Description
Den foreliggende oppfinnelse vedrører karboksyalkensyrer, som er karakterisert ved at de har den generelle formel
hvori
R er aminotiazolyl eller aminotiadiazolyl som eventuelt er beskyttet med en aminobeskyttende gruppe valgt fra benzyloksykarbonyl, metylbenzyloksykarbonyl, t-butoksykarbonyl, formyl, kloracetyl, dimetyl-t-butylsilyl, metoksyetoksymetyl og p-nitrobenzal,
R<2> er lavere alkylen, og
R<3> er hydrogen, alkalimetall, lavere alkyl, lavere alkenyl som eventuelt er substituert med fenyl, en eller to fenylalkyl-grupper som eventuelt er substituert med metyl, metoksy eller nitro, eller lavere alkanoyloksyalkyl.
Forbindelsene er egnet for fremstilling av terapeutisk aktive 7-(3- (karboksyalkenoylamino) -3-cef em-4-karboksylsyre-forbindelser med den generelle formel:
eller farmasøytisk talbare salter derav,
hvori
R er 2-aminotiazolyl eller 2-aminotiadiazolyl
R2 er lavere alkylen;
R<3> og R<6> er hver hydrogen, alkalimetall eller lavere alkanoyl-oksy-lavere alkyl; og
R<5> er hydrogen, metyl, metoksymetyl, acetoksymetyl, karbamoyl-oksymetyl, metyltiometyl, cyanometyltiometyl, difluormetyltiometyl, triazolyltiometyl, tiadiazolyltiometyl, eller tetra-zolyltiometyl, (hver av disse heterosykliske forbindelser eventuelt substituert med metyl, amino eller aminometyl), vinyl (eventuelt substituert med cyano, karboksy eller tri-fluormetyl), metoksy, mesyloksy,
2-fluoretyltio, difluormetyltiometyl, trifluoretyltio, vinyl-tio, halogen eller pyridiniometyl.
Disse terapeutisk aktive forbindelser er midler mot aerobe grampositive bakterier, men mer spesielt er forbindelsenes høye antigramnegative potens, høye adsorpsjon, ekskresjon, distribusjon o.l. bemerkelsesverdige.
R<3> som en karboksymodifiserende gruppe er foretrukket en esterdannende gruppe eller saltdannende atom eller gruppe som er nyttig som en karboksybeskyttende gruppe eller for et medisinsk virkende derivat.
Fremstilling av karboksyalkensyrer
Disse karboksyalkensyrene er nye forbindelser fremstilt ved hjelp av en Wittig-type reaksjon av formylacetat (IV) eller dets enol eller acetal med alkylidentriarylfosforan (V) ved oppvarming, f.eks. ved 30 til 120'C i 1 til 10 timer, til å gi den ikke-konjugerte ester (VI) hvis dobbeltbinding vandrer til å gi konjugatesteren (VII):
hvori R, R<2> og R<3> er som tidligere angitt, og
hvori R<20> er alkylen,
eller av oksalat (VIII) med alkylidentriarylfosforan (IX), f.eks. ved 30 til 120°C i 1 til 10 timer til å gi konjugatesteren (VII).
Alternativt kan slike syrer eller estere, hvor R står for aminotiazolyl, fremstilles ved hjelp av en ringslutning av haloacetylkarboksylsyre (X) med eventuelt N-beskyttet tiourea
(XI) i alkohol ved 30 til 90<*>C i 1 til 5 timer og fører til aminotiazolesteren (XII):
hvori R<21> er hydrogen eller aminobeskyttende gruppe og R, R<2> og R<3> har tidligere anførte betingelser.
Når R<3> i den konjugerte syre (VII) eller (XII) er en karboksybeskyttende gruppe kan denne avbeskyttes på konvensjonell måte ved behandling med syre, base, Lewis-syre og kationreagens, hydrogen og katalysator, eller lignende til å gi den tilsvarende fri syre, foretrukket i et inert løsningsmiddel ved
-60 til 100<*>C i 1/6 til 10 timer.
Representative synteser av karboksyalkensyrene gis i det etterfølgende.
Reaksjonsbetingelser
De nevnte reaksjoner kan vanligvis gjennomføres ved -60 til 120'C, foretrukket ved -20 til 80<*>C i fra 10 minutter til 10 timer avhengig av reaksjonstypen. Reaksjonen foregår i et løsningsmiddel. Andre konvensjonelle betingelser (f.eks. omrøring, rysting, inert gass-dekning, tørking) kan anvendes.
Eksempler på typiske reaksjonsløsningsmidler er hydrokarboner (f.eks. pentan, heksan, oktan, benzen, toluen, xylen), halo-hydrokarboner (f.eks. diklormetan, kloroform, karbontetraklorid, dikloretan, trikloretan, klorbenzen), etere (f.eks. dietyleter, metylisobutyleter, dioksan, tetrahydrofuran), ketoner (f.eks. aceton, metyletylketon, cykloheksanon), estere (f.eks. etylacetat, isobutylacetat, metylbenzoat), nitrohydrokarboner (f.eks. nitrometan, nitro benzen), nitriler (f.eks. acetonitril, benzonitril) ,
amider (f.eks. formamid, acetamid, dimetylformamid, dimetyl-acetamid, heksametylfosfortriamid), sulfoksyder (f.eks.
dimetylsulfoksyd), karboksylsyre (f.eks. maursyre,
eddiksyro, propionsyre), organiske baser (f.eks. diatylamia trietylamin, pyridin, picolin, collidin, kinolin),
alkoholer (f.eks. metanol, etanol, propanol, heksanol, oktanol, benzylalkohol), vann, og andre industrielle løsningsmidler og blandinger derav.
Produktene kan oppnås fra en reaksjonsblanding ved å
fjerne forurensende bestanddeler (f.eks. løsningsmidler, uomsatte utgangsmaterialer, biprodukter) ved hjelp av en konvensjonell metode (f.eks. ekstraksjon, inndamping, vasking, konsentrering, utfelling, filtrering, tørking) og isolering av produktet ved hjelp av vanlig opparbeidelse (f.eks. ved adsorbsjon, eluering, destillasjon, utfelling, separering, kromatografering) eller en kombinasjon av de nevnte metoder.
De følgende eksempler illustrerer fremstilling av karboksyalkensyrene i henhold til oppfinnelsen. Ytterligere karboksyalkensyrer i henhold til oppfinnelsen er angitt i tabellen til slutt i beskrivelsen.
I eksemplene angir "deler" vektdeler og "ekvivalenter"
angir mol-ekvivalenter av beta-laktam-utgangsmaterialet Symbolene "cis" og "trans" viser relative stillinger for amido- og karboksyl-substituentene knyttet til sidekjede-dobbeltbindingen. Fysikalsk-kjemiske konstanter av produktene er oppsummert i tabellen hvori IR angis i cm verdi, NMR viser 6-verdi og jod-verdien viser koblingskonstantene i Hz-skala. i nmr av en geometrisk isomerblanding er signaler som splittes i to eller flere vist ved kjemiske skiftinger separert med komma og oppspilttingstall og "X" før flertalls-markeringen.
Vanligvis blir reaksjonsblandingen om nødvendig etter tilsetning av et løsningsmiddel (f.eks. vann, syre, diklormetan) vasket, tørket, og konsentrert og produktet separeres. All konsentrering foretas under redusert trykk.
(Forkortelser) AOM = acetoksymetyl; BH = difenyImetyl (=benz-hydryl); Bu = butyl; BOC = t-butoksykarbonyl; Bzl = benzyl; Cbz = benzyloksykarbonyl; sirkel i en heteroring av struktur-formelen betyr at ringen er aromatisk; exo = 3,4-dobbelt-bindings-posisjonsisomer i 7-sidekjedeacyl; Me = metyl; MEM-metoksyetoksymetyl; Ph = fenyl; PMB = p-metoksybenzyl, PNB = p-nitrobenzyl; POM = pivaloyloksymetyl; og HCO = formyl.
