Description
Fremgangsmåte til fremstilling av nye, terapeutisk aktive steroidforbindelser.
Foreliggende oppfinnelse angar en fremgangsmåte til fremstilling av nye steroidforbindelser, nemlig A g-analoge av 21-halogen-norethisteroner og deres acylater.
De forbindelser som erholdes ved fremgangsmåten ifdlge oppfinnelsen har fordelaktige oralt og parenteralt progestasjonelle egen-skaper .
Disse forbindelser er 17a-halogenethynyl-17(3-hydroxy-19-nor-4,9(IO)-androstadien-3-oner, samt acylater av disse, som tilsvarer den generelle formel:
i hvilken X betegner klor, brom eller fluor, og R betegner hydrogen eller en acylgruppe.
Ifolge oppfinnelsen fremstilles disse forbindelser ved å dehydrogenere de tilsvarende 17a-halogenethynyl-17p-hydroxy-19-nor-5(10)-androsten-3-oner som tilsvarer den generelle formel:
i hvilken X har den ovenfor angitte betydning.
Denne dehydrogenering utfores ved å behandle 17a-halogen-ethynyl-17(3-hydroxy-19-nor-5(10)-androsten-3-onet med brom i pyridin som opplosningsmiddel, hvorved der dannes den tilsvarende 5,10-di-bromforbindelse, med påfolgende dehydrobromering av denne dibromfor-bindelse. Det er ikke nodvendig å skille dibromitforbindelsen fra opp-losningsmidlet for dehydrobromeringen utfores. Det foretrekkes å an-vende pyridin som dehydrobromeringsmiddel foruten som opplosningsmiddel.
Bromeringen utfores ved en temperatur på ca. 0°C, hvorpå reaksjonsblandingen oppvarmes til ca,. 25°C for å fullstendiggjore dehydrobromeringen, eller bromerings- og dehydrobromeringsreaksjonene kan utfores samtidig ved en temperatur på ca. 25°C.
Produktet gjenvinnes fra reaksjonsblandingen ved å tilsette vann, ekstrahere med et opplosningsmiddel som ether, og fordampe opp-losningsmidlet fra ekstraktet, hvorved man får produktet i krystal-linsk tilstand.
Når det onskes å fremstille et acylat, acyleres produktet ved vanlige fremgangsmåter, som behandling med et syreanhydrid i pyridin •
Utgangsmaterialene for fremgangsmåten ifolge oppfinnelsen, f.eks. 17a-klorethynylforbindelsen, fremstilles på folgende måte: En opplosning av 1,2-diklorethylen (fortrinnsvis cisformen) tilsettes ved ca. 0°C til en opplosning av methyl-lithium, likeledes i ether. Reaksjonsblandingen omrores i nitrogenatmosfære i 1 - 2 timer, hvorved man får en opplosning inneholdende klorethyn. Til denne opplosning tilsettes 3-methoxy-19-nor-2,5(10)-androstadien-17-ol, hvorpå der omrores i flere timer. Den herved erholdte 17a-halogen-ethynyl-3-methoxy-19-nor-2, 5( IO) - andros tadien-17(3-ol omdannes til 17a-klorethynyl-17(3-hydroxy-19-nor-5 (IO) - andros ten-3-on ved omsetning med en svak organisk syre som eddiksyre. Således kan man f.eks. la en blanding av steroidet og iseddik i en vandig opplosning av abso-lutt ethanol og dioxan henstå ved romtemperatur i flere timer.
Eksempel
lOO mg 17a-klorethynyl-17p-hydroxy-19-nor-5(10)-androsten-3-on i 5 ml pyridin blev tilsatt en ekvivalent brom. Den erholdte reaksjonsblanding blev omrort i to timer ved romtemperatur, hvorpå den blev heldt i isvann, og blandingen ekstrahert med ether. Ether-ekstraktet blev vasket med vann, befridd for vann over natriumsulfat og inndampet i vakuum, hvorved man fikk 17a-klo.rethynyl-17p-hydroxy-19-nor-4,9(10)-androstadien-3-on. Smp. 151 - 152°C, a 24D -276 (kloroform), U.V. Å<Me>?<H>303 m|x, 8 19,500, infl. 235 mp., £ 5,600.
Funnet ved analyse: C 72,57 %, H 7,10 %.
Ved acyleringen av denne 17p-hydroxyforbindelse ved behandling med eddiksyre i pyridin fikk man 17a-klorethynyl-17p-hydroxy-19-nor-4,9(IO)-androstadien-3-on-acetat. Forbindelsens smeltepunkt var 144 - 145°C.
a<25>D -282 (kloroform), U.V. Å<Me>°<H>304 m\ i, £ 20,200, infl. 237 mu-,
l 5,600.
Funnet ved analyse: C 71,35 %, H 6,77 %.
