Description
Fremgangsmåte for fremstilling av terapeutisk virksomme,
hittil ukjente substituerte 6,7-benzomorfaner-
Nærværende oppfinnelse vedrorer en fremgangsmåte for fremstilling av hittil ukjente benzomorfanderivater med verdi-
fulle farmakologiske egenskaper.
Det ble overraskende funnet at forbindelser med den generelle formel I, hvor betyr hydrogen, hydroksylgruppen eller en lavere alkanoyloksyrest,
1*2 en lavere alkyl eller P-metoksyetylrest eller en fenylrest,
R 3 hydrogen eller en lavere alkylrest og
R 4 en lavere alkyl- eller en fenylrest,
innehar verdifulle farmakologiske egenskaper, i særdeleshet analgetisk virkning.
Mange av disse forbindelser er i motsetning til morfin og
andre kjente benzomorfaner, overraskende fri for sykdomsfrem-bringende egenskaper. Videre viser de nye benzomorfaner en antitussiv virkning, og noen av dem er antagonister av morfin.
Forbindelsene kan anvendes parenteralt eller oralt i en
vanlig farmasoytisk administråsjonsform, dvs. i form av
tabletter, kapsler, pulver, suspensjoner, opplbsninger, siruper osv. Av spesiell fordel er former med forsinket aktivstoff-frigivelse, som kan fremstilles efter en eller annen kjent fremgangsmåte.
I forbindelsene med den generelle formel I er foruten hydrogen hydroksylgruppen acetoksy-, propionoksy- eller butyroksyresten.| R2er en lavere alkylrest, som i særdeleshet metyl-, etyl-, n-propyl-, isopropyl, n-butyl-, isobutyl, sek. butyl-, tert. butyl-, n-pentylresten, p-metoksyetylresten eller en
fenylrest. R^er foruten hydrogen en lavere alkylrest, som ;
i særdeleshet metyl-, videre etyl-, n-propyl- eller isopropyl-resten. R^er foruten fenylresten en lavere alkylrest, som f.eks. metyl-, etyl-, n-propyl-, isopropyl-, n-butyl-, iso~.-- . •
butyl-, sek. butyl-, tert. butyl- eller n-amylresten.
Fremstillingen av forbindelser med den generelle formel I finner sted ved at man omsetter en forbindelse med den generelle formel II,
hvor betyr hydrogen eller en lavere alkylrest, og R^, R» og R.j har de under formel I angitte betydninger, med et karbonsyrederivat med den generelle formel III,
hvor Hal betyr et halogenatom og
R^har de under formel I angitte betydninger,
og, hvis bnsket, ifall R.^ betyr en alkanoyloksygruppe, hydrolyserer på i og for seg kjent måte. . Forbindelser med den generelle formel II oppnår man f.eks. i ved cyklisering av en forbindelse med den generelle formel IV,
i
hvor R5' har betydningen for Rj- med unntagelse av hydrogen og
R^, R^og R^har de under formel I angitte betydninger, i nærvær av en Lewis-syre til en forbindelse med den generelle formel Ila:
Disse forbindelser er, hvis onsket, med bromcyan-avbygnings-reaksjonen efter Braun overforbare til forbindelser med den generelle formel Ilb,
hvor R^, R£og R^har de under formel I angitte betydninger. Som karbonsyrederivater med den generelle formel III er f.eks. folgende egnet: klorkarbonsyremetyl-, -etyl-, -propyl-, -butyl-, -amyl-, såvel som-fenylester, som også de tilsvarende bromderivater.
Som alkyleringsmidler, dvs. for omvandlingen av 2'-hydroksylgruppen til en lavere alkoksygruppe kommer i særdeleshet diazoalkaner, som f.eks. diazometan, på tale.
Som alkanoyleringsmidler, dvs. for omvandlingen av 2'-hydroksylgruppen til en lavere alkanoyloksygruppe, egner seg fremfor alt reaksjonsdyktige funksjonelle derivater av lavere alkankarboksylsyrer, som f.eks. anhydrider og halogenider, som eddiksyreanhydrider, propionsyreanhydrider, acetylklorid, acetylbromid, propionylklorid såvel som propionylbromid.
Ifall R^ betyr en lavere alkanoyloksygruppe, kan man hydrolysere en slik på i og for seg kjent måte, f.eks. ved innvirkning av en vandig mineralsyre eller en lut.
; Det er av fordel å gjennomføre omsetningen ifolge oppfinnelsen i et egnet inert organisk opplosningsmiddel, som i særdeleshet ; toluen eller vannfri benzen, hvorved vanligvis det arbeides i ved forhoyet temperatur, som f.eks. ved koketemperaturen for i reaksjonsblandingen. Omsetningen kan også gjennomfores i en inert atmosfære, f.eks under nitrogen.
Som det går frem av formel I, kan forbindelsene ifolge opp finnelsen eksistere i optisk isomere former. Således forer nærværet av et asymetrisk karbonatom i morfanringen til dannelsen av d- og l-former. Er R, i formel I en alkylrest, så er stereoisomerer mulig, hvorved alkylgruppen kan være bundet cis eller trans til resten R_ i 5-stilling.
De geometriske eller stereoisomere formene kan skilles,
hvis onsket, på i og for seg kjent måte, f.eks. ved franksjonert krystallisasjon eller ved destillasjon.
Vil man skille enantiomorfe former, så dannes på vanlig måte under anvendelse av en optisk aktiv syre de diastereoisomere saltene. Alle disse isomere formene er likeledes gjenstand for oppfinnelsen.
De efterfblgende eksempler illustrerer gjennomfbringen av fremgangsmåten ifolge oppfinnelsen. Temperaturene er angitt i Celsiusgrader.
