH 2 ) n  --, n is 2, Z is --COOM 1 , M 1  is --CH 3 , R 1  is 3,4-dichlorophenyl and w is 1; are useful for the prophylactic or therapeutic treatment of allergy of a reagin or non-reagin mediated nature in humans and animals, particularly mammals. These compounds are particularly useful in treating asthma, but any allergy wherein slow reacting substance of anaphylaxis (SRSA) is thought to be involved as a pharmacological mediator of anaphylaxis can be treated. For example, the compounds can be used for treatment of such conditions as allergic rhinitis, food allergy and urticaria as well as asthma. 
     An effective but essentially non-toxic quantity of these pharmaceutically useful compounds are employed in treatment. The dosage of the compound used in treatment depends on the particular use, frequency of administration and the age or condition of the recipient. The compounds can be administered intravenously, intramuscularly, topically, bucally, by aerosol, inhalation, or orally to man or other animals. The dosage is about 0.01 to 10 μg/kg per minute by intravenous infusion, i.e., an i.v. drip; 0.5 to 20 mg by intravenous bolus administration one to four times per day; about 2 to 50 mg orally in single doses; 200-800 mg total daily dosage given in divided doses two or three times a day. 
     The pharmaceutically useful compounds are formulated into compositions for administration. The compositions of the present invention are presented for administration to humans and animals in unit dosage forms, such as tablets, capsules, pills, powders, granules, sterile parenteral solutions or suspensions, eye drops, oral solutions or suspensions, oil in water and water in oil emulsions containing suitable quantities of the compound, suppositories, aerosols and in fluid suspensions or solutions. 
     For oral administration, either solid or fluid unit dosage forms can be prepared. For preparing solid compositions such as tablets, the pharmaceutically useful compound of Formula XXX is mixed with conventional ingredients such as talc, magnesium stearate, dicalcium phosphate, magnesium aluminum silicate, calcium sulfate, starch, lactose, acacia, methylcellulose, and functionally similar materials as pharmaceutical diluents or carriers. Capsules are prepared by mixing the compound with an inert pharmaceutical diluent and filling the mixture into a hard gelatin capsule of appropriate size. Soft gelatin capsules are prepared by machine encapsulation of a slurry of the compound with an acceptable vegetable oil, light liquid petroleum or other inert oil. 
     Fluid unit dosage forms for oral administration such as syrups, elixirs, and suspensions can be prepared. The forms can be dissolved in an aqueous vehicle together with sugar, aromatic flavoring agents and preservatives to form a syrup. An elixir is prepared by using a hydroalcoholic (ethanol) vehicle with suitable sweeteners such as sugar and saccharin, together with an aromatic flavoring agent. 
     Suspensions can be prepared with an aqueous vehicle with the aid of a suspending agent such as acacia, tragacanth, methylcellulose and the like. 
     For parenteral administration, fluid unit dosage forms are prepared utilizing the compound and a sterile vehicle, water being preferred. The pharmaceutically useful compound described herein, depending on the vehicle and concentration used, can be either suspended or dissolved in the vehicle. In preparing solutions the compound can be dissolved in water for injection and filter sterilzed before filling into a suitable vial or ampoule and sealing. Advantageously, adjuvants such as a local anesthetic, preservative and buffering agents can be dissolved in the vehicle. To enhance the stability, the composition can be frozen after filling into the vial and the water removed under vacuum. The dry lyophilized powder is then sealed in the vial and an accompanying vial of water for injection is supplied to reconstitute the liquid prior to use. Parenteral suspensions can be prepared in substantially the same manner except that the compound is suspended in the vehicle instead of being dissolved and sterilization cannot be accomplished by filtration. These compounds can be sterilized by exposure to ethylene oxide or an equivalent gas before suspending in the sterile vehicle. Advantageously, a surfactant or wetting agent is included in the composition to facilitate uniform distribution of the compound. 
     Compositions for inhalation useful in practicing the present invention are of three basic types: (1) a powder mixture preferably micropulverized with particle size, preferably from about 2 to 5 microns; (2) an aqueous solution to be sprayed with a nebulizer; (3) an aerosol with volatile propellant in a pressurized container. 
     The powders are quite simply prepared by mixing a suitable pharmaceutically useful compound of Formula XXX with a solid base which is compatible with lung tissue, preferably lactose. The powders are packaged in a device adapted to emit a measured amount of powder when inhaled through the mouth. 
     Aqueous solutions are prepared by dissolving the appropriate compound of the Formula XXX in water and adding salt to provide an isotonic solution and buffering to a pH compatible with inhalation. The solutions are dispersed in a spray device or nebulizer and sprayed into the mouth while inhaling. 
     Aerosols are prepared by dissolving an appropriate pharmaceutically useful compound of Formula XXX in water or ethanol and mixing with a volatile propellant and placing in a pressurized container having a metering valve to release a predetermined amount of material. 
     The liquefied propellent employed is one which has a boiling point below 65° F. at atmospheric pressure. For use in compositions intended to produce aerosols for medicinal use, the liquefied propellant should be non-toxic. Among the suitable liquefied propellants which may be employed are the lower alkanes containing up to 5 carbon atoms, such as butane and pentane, or a lower alkyl chloride, such as methyl, ethyl or propyl chlorides. Further suitable liquefied propellants are the fluorinated and fluorochlorinated lower alkanes such as are sold under the trademarks &#34;Freon&#34; and &#34;Genetron&#34;. Mixtures of the above-mentioned propellants may suitably be employed. Examples of these propellants are dichlorodifluoromethane (&#34;Freon 12&#34;), dichlorotetrafluoroethane (&#34;Freon 114&#34;), trichloromonofluoromethane (&#34;Freon 11&#34;), dichloromonofluoromethane (&#34;Freon 21&#34;), monochlorodifluoromethane (&#34;Freon 22&#34;), trichlorotrifluoroethane (&#34;Freon 113&#34;), difluoroethane (&#34;Genetron 142-A&#34;) and monochlorotrifluoromethane (&#34;Freon 13&#34;).
