beskriver fremstilling av 2-trityl-5-fenyltetrazol.
Ifølge oppfinnelsen er det tilveiebrakt nye forbindelser av formel I som er tetrazolmellomprodukter som er anvendbare for fremstilling av antihypertensive forbindelser. Disse tetrazoler ér kjennetegnet ved at de har formelen
hvori
X<1> er H, -Sn(R)3, -C( fenyl )3 eller p>-nitrobenzyl, X<2> er H, Br eller
R er methyl eller fenyl; forutsatt at når X<1> er H kan X<2> ikke være
Spesielt foretrukne forbindelser er de av formel (I)
hvori:
(1) X<1> er H, -Sn(R)3 eller -C( fenyl )3,
(2) X<1> er H, -Sn(R)3 eller -C( fenyl)3 og X<2> er H, i (3) X<1> er -C( fenyl )3 og X<2> er Br og (4) X1 er -Sn(CH3)3 eller -C( fenyl )3 og X<2> er
De nye forbindelser av formel (I) kan fremstilles under anvendelse av de reaksjoner og teknikker som er beskrevet i dette avsnitt. Reaksjonene utføres i et løsningsmiddel som er egnet for de reagenser og materialer som anvendes og som er egnet for denne omdannelse som utføres. Det vil forstås av fagmannen at funksjonaliteten tilstedeværende på imidazolen og andre deler av molekylet, må være i overensstemmelse med den foreslåtte kjemiske omdannelse. Dette vil hyppig nødvendiggjøre bedømmelse med hensyn til rekkefølgen av syntesetrinn, de nødvendige beskyttende grupper, avbeskyttelsesbetingelser, og aktivering av en benzylisk posisjon for å muliggjøre binding til nitrogenet på imidazolkjernen. I det etter-følgende avsnitt kan ikke alle forbindelser av formel (I) som faller inn under en gitt klasse, nødvendigvis fremstilles ved alle metoder beskrevet for denne klasse. Substituenter på utgangsmaterialene kan være uforenlige med enkelte av de reaksjonsbetingelser som kreves i enkelte av de beskrevne metoder. Slike begrensninger med hensyn til substituentene som er forenlige med reaksjonsbetingelsene, vil lett fremgå for fagmannen, og alternative metoder må da anvendes.
Forbindelser av formel (I) hvori X<1> er Sn(R)3 og R er methyl og X<2> er substituert imidazolyl som ovenfor angitt, kan fremstilles ved 1,3-dipolar cycloaddi-
sjon av trialkyltinn eller trifenyltinnazider til det egnede, substituerte nitril (II) (reaksjonsskjema I). Et eksempel på denne teknikk er beskrevet av S. Kozima et al., J. Organometallic Chemistry, 33_, 337 (1971). Nitrilet (II) er beskrevet i US patentsøknad 884.920 innlevert 11. juli
1986. Andre nødvendige nitriler og trialkyl- eller triaryltinnazider er enten tilgjengelige kommersielt, eller kan fremstilles under anvendelse av teknikker og metoder beskrevet i litteraturen, J. Luijten et al., Ree. Trav. Chem., 81, 202 (1962).
Reaksjonsskjerna I
Forbindelser av formel (I) hvori X<1> og X<2> er H, kan fremstilles ved fjerning av en egnet beskyttende gruppe på tetrazolkjernen. Egnede beskyttende grupper for tetrazoldelen innbefatter p-nitrobenzyl, £-propionitril, trifenylmethyl og trialkyltinn, som fremstilles via de etterfølgende metoder. Nitrobenzylbeskyttelsesgruppen bindes som vist i reaksjonsskjerna II. Syren (IV) omdannes til syreklorid-mellomproduktet med oxalylklorid under standardbetingelser. Syrekloridet omdannes til amidet (V) ved kondensasjon med 4-nitrobenzylamin-hydroklorid i pyridin i nærvær av en katalytisk mengde 4-dimethylaminopyridin (DMAP). Amidet (V) omdannes til iminoylklorid-mellomproduktet via omsetning med fosforpentaklorid i carbontetraklorid. Ett eksempel på denne metode er beskrevet av H. Ulrich, The Chemistry of Imidoyl Halides, Plenum Press, N.Y., N.Y. (1968). Iminoylklorid-mellomproduktet omdannes til tetrazol (VI) med lithiumazid i dimethylformamid (DMF). Et eksempel på denne metode er beskrevet av Elderfield, Heterocyclic Compounds, John Wiley and Sons, (1967). Den beskyttede tetrazol (VI) hydrogeneres deretter ved 3,5 kg/cm<2> i nærvær av en katalytisk mengde av W6 Raney-nikkel i ethanol under dannelse av (I). Den nødvendige syre (IV) er tilgjengelig kommersielt eller kan fremstilles under anvendelse av teknikker og metoder beskrevet i den kjemiske litteratur.
Trifenylmethylgruppen bindes som vist i reaksjonsskjerna III. Tetrazolen (I) reagerer med trifenylmethylklorid i methylenklorid inneholdende triethylamin som base under standardbetingelser under dannelse av den beskyttede tetrazol (VII).
Propionitrilbeskyttelsesgruppen bindes som vist i reaksjonsskjema IV. Bifenylcarboxylsyren (IV) kan omdannes til syrekloridet med et utall av reagenser velkjente for fagmannen. Syreklorid-mellomproduktet reagerer med p-aminopropionitril i nærvær av en syreutvasker slik som vandig natriumhydroxyd under dannelse av amidet (VIII). Amidet (VIII) reagerer med fosforpentaklorid eller fosgen under dannelse av iminoylklorid-mellomproduktet (IX) som ved omsetning med hydrazin gir amidrazonet (X). Amidrazonet (X) reagerer lett med dinitrogentetroxyd (N2O4) som hensiktsmessig kan håndteres som en løsning i carbontetraklorid under dannelse av tetrazol (XI). Hydraziner og hydrazider er blitt vist å gjennomgå en lett omdannelse til deres tilsvarende azider med ^ 2°4 som beskrevet av Y. H. Kim et al., Tetrahedron Letters, 2_7, 4749 (1986). Den beskyttede tetrazol (XI) avbeskyttes med vandig base slik som IN NaOH, med eller uten et ytterligere organisk løs-ningsmiddel som tetrahydrofuran, under dannelse av tetrazol (I). Amidrazonet (X) kan også omdannes til tetrazolen (XI) under anvendelse av salpetersyrling eller dens ekvivalenter som beskrevet av D. G. Neilson et al., Chem. Rev., 70, 151
(1970).
Foretrukne beskyttende grupper er de hvori X<1> er Sn(R)3 og C(fenyl)3 og R er som tidligere beskrevet (reaksjonsskjema V). De ovenfor angitte grupper kan eventuelt fjernes via sur eller basisk hydrolyse, katalytisk hydro-genering og bestråling som beskrevet av Greene, Protective Groups in Organic Synthesis, Wiley-Interscience (1980).
Forbindelser av formel (I) hvori X<1> er C(fenyl)3 og X^ er Br, kan fremstilles via radikal bromering av (VII) med N-bromsuccinimid (NBS) og dibenzoylperoxyd (Bz202) under dannelse av (XII) som vist i reaksjonsskjema VI. Et eksempel på denne omdannelse er beskrevet av L. Horner et al., Angew. Chem., 71, 349 (1959.
j
Forbindelser av formel (I) hvori X<1> er C(fenyl)3 og X er I, kan fremstilles via fortrengning av bromdelen i (XII) med natriumjodid i aceton under standardbetingelser,
under dannelse av (XIII). Fortrengning av det ovenfor
i angitte bromid (XII) med hydroxydion gir den substituerte benzylalkohol (XIV). Benzylalkoholen (XIV) kan omdannes til kloridet (XV) via omsetning med carbontetraklorid og trifenylfosfin. Benzylalkoholen (XIV) kan omdannes til
tosylatet eller mesylatet (XVI) via omsetning med
) p-toluensulfonylklorid eller methansulfonylklorid i pyridin under standardbetingelser (reaksjonsskjerna VII).
Forbindelser av formel (I) hvori X<1> er C(fenyl)3 og X<2> er imidazoyl hvori R<1> er n-butyl, R<3> er Cl og R<2> er hydroxymethyl, kan fremstilles via alkylering av imidazol (XVII) med det egnede substituerte benzylhalogenid under anvendelse av natriumethoxyd som base, etterfulgt av reduksjon av formaldehyddelen på imidazolen (XVII) til hydroxymethyl med natriumborhydrid som gir (XVIII). Fremstilling av imidazolen (XVII) i reaksjonsskjerna VIII er beskrevet av Furukawa et al., i US 4.355.040.
Forbindelsene ifølge oppfinnelsen og deres fremstilling forstås ytterligere av de etterfølgende
eksempler, men skal ikke begrenses til disse. I disse eksempler er alle temperaturer i grader Celsius, og deres og prosenter er på vektbasis med mindre annet er angitt.
