Description: Field of the Invention This invention relates to the use of certain imidazoline compounds and analogues thereof for the treatment of diabetes, diabetic complications, metabolic disorders, or related diseases where impaired glucose disposal is present. Background of the Invention It is generally accepted that the control of blood glucose levels for the treatment of patients diagnosed with type II diabetes will have a beneficial effect. Established oral therapies for treating type II diabetes either improve insulin action or cause enhanced insulin secretion. The agents currently approved as therapies for type II diabetes patients that cause an enhanced insulin secretion contain a sulphonlyurea moiety. These compounds act by depolarising the beta cell by modulating closure of the K-ATP channel. Additional compounds that act at the K-ATP channel are under consideration for treatment of type II diabetes and that are not sulphonylurea compounds and have a fast onset of activity and short duration of action such as (-)-N-(trans-4-isopropylcyclohexanecarbonyl)-D-phenylalanine (A-4166) (Brit. J. Pharm. 1997, 120, 137-145). All agents that function at the molecular level by modulating the K-ATP channel have the potential for inducing hypoglycemia. Hypoglycemia is the major cause of adverse reactions in patients receiving sulphonylurea therapy and the prevalence of hypoglycemic episodes can be as high as 20% of patients. WO 92/06972 relates to the use of certain 2-(N substituted indol-2-yl) imidazole, 2-(N-substituted indol-Z-yl)-3, 4, 5, 6-tetrahydro pyr imidine and 2-(N-substituted indol-2-yl)-4, 5, 6, 7-terra hydro-1H-1, 3-diazepine compounds in the treatment of diabetes. Compounds that potentiate insulin secretion under high glucose conditions and have little or no effect at low blood glucose levels would offer a distinct advantage in the treatment of type II diabetes. Summary of the Invention Compounds for use according to the present invention potentiate the secretion of insulin from beta cells under high glucose conditions and have minimal effect under low glucose conditions. The compounds are also operable in additional disease states where impaired glucose disposal is present. For example, these include cardiovascular disease where above normal glucose levels are present or initial insulin resistance has occurred. The compounds can also be used to treat post operative insulin resistance induced by anaesthesia. The present invention provides use of compounds of the following Formula (I) in the treatment of diabetes, especially Type II diabetes, diabetic complications, and metabolic disorders or related diseases in particular where impaired glucose disposal is present. wherein X is -O-, -S-, or -NR 5 -; R 5 is hydrogen or C 1-8 alkyl; R 1 , R 1' , R 2 , and R 3 are independently hydrogen or C 1-8 alkyl; R 1 and R 2 optionally together form a bond and R 1' and R 3 are independently hydrogen or C 1-8 alkyl; R 1 and R 2 optionally combine together with the carbon atoms to which they are attached form a C 3-7 carbocyclic ring and R 1' and R 3 are independently hydrogen or C 1-8 alkyl; R 1 and R 1' together with the carbon atom to which they are attached optionally combine to form a C 3-7 spirocarbocyclic ring and R 2 and R 3 are independently hydrogen or C 1-8 alkyl; R 2 and R 3 together with the carbon atom to which they are attached optionally combine to form a C 3-7 spirocarbocyclic ring and R 1 and R 1' are independently hydrogen or C 1-8 alkyl; n is 0, 1, or 2; R 4 is Y is -O-, -S-, or -NR 8 -; Y' is -O- or -S-; R 6 and R 7 are independently hydrogen, C 1-8 alkyl, C 3-7 cycloalkyl, C 1-8 alkoxy, C 1-8 alkylthio, halo C 1-8 alkylthio, C 1-8 alkylsulfinyl, C 1-8 alkylsulfonyl, C 3-7 cycloalkoxy, aryl-C 1-8 alkoxy, halo, halo-C 1-8 alkyl, halo- C 1-8 alkoxy, nitro, -NR 10 R 11 , -CONR 10 R 11 , aryl C 1-8 alkyl, optionally substituted heterocyclyl, optionally substituted phenyl, optionally substituted naphthyl, optionally halo substituted acylamino, cyano, hydroxy, COR 12 , halo C 1-8 alkylsulfinyl, or halo C 1-8 alkylsulfonyl, or alkoxyalkyl of the formula CH 3 (CH 2 ) p -O-(CH 2 ) q -O-; where p is 0, 1, 2, 3, or 4; and q is 1, 2, 3, 4, or 5; R 12 is C 1-8 alkyl or optionally substituted phenyl; R 8 is hydrogen, C 1-8 alkyl, halo-C 1-8 alkyl, optionally substituted phenyl, optionally substituted heterocyclyl, COO C 1-8 alkyl, optionally substituted COaryl, COC 1-8 alkyl, SO 2 C 1-8 alkyl, optionally substituted SO 2 aryl, optionally substituted phenyl-C 1-8 alkyl, CH 3 (CH 2 ) p -O-(CH 2 ) q -O-; R 9 is hydrogen, halo, C 1-8 alkyl, halo C 1-8 alkyl, C 1-8 alkylthio, halo C 1-8 alkylthio, C 3-7 cycloalkylthio, optionally substituted arylthio or heteroarylthio, C 1-8 alkoxy, C 3-7 cycloalkoxy, optionally substituted aryloxy , optionally substituted heteroaryloxy, or optionally substituted aryl or heteroaryl, C 3-7 cycloalkyl, halo C 3-7 cycloalkyl, C 3-7 cycloalkenyl, cyano, COOR 10 ,CONR 10 R 11 or NR 10 R 11 , C 2-6 alkenyl, optionally substituted heterocyclyl, optionally substituted aryl C 1-8 alkyl, optionally substituted heteroaryl C C 1-8 alkyl in which the alkyl group can be substituted by hydroxy, or C 1-8 alkyl substituted by hydroxy, R 10 and R 11 are independently hydrogen, C 1-8 alkyl, optionally substituted aryl C 1-8 alkyl, optionally substituted phenyl, or R 10 and R 11 together with the nitrogen atom to which they are attached may combine to form a ring with up to six carbon atoms which optionally may be substituted with up to two C 1-8 alkyl groups or one carbon atom may be replaced by oxygen or sulfur; R 14 and R 16 are independently hydrogen, halo, C 1-8 alkyl, C 3-7 cycloalkyl, C 3-7 cycloalkoxy, C 3-7 cycloalkylC 1-8 alkoxy, halo-C 1-8 alkyl, halo-C 1-8 alkoxy, C 1-8 alkoxy, carbo(C 1-8 )alkoxy, optionally substituted aryl, or optionally substituted heteroaryl; R 15 and R 17 are independently hydrogen, halo, C 1-8 alkoxy, C 3-7 -cycloalkyl, C 3-7 cycloalkylC 1-8 alkoxy, C 1-8 alkyl, C 3-7 cycloalkoxy, hydroxy, halo C 1-8 alkoxy, carbo(C 1-8 )alkoxy, optionally substituted phenyl, optionally substituted phenyl-C 1-8 alkyl, optionally substituted phenyloxy, optionally substituted phenyl-C 1-8 alkoxy, (tetrahydropyran-2-yl)methoxy, C 1-8 alkyl-S(O) m -, optionally substituted aryl-C 1-8 alkyl-S(O) m' -, CH 3 (CH 2 ) p -Z 1 -(CH 2 ) q -Z 2 -, or Z 3 -(CH 2 )q'-Z 2 -; where: m is 0, 1 or 2; m' is 0, 1, or 2; q' is 0, 1, 2, 3, 4, or 5; Z 1 and Z 2 are independently a bond, O, S, SO, SO 2 , sulphoximino, or NR 10 ; and Z 3 is hydroxy, NR 10 R 11 , or SH; provided that when R 1 , R 1' , R 2 and R 3 are all hydrogen; n is 0; R 4 is naphthyl; and R 14 , R 15 and R 16 , or R 15 , R 16 and R 17 are all hydrogen, then R 17 or R 14 , respectively, is other than halo, methoxy, or C 1-6 alkyl; and pharmaceutically acceptable salts and esters thereof.

GENERAL SCHEME FOR THE SYNTHESIS OF INDOLYL-IMIDAZOLINES Compounds of formula I wherein X is NH; R 1 , R 1' , R 2 , R 3 are hydrogen; n is 1 or 2; R 4 is and R 6 , R 7 , R 9 have the definitions given above can be prepared according to scheme L wherein R 4 and n are as defined herein for Formula I, and J is C 1-8 alkyl, aryl, or aryl C 1-8 alkyl. The transformation described in Scheme I is novel and is described in Scheme Ia. Cyclisation is induced by a silylating agent or a mixture of silylating agents, optionally in the presence of an soluble or insoluble base, e.g. triethyl amine or dimethylaminomethyl polystyrene and a solvent. Useful reagents are e.g. described in FLUKA Chemika , "Silylating Agents" (1995) ISBN 3-905617-08-0 and the literature cited therein. In a more prefered embodiment, these silylating agents are trimethyl silyl halogenides, TMS-X (e.g. trimethyl silyl chloride or trimethyl silyl iodide) or hexamethyl disilazane, HMDS or trimethyl silyl diethylamine, TMS-DEA or mixtures of them. In the most prefered embodiment the reactions are carried out either in methylene chloride with excess TMS-Cl or, more prefered, TMS-I in presence of triethyl amine or dimethylaminomethyl polystyrene at ambient temperature, or in neat HMDS or HMDS/TMS-Cl 100/1, without additional base and solvent at 50°C to reflux, preferably at 70°C to 90°C. In some cases, using TMS-X as cyclizing reagent, excessive reagent has to be added in several portions within a period of time (up to about a week) to ensure complete conversion. The process described herein is compatible to many functionalities present in an organic molecule, e.g. unprotected hydroxy, unprotected amino, olefinic double bond, cyano, nitro, aromatic halogen, amide and is sucessful in some cases, when conventional methods failed ( Chem. Pharm. Bull. 1980 , 28 , 1394-1402). The process described in Scheme Ia affords numerous advantages over similar methods known in the art. The transformation can be achieved in high yield and under mild conditions, whereas, methods known in the art require the use of extreme conditions or reagents Compounds of formula I wherein X is NH; R 1 , R 1' , R 2 , R 3 are hydrogen; n is 0; R 4 is and R 6 , R 7 , R 9 have the definitions given above can be prepared according to scheme II. J 1 is COR 2 or CO 2 R 2 and R 2 is C 1 -C 8 alkyl, aryl, or aryl C 1 -C 8 alkyl. The process described in Scheme II is novel The process describes the preparation of imidazolines of formula I in which X is NH and R4 is an indole nucleus. The process is affected by treating a compound of formula (IV) with a compound of formula (III) in the presence of a dehydration agent between room temperature and 140°C; followed by treatment with an alcohol or water between room temperature and the boiling point of the reaction mixturre. The preferred compounds of formula III are 1-acetyl-imidazoline-2-one or 1-(phenyloxycarbonyl)-imidazoline-2-one. The preferred dehydration agent is phosphorus oxychloride or thionylchloride. The preferred reagent for the deprotection of the N-substituted-imidazoline or the N-substituted-imidazole is ethanol or water. The indole nuclei of formulas (II and IV) utilized in Schemes I and II are known in the art and can be prepared as shown in the Schemes IIIa-IIIf below and as described, for example, in Bull. Soc. Chim. Fr .1969 (4), 1227-34, with the modifications shown, for Schemes IIIa-IIId, and J. Org. Chem .(1994) 59, 6372, with the modifications shown, for Scheme IIIf. Scheme IIIg, below, describes a method for the synthesis of 3-cyanoindoles and subsequent transformation to the corresponding imidazolines, which are substituted by an aryl or heteroaryl group in position 2 of the indole nucleus. Nitrobenzene derivatives react with acetonitrile derivatives which contain a leaving group L to give (2-nitrophenyl)acetonitriles. Reactions of this type are known , for example as reported by M. Makosza et al., Liebigs Ann. Chem. / Recl. 1997 , 1805. Typical leaving groups L are halogens, substituted or unsubstituted phenoxy groups, or substituted or unsubstituted phenylthio groups. A preferred value for L is 4-chlorophenoxy. The reaction can be carried out with strong bases, for example, NaOH or KOH, or with alkoxylates, for example, potassium tert.-butoxide in polar solvents such as DMF or DMSO. The resulting acetonitrile is alkylated with benzyl halides or heteroarylmethyl halides, preferably bromides or chlorides. This reaction requires a base typically used for such alkylation. A preferred method uses potassium carbonate and a phase transfer catalyst, for example a crown ether. The following cyclization to 3-cyano-1-hydroxyindoles may also be carried out with strong bases in polar solvents as described above. A preferred procedure uses sodium hydroxide in DMSO. The removal of the 1-hydroxy group can be achieved under conditions which are typically used for this purpose, for example catalytic hydrogenation, reduction with metals, or with phosphorus reagents such as trialkyl phosphites, for example as reported by R.M. Acheson, in "Advances in Heterocyclic Chemistry", Vol. 51 , p.129. In a preferred method the reduction is carried out by heating with trimethyl phosphite. The transformation of the cyano group to an imidazoline is achieved by heating with ethylenediamine. This reaction is achieved, in a preferred process, with ethylenediamine tosylate by heating of both reactants at temperatures > 300 °C. wherein R 9 is aryl or heteroaryl. Scheme IIIh describes a method for the synthesis of indol-3-yl acetates and propionates containing an aryl or heteroaryl group in the 2-position of the indole ring. Indol-3-yl acetates and propionates which are unsubstituted in position 2 are commercially available or may be prepared according to procedures known in the art, for example, in a similar manner as described in SchemeIIIb. The bromination in the 2-position of the indole nucleus may be achieved with bromination reagents and reaction conditions known in the art, for example bromine, NBS, TMS bromide /DMSO, or pyridinium bromide perbromide. A preferred method uses NBS in dichloromethane at 0 °C. 2-Bromoindoles are converted to 2-aryl or heteroaryl indoles by standard conditions known in the art for Suzuki coupling reactions using aryl or heteroaryl boronic acids employing a Pd catalyst, preferably Pd(PPh 3 ) 4 . wherein R 9 is aryl or heteroaryl, n is 1 or 2, and J is C 1-4 alkyl. Compounds of Formula I, wherein X is NH; R 1 , R 1' , R 2 , and R 3 are hydrogen; n is 0; R 4 is and R 14 , R 15 , R 16 , and R 17 have the definitions given above can be prepared by methods known in the art or as described herein. A skilled artisan would appreciate that the compounds of Formula I could be prepared from the appropriate halo and hydroxy substituted naphthalenes. Such syntheses are illustrated in Schemes IV and V, below. wherein R 14' , R 15' , and R 17' are R 14 , R 15 , and R 17 , respectively, protected derivatives thereof, or precursor moieties thereto, and R 16' is optionally substituted aryl, or optionally substituted heteroaryl. wherein R 15' , R 16" and R 17' are R 15 , R 16 , and R 17 , respectively, protected derivatives thereof, or precursor moieties thereto, and R 14" is optionally substituted aryl, or optionally substituted heteroaryl. Scheme Via illustrates the introduction of the imidazoline group into the 3-position of the benzothiophene (Y = S) or the benzofuran nucleus (Y = O). The unsubstituted bicyclic heterocycle reacts with chloroformates, preferably with ethyl chloroformate to give the corresponding 3-carboxylates. The reaction is catalyzed by Lewis acids, for example, Al(III) chloride, Sn(IV) chloride, Ti(IV) chloride, or boron halides in halogenated hydrocarbons or in carbon disulfide. It should be noted that when carbon disulfide is used, intermediate dithioesters are formed as shown in Scheme VIa. A preferred method uses Al(III) chloride in carbon disulfide at room temperature. The transformation of the carboxylate or dithiocarboxylate to the imidazoline is achieved by reaction with ethylenediamine, preferably by heating in a solvent such as ethanol. This reaction is catalyzed by traces of carbon disulfide. Benzofurans (Y = O) or benzothiophenes (Y = S) with an optionally substituted aryl or optionally substituted heteroaryl group in the 2-position may be prepared as illustrated in Scheme VIb. The unsubstituted heterocycles are prepared by methods known in the art, preferably by heating of (2,2-dialkoxy)ethoxybenzenes or (2,2-dialkoxy)ethylthiobenzenes, respectively, in chlorobenzene with polyphosphoric acid. These intermediates are converted to the corresponding benzofuran-2-yl or benzothiophen-2-yl boronic acids using standard conditions known in the art which use metallation with butyl lithium and trapping of the carbanions with esters of boronic acid like triisopropyl borate followed by an acid work-up procedure. The following aryl coupling reaction is carried out as described above for Scheme IIIh. preferably using a Suzuki coupling method, which preferably is carried out with aryl or heteroaryl bromides or iodides. In another procedure, 2-bromobenzofurans or 2-bromobenzothiophenes are prepared using standard bromination reagents known in the art, for example NBS. In a preferred method, the heterocycles are lithiated with butyl lithium followed by trapping of the carbanions with bromine. The 2-bromoheterocycles are converted to 2-aryl or 2-heteroaryl derivatives in aryl coupling reactions with optionally substituted aryl or optionally substituted heteroaryl boronic acids. wherein R 9' is optionally substituted aryl or optionally substituted heteroaryl. Another route to benzofurans or benzothiophenes which are substituted in the 2-position by an optionally substituted aryl or optionally substituted heteroaryl group is illustrated in Scheme VIc. Phenols or thiophenols are reacted with arylacyl bromides or heteroarylacyl bromides to give the corresponding aryl- or heteroaryloxymethyl or aryl- or heteroarylthiomethylketones, respectively. The reaction is carried out in the presence of a base, for example potassium carbonate. These intermediates are heated under acidic conditions to give the corresponding bicyclic nuclei. A preferred method is heating in polyphosphoric acid (PPA). wherein R 9' is optionally substituted aryl or optionally substituted heteroaryl. Scheme VId describes a method for preparation of 2-methylbenzofurans or 2-methylbenzothiophenes. In the first step phenols or thiophenols, respectively, are alkylated with allyl halides which contain another leaving group L. A preferred group L is another halogen, and in a preferred method the alkylation is carried out by heating with 2,3-dichloropropene in acetone in the presence of a base, for example potassium carbonate. A preferred method for cyclization to form the heterocyclic rings is heating of the intermediate allylether or allythioether in N,N-diethylaniline. This reaction may or may not require an additional step for ring closure of the intermediate product derived from a Claisen rearrangement, for example by heating with hydrochloric acid. A particular method for the synthesis of benzofurans or benzothiophenes containing a 2-substituted ethyl group in position 2 of the nucleus is described in Scheme Vie. 2-Methylbenzofurans or 2-methylbenzothiophenes are brominated at the methyl group to give 2-bromomethyl derivatives by standard conditions known in the art used for benzylic brominations, preferably with NBS. These are converted to phosphonium salts by heating with phosphines, preferably by heating with triphenylphosphine to triphenylphosphonium bromides which react with aldehydes under standard conditions known in the art for Wittig reactions to give 2-vinylbenzofurans or 2-vinylbenzothiophenes. The corresponding ethyl derivatives are prepared by hydrogenation of the vinyl compounds. A preferred method uses borohydride / Ni(II) acetate, particularly borohydride which is fixed on an exchange resin. Such resins are familiar and readily commercially available from vendors known to the artisan, see for example, Bunin, B.A. (1998) The Combinatorial Index. Academic Press, San Diego.
