Description
Fremgangsmåte til fremstilling av nye «-amino-/?-oksykarbonsyreamider.
Gjenstanden for foreliggende oppfin-nelse er en fremgangsmåte til fremstilling
av nye a amino- p-oksykarbonsyreamider.
Det er kjent, at p-fenetidider av a-ami-nokarbonsyrer, f. eks. N-acetyl-glyssin-p-fenetidid eller glycin-p-fenetidid henholdsvis deres salisylsure salter har antipyretiske
og antineuralgiske egenskaper.
Det ble nå funnet, at a-amino-p-oksykarbonsyreamider med den generelle formel
hvori R betyr en alkylrest med høyst fire kullstoff atomer eller en fenylrest, R, betyr et vannstoffatom eller en alkylrest med høyst fire kullstoff atomer, R2 betyr en eventuelt med en laveremolekylar oksal-kylrest eller en laveremolekylar karbalkok-sygruppe substituert fenylrest, idet R1 og R2 også sammen med det forbundne kvel-stoffatom kan være ledd i et mettet heterocyklisk ringsystem, ved siden av antiflo-gistiske og antipyretiske egenskaper har en overordentlig god analgetisk virkning ved forholdsvis liten tokisisitet og at man kan fremstille slike forbindelser idet man behandler forbindelser med den generelle formel
hvori R, R, og R2 har den angitte betydning, med salpetersyrling og i nitroseringsproduktene reduserer isonitrosogruppen og ketogruppen.
Som utgangsstoffer kommer for. fremgangsmåten ifølge oppfinnelsen forbindelser med ovenfor angitt formel på tale hvori R, R, og R2 har den nevnte betydning. Særlig er forbindelser med den angitte formel egnet, hvor R betyr en metylgruppe og R2 en med en laveremolekylar oksalkyl-gruppe i p-stilling substituert fenylrest eller hvor kvelstoffatomet i aminogruppen er ledd i et mettet heterocyklisk ringsystem.
F. eks. skal følgende forbindelser nevnes: aceteddiksyre-p-fenetidid, bensoyleddiksyre-p-fenetidid, aceteddiksyre-anilid, aceteddiksyre-p-anisidid, p-nitrobensoyl-edikksyre-p-fenetidid, m-oksy-bensoyleddiksyre-p-fenetidid, o-metoksy-bensoyleddiksyre-p-fenetidid.
Aceteddiksyre-N-metyl-p-fenetidid, bensoyleddiksyre-N-etyl-p-fenetidid, aceteddiksyre-N-isobutyl-anilid, aceteddiksyre-N-n-butyl-p-anisidid, m-oksy-bensoyleddiksyre-N-n-propyl-p-fenetidid, o-metoyksy-bensoyleddiksyre-N-isopropyl-p-fenetidid.
Aceteddiksyre-piperidid, aceteddiksyre-1, 2, 3, 4-tetrahydrokinolid, aceteddiksyre-1, 2, 3, 4-tetrahydro-6-oksykinolid, aceteddiksyre-1, 2, 3, 4-tetrahydro-6-metoksy-kinolid, acetéddiksyre-morfolid, aceteddiksyre-pyrrolidid, aceteddiksyre-4-fenyl-4-karbetoksy-piperidid, aceteddiksyrepikolid (a, |3, y). aceteddiksyre-tiazolidid, aceted-diksyrerdekahydrokinolid, aceteddiksyre-6-isobutoksy-1, 2, 3, 4-tetrahydrokinolid, aceteddiksyre-dekahydro-iso-kinolid. Aceteddiksyre-1, 2, 3, 4-tetrahydro-isokinolid, aceteddiksyre-p-karbetoksy-anilid, aceteddiksyre-p-karbmetoksy-anilid, aceteddiksyre-o-karbetoksy-anilid, bensoyleddiksyre-(N-metyl)-p-karbetoksy-anilid, aceteddiksyre-(N-etyl)-p-karbmetoksy-anilid, p-metoksy-bensoyl-eddiksyre-(N-metyl)-p-karbetoksy-anilid, aceteddiksyre- (N-butyl) -p-karbmetoksyanilid,. aceteddiksyre-(N-propyl)-p-karbpropoksy-anilid.
De som utgangsstoffer anvendte forbindelser kan fremstilles i overensstem-melse med de i eksemplene angitte frem-gangsmåter (smnl. «Beilstein» (4. opplag), 1. Ergånzungswerk, bind 13, side 177).
Overføringen av utgangsstoffene til a-isonitrosoforbindelsene kan foretas ved nitrosering av a-stående kullstoffatom på kjent måte. Fortrinnsvis oppløser man (3-ketokarbonsyreamidet i iseddik og utfører nitroseringen ved tilsetning av en konsentrert vandig oppløsning av natriumnitrit. Man kan også oppløse p-ketokarbonsyrea-midet i et organisk oppløsningsmiddel og foreta nitroseringen ved tilsetning av natriumnitrit og mineralsyrer. Som organisk oppløsningsmiddel kommer f. eks. lavereali-fatiske alkoholer, særlig metanol, på tale. Som mineralsyrer anvendes fortrinnsvis svovelsyre eller saltsyre.
Reduksjonen av den a-stående isoni-trosogruppe kan ifølge fremgangsmåten ifølge oppfinnelsen utføres samtidig med reduksjonen av ketogruppen i ett arbeidsfor-løp. Reduksjonen kan f. eks. foretas katalytisk ved hjelp av metaller fra den åttende gruppe i det periodiske system, fortrinnsvis med nikkel-katalysatorer. For eksempel kan også anvendes edelmetaller eller Raney-katalysatorer. Som oppløsnings-middel kan det anvendes organiske oppløsningsmidler fortrinnsvis lavere alifatiske alkoholer, eventuelt i nærvær av vann. Man arbeider hensiktsmessig ved romtemperatur eller middels forhøyet tem-peratur, fortrinnsvis mellom 50—100° C. Videre kan man også redusere med nascerende vannstoff, f. eks. av natrium- eller aluminiumamalgam <p>g alkohol, med litium-aluminiumhydrid eller med natriumborhydrid. Reduksjonen kan også gjennomføres elektrolytisk. Etter fjernelse av katalysatoren får man direkte det ønskede a-amino-p-oksy-karbonsyreamid.
En likeledes fordelaktig utførelsesform for fremgangsmåten til overføring av de som mellomprodukt dannede isonitrosofor-bindelser til a-amino-p-oksy-karbinsyre-amider består i den arbeidsmåte som er beskrevet i det følgende, som kan utføres med gode utbytter. Man behandler derved først isonitrosoforbindelsene med reduser-ende midler på den måte, at bare isonitrosogruppen omdannes til aminogruppen.Som reduksjonsmiddel kommer f. eks. på tale: nascerende vannstoff, som f. eks. kan frém-stilles av uedle metaller, slik som sink, jern eller tinn, i nærvær av fortynnete syrer. Likeledes kan f. eks. også natriumhydrosul-fit eller tinnkloryr tjene som reduksjonsmiddel.
Reduksjonen av ketogruppen i a-amino-p-ketoforbindelsene til sekundære alko-holgruppe utføres deretter i en særskilt reaksjon. Derved kan det være fordelaktig,
å beskytte den a-stående aminogruppe
intermediært ved acylering. Som acylerende midler kommer syrederivater, f. eks. syrehalogenider, og syreanhydrider, f. eks. acetylklorid, propionylklorid, bensoylklorid, fenyleddiksyreklorid henholdsvis de tilsvarende syreanhydrider, særlig eddiksyrean-hydrid og fenyleddiksyreklorid på tale. Det er ved denne arbeidsmåte ikke nødvendig å isolere de intermediært dannede a-aminoforbindelser. Man kan foreta tilsetningen av acyleringsmidlet umiddelbart etter avslutning av reduksjonen av isonitrosogruppen. I tilfelle av anvendelse av nascerende vannstoff, som ble satt i frihet av uedle metaller ved hjelp av syrer, som reduksjonsmiddel, kan oppløsningen før tilsetningen av acyleringsmidlet avstumpes med natriumacetat.
Reduksjonen av ketogruppen kan f. eks. utføres ved hjelp av natrium- eller aluminiumamalgam i nærvær av alkoholer. Man kan også arbeide med litiumaluminium-hydrid eller natriumborhydrid samt elektrolytisk. En katalytisk hydrering utføres med særlig godt resultat idet det f. eks. kan anvendes katalysatorer fra den åttende gruppe av det periodiske system, fortrinnsvis nikkelkatalysatorer; med fordel kan også Raney-katalysatorer anvendes. Som oppløsningsmiddel kan organiske oppløs-ningsmidler, fortrinnsvis lavere alifatiske alkoholer, eventuelt i nærvær av vann, anvendes. Man arbeider hensiktsmessig ved romtemperatur eller middels forhøyde tem-peraturer, fortrinnsvis mellom 50—100°.
Avspaltningen av acylgruppen i de erholdte a-acylamino-p-oksykarbonsyreamider kan foretas etter vanlige fremgangsmå-ter, f. eks. ved forsåpning med fortynnede mineralsyrer, fortrinnsvis med halogen-vannstoffsyrer, særlig med klorvannstoffsyre eller bromvannstoffsyre.
Man kan ifølge den sist beskrevne fremgangsmåte også arbeide uten isolering av a-isonitroso-p-ketokarbonsyreamidene, idet man nitroserer utgangsforbindelsene, slik som beskrevet, med natriumnitrit i nærvær av syrer og reduserer direkte den erholdte reaksjonsblanding. Ved tilsetning av acyleringsmidlet etter avsluttet reduk-sjon fåes i dette tilfelle straks a-acylamino-p-ketokarbonsyreamid.
De erholdte forbindelser lar seg ved omsetning med anorganiske og organiske syrer, overføre til de tilsvarende salter. Som anorganiske syrer kommer f. eks. halogen-vannstoffsyrer, slik som klorvannstoffsyre og bromvannstoffsyre, svovelsyre, fosfor-syre og amidosulfonsyre i betraktning.
Som organiske syrer skal f. eks. nevnes: maursyre, eddiksyre, oksalsyre, malonsyre, ravsyre, maleinsyre, melkesyre, eplesyre, vinsyre, sitronsyre, oksetansulfonsyre, ace-tursyre, etylendiamintetraeddiksyre, ben-soesyre og salisylsyre samt deres derivater eller fenyldimetylpyrazolonmetylamino-metansulfonsyre.
De forbindelser som fåes ifølge fremgangsmåten ifølge oppfinnelsen er verdi-fulle legemidler, av hvilke mange utmerker seg ved liten toksisitet ved antiflogistisk, antipyretisk og analgetisk virkning og dess-uten har en sedativ komponent.
De er i sin virkning overlegne likeoverfor tilsvarende kjente forbindelser, f. eks. glysin-p-fenetididderivatene og N- acetyl-p-fenetidinet. Produktenes toksisitet er vesentlig mindre en for de nevnte kjente forbindelser. F. eks. er den analgetiske virkning av a-amino-p-oksy-smørsyre-6-metoksy-1, 2, 3, 4-tetra-hydrokinolid sterkere enn for det kjente N-acetyl-p-fenetidin, mens f. eks. a-amino-p-oksy-smørsyre-p-fenetidid utmerker seg ved en sterk antiflogistisk virkning samt både ved aerosil-prøver hos rotter og også ved allergisk kon-junktivitt hos kaniner med påfallende lang virkningstid.
En videre vesentlig fordel for forbin-delsene som kan fåes ifølge oppfinnelsen likeoverfor den kjente forbindelse ligger i den bedre oppløselighet. En del a-amino-p-oksy-smørsyre-6-metoksy-l, 2, 3, 4-tetra-hydrokinolid er godt oppløselig ved romtemperatur i 10 deler vann, mens den kjente forbindelse er å anse som praktisk talt vannuoppløselig og av det kjente N-acetyl-glycin-p-fenetidid-hydroklorid er bare en del oppløselig i 20 deler vann. Den dermed forbundne fordel som også er forbundet med en forbedret resorberbarhet, er særlig av betydning for den parenterale anvendelse av forbindelsen ifølge oppfinnelsen.

Hensiktsmessig avkjøles det peri-odevis. Etter ca. 15 minutter innføres denne oppløsning i en blandng av 1,5 kg is og 270 cm» konsentrert svovelsyre. Derved faller den dannede isonitrosoforbindelse ut. Etter tilsetning av 120 g sinkstøv til reaksjonsblandingen og en times omrøring inn-trer nesten fullstendig oppløsning.
