Den foreliggende opfindelse angår en analogi fremgangsmåde til fremstilling ad hidtil ukendte, terapeutisk aktive l-oxo-2,3-hydrocarbylen-5-indanyloxy-eddikesyrer med den i kravets indledning angivne almene formel eller ugiftige, farmaceutisk acceptable salte deraf.
Farmakologiske studier har vist, at de omhandlede forbindelser er effektive diuretiske og saluretiske midler, der kan benyttes til behandling af tilstande, som ledsager tilbageholdelse af elektrolytter og væsker. Desuden er forbindelserne uricosuretiske, og de kan opretholde urinsyrekoncentrationen i legemet på samme niveau som forud for behandling eller i visse tilfælde endog formindske urinsyrekoncentrationen.
Anvendelsen af de omhandlede forbindelser medfører væsentlige fordele frem for hidtil kendte diuretica og salure-tica, der ved indgift kan have en tilbøjelighed til at inducere hyperuricemia, hvorved der kan udfældes urinsyre eller natriumurat eller begge dele i legemet, hvilket kan føre til gigt af varierende grad. De omhandlede forbindelser kan anvendes til behandling af patienter, der kræver diuretisk og saluretisk behandling, uden at der er nogen risiko for at fremkalde gigt.
Fra de tycke offentligqørelsesskrifter nr. 1 958 918 og nr. 1 958 919 kendes indan-forbindelser med lignende virkning, men med en anden struktur, idet de kendte forbindelser ikke indeholder en 2,3-hydrocarbylen-kæde.
De således kendte forbindelser har dog ikke uricosure-tisk virkning.
Ved fremgangsmåden ifølge opfindelsen, der er ejendommelig ved det i kravets kendetegnende del anførte, fremstilles forbindelser med den i kravet angivne almene formel I, hvor R er hydrogen eller alkyl med 1-5 carbon-atomer, og Q er methylen, ethylen, trimethylen eller te-tramethylen, eller et ugiftigt farmaceutisk accepta- U6444 2 belt salt deraf med en base.
Ifølge en udførelsesform for fremgangsmåden fremstilles l-oxo-2,3-methylen-5-indanyloxy-eddikesyrerne ved 1,1'-cycloaddition af et methylenyleringsmiddel til en tilsvarende substitueret l-oxo-inden-5-yloxy-eddikesyre (II) efter følgende reaktionsskema: ^ g
HOOC-CH-CT
L H00C-CH20 hvori R har den i kravet angivne betydning. De som udgangsmaterialer anvendte (l-oxo-inden-5-yl-oxy)eddikesyrer er beskrevet i USA patent nr. 3 668 241.
l-oxo-2,3-hydrocarbylen-5-indanyloxy-eddikesyrerne kan ifølge en anden udførelsesform fremstilles ved en etheri-fikationsmetode, hvorved en halogeneddikesyre eller en ester deraf med formlen: 0 II 1 ZCH^C-OR-1 hvori R^ er hydrogen eller en alkylgruppe med 1-5 car-bonatomer, og Z er halogen, omsættes med en 2,3-hydro-carbylen-5-hydroxy-l-indanon (IV). Følgende skema viser denne reaktion: HO' R10-C-CH2Q'^ Ib ^ Hydrolyse, når R* er alkyl
Cl 0 R
HO-C-CH-iT^
2 I
146444 3 hvor R, R*, Q og Z har den ovennævnte betydning. Reaktionen udføres i nærværelse af en base, såsom et alkalime-talcarbonat, -hydroxid eller -alkoxid, såsom kaliumcarbo-nat, natriumcarbonat, natriumhydroxid eller natriumetho-xid. Ethvert opløsningsmiddel, der er inert eller i det væsentlige inert over for reagenserne, og hvori reagenserne har en rimelig opløselighed, kan anvendes. Acetone, ethanol og dimethylformamid har for eksempel vist sig særligt hensigtmæssige som opløsningsmidler. Reaktionen kan udføres ved en temperatur fra 25 °C til opløsningsmidlets kogepunkt. Reaktionen med halogeneddikesyren eller esteren er sædvanligvis afsluttet i løbet af 10 - 60 minutter. Hvis der anvendes en halogeneddikesy-reester,hydrolyseres den dannede ester til dannelse af den frie syre på i og for sig kendt måde.
De som udgangsmaterialer anvendte 2,3-hydrocarbylen-5-hy-droxy-l-indanoner (IV) fremstilles ved behandling af den tilsvarende substituerede 2,3-hydrocarbylen-5-alkoxy-l-indanon med et etherspaltningsreagens, såsom aluroinium-chlorid, pyridin-hydrochlorid eller natrium i flydende ammoniak. Hvis aluminiumchlorid anvendes, kan opløsningsmidlet være heptan, carbonsulfid eller methylenchlo-rid, og hvis man anvender pyridin-hydrochlorid, er det ikke nødvendigt at anvende et opløsningsmiddel. Følgende skema viser denne proces; 2)5¾. ,¾¾
V
2 hvor Q og R har den ovennævnte betydning, og R er alkyl.
De 2-substituerede Z,3-hydrocarbylen-5-alkoxy-l-indanoner (V) fremstilles ved behandling af en 2,3-hydrocarby len- 4 U6444 5-alkoxy-l-indanon (VI) med et tilsvarende alkyleringsmiddel med formlen: R'Z, hvor R' betegner alkyl med 1-5 carbonatomer, og Z har den i kravet angivne betydning. Denne reaktion udføres ved først at behandle en 2,3-hydrocarbylen-5-alkoxy-1-indanon (VI) med en base, f.eks. et alkalimetalhydrid, såsom natriumhydrid, eller et alkalimetalalkoxid, f.eks. kalium-tertiær-butoxid. Andre anvendelige baser er natrium-amid og lithiumamid. Denne basebehandlede forbindelse behandles derefter med alkyleringsmidlet R'Z.

Hvis denne situation eksisterer, kan de optiske antipoder adskilles ved de i det efterfølgende beskrevne metoder .
Adskillelsen af optiske isomere af de racemiske syrer kan udføres ved dannelse af et salt af den racemiske blanding med en optisk aktiv base, såsom ( + ) eller (-)-amphetamid, (-)-chinco-nidin, dehydroabiethylamin, (+) eller (-)-a-methylbenzyl-amin, ( + ) eller (-)-ol-(1-naphthyl)-ethylamin, brucin eller strychnin, i et opløsningsmiddel, såsom methanol, ethanol, 2-propanolbenzen, acetonitril, nitromethan eller acetone. På denne måde dannes i opløsningen to diastereo-mere salte, hvoraf det ene sædvanligvis er mere opløseligt i opløsningsmidlet end det andet- Gentagne omkrystallisationer af det krystallinske salt giver sædvanligvis en ren diastereomer. Den optisk rene l-oxo-2,3-hydrocar-bylen-5-indanyloxy-eddikesyre fås ved tilsætning af en mineralsyre til saltet, ekstraktion af den frigivne syre i ether, afdampning af opløsningsmidlet og omkrystallisation af den optisk rene antipode.
Den anden optisk rene antipode kan sædvanligvis fås ved anvendelse af en anden base til dannelse af det dia-stereomere salt. Det er fordelagtigt at anvende den partielt spaltede syre fra filtratet efter fraskillelsen af det ene diastereomere salt og yderligere at rense stoffet ved anvendelse af den anden optisk aktive base.
Fremgangsmåden ifølge opfindelsen forklares nærmere ved hjælp af følgende eksempler.
