Description
Fremgangsmåte til fremstilling av N-substituerte kamfidinforbindelser. Process for the preparation of N-substituted camphidin compounds.
Det har vist seg at de hittil ukjente It has been shown that the hitherto unknown
N-substituerte kamfidiner med den almin-nelige formel N-substituted camphidins of the general formula
i hvilken Ar betegner en usubstituert eller en med en eller flere substituenter av samme eller forskjellig art substituert fenylgruppe, i hvilken substituentene er halogenatomer eller alkyl-, alkoksy-, nitro-, amino- eller acyloksygrupper og n står for 1,2 eller 3, og deres syreaddisjonssalter eller kvaternære ammoniumsalter ved en lav toksisitet har verdifulle depressoriske virk-ninger på det sentrale nervesystem, som i noen grad ligner virkningen av reserpin, og derfor kan anvendes som beroligelsesmid-ler, d. v. s. såkalte tranquillizere. Ved for-søk med mus har forbindelsene utvist en sedativ eller stuporfremkallende virkning, og ennvidere har mange av forbindelsene potensert virkningen av barbiturater. Hos særdeles virksomme forbindelser av den angitte art er fenylgruppen substituert med en eller flere substituenter av samme eller forskjellig art, og som er halogenatomer, især kloratomer, eller alkyl- eller alkoksygrupper, fortrinnsvis lavmolekylære alkyl-eller alkoksygrupper med høyst tre karbonatomer, eller nitro- eller aminogrupper. Fenylgruppen kan dog også være substituert med andre substituenter, f. eks. acyloksygrupper, fortrinnsvis med høyst tre karbonatomer. De mest virksomme forbindelser av den angitte art synes å være N-(o-klorbenzyl)-kamfidin, N-(m-klorbenzyl)-kamfidin og N-(o-klorfenyl-fi-etyl)-kamfidin og disse forbindelsers syreaddisjonssalter, f. eks. med et hydrogen-halogenid så som hydrogenklorid eller svo-vel-, fosfor, eddik- eller vinsyre, eller kvaternære ammoniumsalter, især med en kvaternær alkylgruppe med høyst tre karbonatomer. Oppfinnelsen angår en fremgangsmåte til fremstilling av de nye N-substituerte kamfidinforbindelser, som består i at kamfidin eller kamfersyreimid kondenseres med et arylalkylhalogenid med den almene formel i hvilken Ar betegner en usubstituert eller substituert fenylgruppe og n står for 1, 2 eller 3, til et N-substituert kamfidin eller kamfersyreimid med den almene formel in which Ar denotes an unsubstituted or a phenyl group substituted with one or more substituents of the same or different kind, in which the substituents are halogen atoms or alkyl, alkoxy, nitro, amino or acyloxy groups and n stands for 1,2 or 3, and their acid addition salts or quaternary ammonium salts at a low toxicity have valuable depressant effects on the central nervous system, which to some extent resemble the effect of reserpine, and can therefore be used as sedatives, i.e. so-called tranquillizers. In experiments with mice, the compounds have shown a sedative or stupor-inducing effect, and furthermore many of the compounds have potentiated the effect of barbiturates. In particularly active compounds of the type indicated, the phenyl group is substituted with one or more substituents of the same or different type, and which are halogen atoms, especially chlorine atoms, or alkyl or alkoxy groups, preferably low molecular weight alkyl or alkoxy groups with no more than three carbon atoms, or nitro- or amino groups. However, the phenyl group can also be substituted with other substituents, e.g. acyloxy groups, preferably with no more than three carbon atoms. The most effective compounds of the type indicated appear to be N-(o-chlorobenzyl)-camphidine, N-(m-chlorobenzyl)-camphidine and N-(o-chlorophenyl-p-ethyl)-camphidine and the acid addition salts of these compounds, f e.g. with a hydrogen halide such as hydrogen chloride or sulfuric, phosphoric, acetic or tartaric acid, or quaternary ammonium salts, especially with a quaternary alkyl group with at most three carbon atoms. The invention relates to a process for the production of the new N-substituted camphidine compounds, which consists in camphidine or camphor imide being condensed with an arylalkyl halide with the general formula in which Ar denotes an unsubstituted or substituted phenyl group and n stands for 1, 2 or 3, to a N-substituted camphidine or camphor imide of the general formula
i hvilken X betegner O eller H2, og Ar og n har den ovenfor angitte betydning, hvoretter kondensasjonsproduktet, såfremt det er et N-substituert kamfersyreimid, redu-seres til det tilsvarende N-substituerte kamfidin, og det ved kondensasjon eller ved kondensasjon og reduksjon vundne N-substituerte kamfidin eventuelt ved reak-sjon med en uorganisk eller organisk syre eller et kvaterniseringsmiddel, f. eks. med et alkylhalogenid, som fortrinnsvis inneholder høyst tre karbonatomer, omdannes til et syreaddisjonssalt eller et kvaternært ammoniumsalt. in which X denotes O or H2, and Ar and n have the above meaning, after which the condensation product, if it is an N-substituted camphor imide, is reduced to the corresponding N-substituted camphidine, and that by condensation or by condensation and reduction obtain N-substituted camphidins optionally by reaction with an inorganic or organic acid or a quaternizing agent, e.g. with an alkyl halide, which preferably contains at most three carbon atoms, is converted into an acid addition salt or a quaternary ammonium salt.
For å oppnå et stort utbytte gjennom-føres kondensasjonen hensiktsmessig i nærvær av et basisk kondensasjonsmiddel, især et alkalimetallhydroksyd, fortrinnsvis opp-løst i en alkohol, f. eks. metanol eller etanol, men det kan også anvendes andre basiske kondensasjonsmidler, f. eks. alka-limetallamider, så som natriumamid. Re-duksjonen gjennomføres lettest med et hydrid, fortrinnsvis litiumaluminiumhydrid, men den kan også bevirkes på annen måte, f. eks. ved katalytisk hydrer-ing eller ved elektrolytisk reduksjon. In order to achieve a high yield, the condensation is conveniently carried out in the presence of a basic condensation agent, in particular an alkali metal hydroxide, preferably dissolved in an alcohol, e.g. methanol or ethanol, but other basic condensation agents can also be used, e.g. alkali metal amides, such as sodium amide. The reduction is most easily carried out with a hydride, preferably lithium aluminum hydride, but it can also be effected in another way, e.g. by catalytic hydrogenation or by electrolytic reduction.
Ved en endret utførelsesform for frem-gangsmåten fremstilles de N-substituerte kamfidinforbindelsers kvaternære ammoniumsalter ved kvaternisering av et N-alky! -kamfidin, hvis alkylgruppe fortrinnsvis inneholder høyst tre karbonatomer, ved omsetning med et arylalkylhalogenid med den almene formel In a modified embodiment of the method, the N-substituted camphidine compounds' quaternary ammonium salts are prepared by quaternization of an N-alky! -camphidine, whose alkyl group preferably contains at most three carbon atoms, by reaction with an arylalkyl halide of the general formula
Hal - (CH2)„-Ar, Hal - (CH2)„-Ar,
i hvilken Ar betegner en usubstituert eller substituert fenylgruppe og n står for 1, 2 eller 3, hvoretter det vundne kvaternære ammoniumsalts anion om ønsket på sed-vanlig måte utskiftes med en annen anion. in which Ar denotes an unsubstituted or substituted phenyl group and n stands for 1, 2 or 3, after which the anion of the quaternary ammonium salt obtained is, if desired, replaced in the usual way with another anion.
Eksempel 1. Example 1.
I en oppløsning av 11,3 g kalium-hydroksyd (85 pst. renhet) i 165,5 ml absolutt etanol oppløses 30 g kamfersyreimid, hvorpå 26,7 g p-klorbenzylklorid tilsettes. Blandingen omrystes og står 22 timer ved stuetemperatur, hvoretter den under til-bakekjøling kokes 2 timer. Reaksjonsblandingen filtreres, og til filtratet settes vann. Ved avkjøling utskilles 23,7 g N-p-klorben-zylkamfersyreimid i form av smukke krys-taller med smeltepunkt 102—104°C. In a solution of 11.3 g of potassium hydroxide (85% purity) in 165.5 ml of absolute ethanol, 30 g of camphor imide is dissolved, after which 26.7 g of p-chlorobenzyl chloride is added. The mixture is shaken and left for 22 hours at room temperature, after which it is boiled for 2 hours under re-cooling. The reaction mixture is filtered, and water is added to the filtrate. On cooling, 23.7 g of N-p-chlorobenzylcamphoric acid imide is separated in the form of beautiful crystals with a melting point of 102-104°C.
I en trehalset kolbe forsynt med meka-nisk omrører, skilletrakt og tilbakekjøler med CaCl2-rør, anbringes 6,75 g litiumaluminiumhydrid i 135 ml tørr eter. Under omrøring tildryppes langsomt en oppløsning av 23,65 g N-p-klorbenzyl-kamfersyreimid i 200 ml tørr eter. Reaksjonsblandingen står 16 timer og kokes deretter 4,5 timer under tilbakesvaling. Etter avkjøling tildryppes langsomt først 8,4 ml vann, deretter 8,4 ml 15 pst.'s natriumhydroksyd-oppløsning og til slutt 29,5 ml vann. Etter 90 minutters omrøring ved stuetemperatur suges aluminiumhydroksydbunnfallet fra og vaskes med 5 x 60 ml eter. Den samlede eteroppløsning tørres over magnesiumsul-fat, hvoretter eteren avdestilleres. Destillasjonsresten vakuumdestilleres, og fraksjo-nen med kokepunkt 128—179° C/0,7—0,9 In a three-necked flask equipped with a mechanical stirrer, separatory funnel and reflux condenser with a CaCl2 tube, 6.75 g of lithium aluminum hydride are placed in 135 ml of dry ether. While stirring, a solution of 23.65 g of N-p-chlorobenzyl-camphoric acid imide in 200 ml of dry ether is slowly added dropwise.
