Description

Analogifremgangsmåte til fremstilling av Analogy method for the production of

terapeutisk virksomme steroid-oksazolidinoksaziner. therapeutically active steroid oxazolidine oxazines.

Foreliggende oppfinnelse vedrører en analogifremgangsmåte til fremstilling av terapeutisk virksomme steroid-oksazolidinoksaziner med den generelle -formel: hvor R, som kan være like eller forskjellige, er hydrogen eller metyl og denne fremgangsmåte er kjennetegnet ved at en steroid-oksazolidin med den generelle, formel: The present invention relates to an analogous process for the production of therapeutically effective steroid-oxazolidine oxazines with the general formula: where R, which may be the same or different, is hydrogen or methyl and this process is characterized by the fact that a steroid-oxazolidine with the general formula:

hvor R har den ovenfor angitte betydning, omsettes med en karbonyl-forbindelse med den generelle formel RCOR, hvor R har den ovenfor angitte betydning, eller et funksjonelt derivat derav, ved en temperatur på mellom 0°C og karbonylforbindelsens éller dens funksjonelle derivats kokepunkttempera'tur. where R has the meaning given above, is reacted with a carbonyl compound of the general formula RCOR, where R has the meaning given above, or a functional derivative thereof, at a temperature between 0°C and the boiling point temperature of the carbonyl compound or its functional derivative' trip.

De fremstilte, hittil ukjente forbindelser som har terapeutisk virkning, har spesielt en meget sterk betennelseshemmende virkning. The manufactured, hitherto unknown compounds which have a therapeutic effect, in particular have a very strong anti-inflammatory effect.

Kondensasjonen mellom steroid-oksazolidinet og karbonyl-forbindelsen RCOR, hvor R har den angitte betydning, eller et funksjonelt derivat av karbonylgruppen, slik som et acetal, kan utføres i nærvær av vann eller under vannfrie betingelser. . Cyklopentanringen D i steroidet har, som det fremgår fra formlene, en temmelig fastlagt struktur, mens strukturen til de andre tre ringer i steroidet kan variere i utstrakt grad. F.eks. kan det være en eller flere dobbeltbindinger i stillingene 1, ^, 6, 9, (11). OksygenhoIdige grupper slik som en ketongruppe eller en hydroksygruppe kan wære tilstede i stillingene 3 og 11 eller i begge stillinger. Det er også mulig å utføre de ovenfor angitte reaksjoner på steroider med en 9~halogensubstituent. The condensation between the steroid oxazolidine and the carbonyl compound RCOR, where R has the stated meaning, or a functional derivative of the carbonyl group, such as an acetal, can be carried out in the presence of water or under anhydrous conditions. . The cyclopentane ring D in the steroid has, as can be seen from the formulas, a rather fixed structure, while the structure of the other three rings in the steroid can vary widely. E.g. there may be one or more double bonds in positions 1, ^, 6, 9, (11). Oxygen-containing groups such as a ketone group or a hydroxy group may be present in positions 3 and 11 or in both positions. It is also possible to carry out the above-mentioned reactions on steroids with a 9-halogen substituent.

Praktisk talt alle forbindelser som er omfattet av følgende formel-har betennelseshemmende virkning: Practically all compounds covered by the following formula have an anti-inflammatory effect:

hvor R, som er like eller forskjellige, er hydrogen, en lavere alkylgruppe eller arylgruppe, og som kan ha en eller to oksygen-holdige grupper i stillingene 3 og 11 eller i begge stillinger, et halogenatom kan være tilstede i stilling 9, og det kan forefinnes where R, which are the same or different, is hydrogen, a lower alkyl group or an aryl group, and which may have one or two oxygen-containing groups in positions 3 and 11 or in both positions, a halogen atom may be present in position 9, and the can be found
