Description
Analogifremgnagsmåte for fremstilling av Analogy method for the production of
terapeutisk virksomme 10,ll-dihydro-5H-dibenzo-|a,dj cyklohepten-derivater. therapeutically active 10,11-dihydro-5H-dibenzo-|a,dj cycloheptene derivatives.
Oppfinnelsens gjenstand er analogifremgangsmåter for fremstilling av nye 5-aminometylerte 10,ll-dihydro-5H-dibenzo-[a,d]cykloheptener av formelen: The object of the invention is analogous methods for the production of new 5-aminomethylated 10,11-dihydro-5H-dibenzo-[a,d]cycloheptenes of the formula:
i hvilken betyr et hydrogenatom eller en alkylgruppe med 1-3 in which means a hydrogen atom or an alkyl group of 1-3
karbonatomer, R2betyr en alkyl-, alkenyl- eller alkynylgruppe med 1-3 karbonatomer, R3betyr en alkylgruppe med 1-3 karbonatomer, og én av restene R^og R,- betyr et hydrogenatom og den andre et hydrogen- eller halogenatom, eller en alkylgruppe med 1-3 karbonatomer, samt syre-addisjonssalter herav, og fremgangsmåten erkarakterisert vedat enten carbon atoms, R2 means an alkyl, alkenyl or alkynyl group with 1-3 carbon atoms, R3 means an alkyl group with 1-3 carbon atoms, and one of the radicals R^ and R,- means a hydrogen atom and the other a hydrogen or halogen atom, or a alkyl group with 1-3 carbon atoms, as well as acid addition salts thereof, and the method is characterized by either
a) omsettes reaksjonsdyktige estere av alkoholer av formelen: a) reactive esters of alcohols of the formula are reacted:
har de foran anførte betydninger, med et amin av formelen HNR2R3, has the above meanings, with an amine of the formula HNR2R3,
hvor R2og R^har de foran anførte betydninger, eller where R 2 and R 2 have the previously stated meanings, or
b) primære eller sekundære aminer av formelen: b) primary or secondary amines of the formula:
i hvilken R1, R4og R,- har de foran anførte betydninger, og R' in which R 1 , R 4 and R 1 - have the meanings given above, and R'
betyr et hydrogenatom eller en alkyl-, alkenyl- eller alkynylgrup- means a hydrogen atom or an alkyl, alkenyl or alkynyl group
pe med 1-3 karbonatomer, alkyleres, alkenyleres eller alkynyleres til det ønskede tertiære amin, eller at man pe with 1-3 carbon atoms, is alkylated, alkenylated or alkynylated to the desired tertiary amine, or that one
c) for fremstilling av produkter i hvilke R2og R3betyr alkylgruppe r , spalter reduktivt kvartære ammoniumsalter av formelen: c) for the production of products in which R2 and R3 are alkyl groups, reductively split quaternary ammonium salts of the formula:
hvor R^, R2, R3, R4og R,- har de ovenfor anførte betydninger, og betyr en syrerest, eller at man d) for fremstilling av produkter i hvilke R2ogR3betyr alkyl grupper, hydrogenerer 5-aminometylerte 5H-dibenzo[a,d]cyklohepte-ner av formelen: where R^, R2, R3, R4 and R,- have the meanings given above, and means an acid residue, or that d) for the production of products in which R2 and R3 are alkyl groups, hydrogenate 5-aminomethylated 5H-dibenzo[a,d] cycloheptenes of the formula:
i hvilken , , R3, R4og R^har de foran anførte betydninger, in which , , R 3 , R 4 and R 4 have the above meanings,
hvorpå det erholdte reaksjonsprodukt isoleres som fri base, eller i form av et syreaddisjonssalt. whereupon the reaction product obtained is isolated as a free base, or in the form of an acid addition salt.
De nevnte forbindelser oppviser, slik som dette kan på-vises ved elektrosjokkforsøket [metode avGoodmann et al: "J.Pharmacol.", 108, 168(1953)], en sterk antikonvulsiv virksomhet, og kommer derfor særlig i betraktning som anti-epileptika. The mentioned compounds show, as can be demonstrated by the electroshock test [method of Goodmann et al: "J.Pharmacol.", 108, 168(1953)], a strong anticonvulsant activity, and therefore come particularly into consideration as anti-epileptics .
Det skal bemerkes at en analog av fremgangsmåteforbindel-sene , 5-(N-metylaminopropyl)-5H-dibenzo[a,d]cyklohepten, kjent som "Protriptyline" ikke har noen anti-konvulsiv virkning. It should be noted that an analogue of the process compounds, 5-(N-methylaminopropyl)-5H-dibenzo[a,d]cycloheptene, known as "Protriptyline" has no anticonvulsant effect.
Omsetningen av nevnte estere med et amin av formelen HNR2R.J kan finne sted ved moderat inntil sterk oppvarmning av de reaksjonsdeltagende stoffer i et passende inert oppløsningsmiddel, som benzen, toluen eller xylen og i nærvær av et overskudd av det anvendte amin eller esi annen syrebindende base som trietyl-amin. Som reaksjonsdyktige estere av alkoholer er særlig egnet halogenhydrogen- eller p-toluensulfonsyreestere. The reaction of said esters with an amine of the formula HNR2R.J can take place by moderate to strong heating of the substances participating in the reaction in a suitable inert solvent, such as benzene, toluene or xylene and in the presence of an excess of the amine used or some other acid-binding agent base such as triethylamine. As reactive esters of alcohols, halogen hydrogen or p-toluenesulphonic acid esters are particularly suitable.
De som utgangsstoffer nødvendige estere kan fåes ved forestring av tilsvarende alkoholer, f.eks. tionylklorid.Alko-holene kan på sin side fåes ved reduksjon av tilsvarende syrer, som på sin side igjen kan fåes fra de tilsvarende nitriler. The esters required as starting materials can be obtained by esterification of corresponding alcohols, e.g. thionyl chloride. The alcohols can in turn be obtained by reduction of corresponding acids, which in turn can be obtained from the corresponding nitriles.
Alkyleringen av de nevnte primære eller sekundære aminer kan finne sted ved omsetning med tilsvarende aldehyder under an-vendelse av et reduksjonsmiddel, som maursyre, eller, som også en alkenylering eller alkynylering, ved omsetning med reaksjonsdyktige estere av tilsvarende alkoholer, særlig halogenidene. The alkylation of the mentioned primary or secondary amines can take place by reaction with corresponding aldehydes using a reducing agent, such as formic acid, or, as also an alkenylation or alkynylation, by reaction with reactive esters of corresponding alcohols, especially the halides.
De som utgangsstoffer nødvendige primære aminer fåes fortrinnsvis ved reduksjon av tilsvarende nitriler. De sekundære aminer dannes f.eks. ved omsetning av reaksjonsdyktige estere av The primary amines required as starting materials are preferably obtained by reduction of corresponding nitriles. The secondary amines are formed e.g. by conversion of reactive esters of
alkoholer med aminer av formelen I^N-I^- alcohols with amines of the formula I^N-I^-
Den reduktive spaltning av de kvartære ammoniumsalter kan f.eks. gjennomføres med natriumamalgam i alkoholisk eller med Raney-nikkel-legering i alkalisk oppløsning. The reductive cleavage of the quaternary ammonium salts can e.g. carried out with sodium amalgam in alcoholic or with Raney-nickel alloy in alkaline solution.
De som utgangsstoffer anvendbare kvartære ammoniumsalter kan på sin side f.eks. fåes når 5,ll-metylenimino-10,11-dihydro-5H-dibenzo[a,d]cykloheptener av formelen: The quaternary ammonium salts that can be used as starting materials can, for their part, e.g. is obtained when 5,11-methyleneimino-10,11-dihydro-5H-dibenzo[a,d]cycloheptenes of the formula:

De ønskede forbindelser hvor R2 og r^ betyr alkylgrupper fåes sluttelig også når 5-amino-metylerte 5H-dibenzo[a,d]cyklo-heptener av formelen: The desired compounds where R 2 and r 2 mean alkyl groups are also finally obtained when 5-amino-methylated 5H-dibenzo[a,d]cycloheptenes of the formula:
i hvilken R^, R2, R^, R^og R5har de foran anførte betydninger, hydrogeneres. in which R 1 , R 2 , R 2 , R 2 and R 5 have the above meanings, is hydrogenated.
Hydrogeneringen finner fortrinnsvis sted i et organisk oppløsningsmiddel, f.eks. en alkohol eller ester, ved behandling med hydrogen i nærvær av en katalysator, som palladiumkull, Raney-nikkel, platina eller lignende. The hydrogenation preferably takes place in an organic solvent, e.g. an alcohol or ester, by treatment with hydrogen in the presence of a catalyst, such as palladium charcoal, Raney nickel, platinum or the like.
