DK 170233 B1 i
Den foreliggende opfindelse angår en hidtil ukendt fremgangsmåde til fremstilling af alkoxymethylethere og alkoxymethylestere af glyceroler. Nærmere betegnet angår den foreliggende opfindelse en fremgangsmåde til fremstilling af mellemprodukter til anvendelse ved frem-5 stillingen ifølge stamansøgningen (ansøgning nr. 5740/85) af 9-(1,3-dihydroxy-2-propoxymethyl)guanin samt estere og ethere deraf.
9-(l,3-dihydroxy-2-propoxymethyl)guanin (i det følgende benævnt DHPG) samt estere deraf er kraftigt antivirale midler, og har være fremstillet ved fremgangsmåder omhandlet i US patentskrift nr. 4.355.032 og 10 europæiske patentansøgninger nr. 49.072, 72.027 og 74.306. Tilsvarende forbindelser med lignende sidekæder omhandles i US patentskrifter nr. 4.347.360 og 4.199.574.
Ved fremgangsmåden ifølge opfindelsen fremstilles hidtil ukendte DHPG-ether- eller -estersidekædemellemprodukter i færre trin end ved 15 andre for tiden anvendte fremgangsmåder under frembringelse af færre uønskede biprodukter.
Sidekædemellemprodukterne til fremstilling af DHPG og estere og ethere deraf har hidtil været fremstillet ved at omsætte epichlorhydrin med en benzyl al kohol til opnåelse af en symmetrisk substitueret 1,3-20 di benzyl glycerol, som derpå chlormethyleres. Chlormethylforbindel sen omdannes til eddikesyre- eller myresyreesteren, der så kobles til guanin i 9-stillingen deraf. Se US patentskrift nr. 4.355.032.
En alternativ syntese omhandles i US patentskrift nr. 4.347.360, hvor l,3-dichlor-2-propanol omsættes med natriumbenzylat til dannelse af 25 chlormethoxyderivatet, som yderligere omsættes med en purinbase.
En tredie metode omhandles i europæisk patentansøgning nr. 74.306. Ifølge denne ansøgning fremstilles sidekæden ud fra glycerol formal, en blanding af l,3-dioxan-5-ol og l,3-dioxolan-4-methanol. Nævnte glycerolformal acyleres og blandingen separeres. Den acylerede forbindelse om-30 sættes så med eddikesyreanhydrid i nærværelse af ZnClg til dannelse af en forbindelse, som kan omsættes med en purin.
Disse synteser er alle flertrinsmetoder, som medfører komplicerede separations- og rensningsmetoder.

Nedennævnte udtryk har i det foreliggende, med mindre andet er an 5 ført, følgende betydninger.
6 "Lavere alkyl" betegner enhver uforgrenet eller forgrenet carbon- DK 170233 B1 4 hydridgruppe med 1-4 carbonatomer f.eks. methyl, ethyl, propyl, i-propyl, butyl, t-butyl og lignende.
"Eventuelt substitueret" henfører til substituenter i form af halogen, lavere al kyl eller phenyl på al kyl- eller phenyl grupper.
5 "Acyl" betegner eventuelt substitueret alkyl-C(O) indeholdende 4-20 carbonatomer i al kyl kæden, eventuelt substitueret phenyl-C(0) eller % eventuelt substitueret alkyl- phenyl-C(0), hvor nævnte substituenter er bundet til phenylringen. Eksempler omfatter n-hexanoyl, n-heptanoyl, palmitoyl, steracanoyl, arachidoyl, pivaloyl, 1-methyl-1-cyclohexan- 10 carboxoyl, 2-octyl-decanoyl, benzoyl, p-chlorbenzoyl, toluoyl, phenyl -acetyl, 3-phenylpropanoyl og 4-phenylbutanoyl.
"Pivalinsyre" er 2,2-dimethylpropionsyre.
"1-adamantanoyl" betegner gruppen med den nedenfor anførte strukturformel 15 t*° Λ 20 1-adamantanoyl
Phenyl er en seks-ledet carbonring som indeholder 3 dobbeltbindin ger.
25 Alkylphenyl betegner en phenylgruppe, hvortil er bundet en substituent i form af en al kyl kæde, hvor al kyl har den ovenfor angivne betydning.
"Hydrogendonor" betegner ethvert stof, som kan tjene som kilde for aktivt hydrogen. Eksempler på hydrogendonorer er gasformigt hydrogen, 30 cyclohexen, 1,4-cyclohexadien og lignende. I nogle tilfælde kan katalysatorer anvendes sammen med hydrogendonorer, således kan f.eks. ædelmetaller, såsom platin, palladium og rhodium, anvendes på findelt metallisk form eller som metal på en konventionel katalysatorbærer, f.eks.
carbon, aluminiumoxid eller siliciumoxid.
7 » 35 "Syre" vil i det foreliggende normalt være en specifikt benævnt syre, såsom pivalinsyre, eller vil være benævnt som protonsyre eller Lewis-syre.
"Lewis-syre" betegner enhver syre, som ikke indeholder en fraspal- 5 DK 170233 B1 tel ig proton. Som eksempler kan nævnes Be(CH3)2, BF,, B(0-alkyl)3, A1(CH3), A1(C1)3> Fe3+, Mg2+, Ca2+, Cu+, TiCl,, HgZi, Co2+, Fe2+, Zn2+ og så videre. En udtømmende opregning af Lewis-syrer kan findes i Chem. Rev., 75, 1, (1975) på side 2.
5 "Protonsyre" betegner enhver Brønsted-syre med en pK -værdi på mindre end 2,0 og fortrinsvis mindre end 1,0 og indeholdende en fraspaltelig proton.

Formel A ° fHOR1 r—ccr^o—c diHOR3 1 3 7 DK 170233 B1 hvor R og R er udvalgt fra gruppen bestående af hydrogen eventuelt substitueret med lavere alkyl, 1-adamantanoyl, acyl, eventuelt substitueret phenyl eller eventuelt substitueret phenyl-lavere al kyl, og R7 er R4C(0)0CH2 eller R6OCH2, hvor R4 og R6 uafhængigt er valgt blandt even-5 tuelt substitueret lavere al kyl.
I reaktionssekvens A omsættes en dialkyloxymethan med formel F med et anhydrid med formel G i nærvær af en protonsyrekatalysator. De to reaktanter er til stede i et ca. ækvimolært forhold i nærvær af en katalytisk mængde af en protonsyre, f.eks. organiske sulfonsyrer, såsom 10 para-toluensulfonsyre, eller katalytiske mængder af en mineralsyre, f.eks. saltsyre eller svovlsyre. Omsætningen kan udføres i et aprot carbonhydridopløsningsmiddel, f.eks. benzen, eller uden opløsningsmiddel typisk ved opløsningens tilbagesvalingstemperatur. Opløsningen omsættes i 1 til 12 timer, idet ca. 6 timer er typisk. Der henvises til frem-15 gangsmåden i J. Am. Cem. Soc., 76, side 5161 (1954).
Det foretrækkes, at anhydrid og dialkyloxymethan er symmetriske fordi antallet af mulige produkter reduceres dramatisk ved anvendelse af symmetriske reagenser. Asymmetriske anhydrider eller asymmetriske al kyl-oxymethaner kan naturligvis omsættes ved fremgangsmåden ifølge opfindel-20 sen. I visse tilfælde kan asymmetriske anhydrider være selektive ved fremstilling af et af de mulige produkter.
1,3-dialkanoylglycerolen med formel E kan fremstilles ad to veje. Behandling af glycerol med lidt mere end to ækvivalenter syrechlorid eller syreanhydrid i aprote opløsningsmidler i nærvær af organisk base, 25 f.eks. tri al kyl aminer, og en nukleofil katalysator, f.eks. pyridin kan give 1,3-dialkanoylglycerol med formel E.
Alternativt kan disse forbindelser opnås ud fra dihydroxyacetoner under anvendelse af den i J. Org. Chem., 35, 2082, (1970) omhandlede fremgangsmåde. Behandling af dihydroxyacetone i pyridin med en ækviva-30 lent af det hensigtsmæssige fede syrechlorid fulgt af reduktion af den centrale ketogruppe med borhydrid i tetrahydrofuran kan give 1,3-di-alkanoylglycerol med formel E.
I reaktionssekvens B omsættes forbindelsen med formel D med forbindelsen med formel E i nærvær af en protonsyrekatalysator, f.eks. orga-35 niske sulfonsyrer, såsom para-toluensulfonsyre, eller katalytiske mængder af en mineral syre, f.eks. saltsyre eller svovlsyre, til dannelse af en blanding (formel C), Denne blanding er sammensat af forbindelsen med formel A og forbindelsen med formel C'. Forbindelser med formel D og 8 DK 170233 B1 formel E blandes i fravær af opløsningsmiddel med en katalytisk mængde af en protonsyrekatalysator. Det foretrækkes, at anvende et overskud af forbindelsen med formel D, idet overskuddet er nyttigt som opløsningsmiddel ved omsætningen. Reaktanterne kan sammenblandes uden behov for 5 ekstern opvarmning, skønt anvendelse af opvarmning vil forøge reaktionshastigheden. Reaktion B kan være eksoterm, og når temperaturen falder til omgivel sestemperatur er reaktionen afsluttet. Det tager mellem 1 og ’ 6 timer, typisk ca. 2 timer, før omsætningen er løbet til ende.
Blandingen (formel C) varierer i afhængighed af udgangsmaterialer- 10 ne. Hvis f.eks. R og R er benzyl giver reaktionssekvens B hovedsaglig 1 3 en forbindelse med formel A, men hvis R og R er pivaloyl giver reaktionssekvens B hovedsaglig en forbindelse med formel C7. Reaktionssekvens C kan udelades, hvis produktet fra reaktionssekvens B er en forbindelse med formel A. Ellers omsættes forbindelserne i overensstemmel-15 se med reaktionssekvens C.
I reaktionssekvens C omsættes blandingen af forbindelser med formel C derpå yderligere i nærvær af et alkylanhydrid og en Lewis-syrekatalysator. Det foretrækkes, at det ved omsætningen anvendte anhydrid er et symmetrisk anhydrid for at reducere det mulige antal dannede produkter, 20 skønt dette ikke er et krav til omsætningen.
Den katalytiske syre er fortrinsvis en ikke-proton afgivende Lewis-syrekatalysator, f.eks. bortrifluorid eller aluminiumtrichlorid. Reaktionstemperaturen stiger fra omgivelsestemperatur til ca. 50°C, på hvilket punkt temperaturkontrol bringes i anvendelse. Reaktionstemperaturen 25 haldes i almindelighed mellem ca. 45°C og 65°C, fortrinsvis imellem ca.
50°C og ca. 60°C.
Reaktionsforløbet følges typisk ved tyndt!agskromatografi (TLC) for at angive i hvilket omfang reaktionen er løbet til ende. Efter imellem 60 og 180 minutter vil omsætningen normalt være løbet til ende. Reak-30 ti onsblandingen ekstraheres med et organisk opløsningsmiddel som vaskes med natriumcarbonat og vand. Det organiske lag tørres så og produktet med formel A opnås ved afdampning af opløsningsmidlet. ;
Opfindelsen belyses nærmere ved eksempler.
