Description
A találmány tárgya eljárás az (I) képletü 2-(E)-fenilmetilén-cikloheptán-l-on-(E)-oxim egyéb izomerektől mentes formában történő előállítására. Az (I) képletü vegyület értékes gyógyászati hatású származékok intermedierje, felhasználható többek között a 169 289 lsz. magyar szabadalomból ismert vegyületek szintéziséhez.The present invention relates to a process for the preparation of the 2- (E) -phenylmethylene-cycloheptan-1-one (E) -oxime of formula (I) in the free form from other isomers. The compound of formula (I) is an intermediate of valuable pharmaceutically active derivatives, which may be used, inter alia, in U.S. Pat. for the synthesis of compounds known from the Hungarian patent.
Az (I) képletü vegyület előállítására az irodalomban nem közöltek eljárást.No process for the preparation of the compound of formula (I) has been reported in the literature.
Ismeretes, hogy valamely keton egy hidroxilamin-sóból bázis jelenlétében ,,in situ” keletkező hidroxilaminnal reakcióba lép és oximot eredményez. A kiindulási keton szerkezeti sajátosságait figyelembe véve a reakció során két izomer keletkezhet. Megkülönböztetésükre egyszerűbb esetben a szín-, illetve anti-, bonyolultabb szerkezetű vegyületeknél a Z, illetve E megjelölést használjuk.It is known that a ketone reacts with hydroxylamine "in situ" formed from a hydroxylamine salt in the presence of a base to produce an oxime. Depending on the structural properties of the starting ketone, two isomers may be formed during the reaction. In their simplest case, the compounds of color and anti-complex structures are designated by the designation Z or E, respectively.
A különböző izomerek biológiai hatása tudvalevőleg különbözik egymástól, ezért van szükség ezek tisztán történő előállítására, ami csupán izomermentes intermedierekből oldható meg.The biological activity of the various isomers is known to differ from each other and it is therefore necessary to prepare them purely, which can only be solved from intermediates without isomers.
Kutatásaink során célul tűztük ki egy olyan eljárás kidolgozását, amely alkalmas a 2-(E)-fenilmetilén-cikloheptán-l-on-(E)-oxim egyéb izomerektől mentes formában történő előállítására.It has been the object of our research to develop a process for the preparation of 2- (E) -phenylmethylene-cycloheptan-1-one (E) -oxime in a form free from other isomers.
Azt tapasztaltuk, hogy ha a (II) képletü 2-(E)-fenilmetilén-cikloheptán-l-ont és/vagy vízzel korlátlanul elegyedő rövid szénláncú alifás alkoholos közegben reagáltatjuk valamilyen hidroxilamin-sóból bázis jelenlétében ,,in situ” keletkező hidroxilaminnal, majd a rekacióközeg alkoholtartalmát 40—60%-osra — előnyösen 50%-osra — állítjuk be, gyakorlatilag a kívánt (E, E)-ízomer különíthető el a reakcióelegyből. A termék legfeljebb 5%-bán tartalmaz egyéb izomereket amiktől kívánt esetben önmagukban ismert módszerekkel megtisztítható.It has been found that by reacting 2- (E) -phenylmethylene-cycloheptan-1-one of the formula (II) and / or a water-miscible lower aliphatic alcoholic medium with hydroxylamine formed in situ from a hydroxylamine salt in the presence of a base, the alcohol content of the reaction medium is adjusted to 40-60%, preferably 50%, practically the desired (E, E) isomer can be isolated from the reaction mixture. The product contains up to 5% of other isomers which may be purified by methods known per se, if desired.
A (II) képletü kiindulási vegyület ismert, és az irodalomban leírt eljárásokkal (pl. Gazz. Chim. ital. 91, 326—48 (1961) állítható elő. Hidroxilamin-sók (szulfát, hidroklorid) a kereskedelemből beszerezhetők.The starting compound of formula (II) is known and can be prepared by methods described in the literature (e.g., Gazz. Chim. Ital., 91, 326-48 (1961).) Hydroxylamine salts (sulfate, hydrochloride) are commercially available.
A 2-(E)-fenilmetilén-cikloheptán-l-on reagáltatását a hidroxilamin-sóból (célszerűen szulfátból vagy hidrokloridból) ,,in situ” keletkező hidroxilaminnal vizes és/vagy vizes alkoholos közegben végezzük. Erre a célra olyan, egyenes vagy elágazó láncú alifás alkoholok alkalmazhatók, amelyek vízzel korlátlanul elegyednek. Ilyenek pl. a metil-alkohol, etil-alkohol, n-propil-alkohol, izopropil-alkohol. Előnyösen alkohol és víz elegyében játszatjuk le a reakciót, célszerűen ezek (50—98): (2—50) részarányú elegyét alkalmazzuk. A reakció lejátszódása után víz (jég) vagy alkohol hozzáadásával állítjuk be az alkoholkoncentrációt 40—60%-ra, előnyösen kb. 50%-ra.The reaction of 2- (E) -phenylmethylene-cycloheptan-1-one with hydroxylamine "in situ" from the hydroxylamine salt (preferably sulphate or hydrochloride) is carried out in aqueous and / or aqueous alcoholic media. For this purpose, straight or branched aliphatic alcohols which are miscible with water can be used. For example, methyl alcohol, ethyl alcohol, n-propyl alcohol, isopropyl alcohol. Preferably, the reaction is carried out in a mixture of alcohol and water, preferably a mixture of (50-98): (2-50). After completion of the reaction, the alcohol concentration is adjusted to 40-60%, preferably ca. To 50%.
A reakciót bázis jelenlétében hajtjuk végre. Erre a célra szerves bázisok (piridin vagy piridin-bázisok, azaz 2,3- és 4-pikolinok keveréke, illetve lutidin) vagy szervetlen bázisok (alkálifém-hidroxidok, -karbonátok vagy -hidrogén-karbonátok) alkalmazhatók.The reaction is carried out in the presence of a base. Organic bases (pyridine or a mixture of pyridine bases, i.e. 2,3- and 4-picolines, and lutidine) or inorganic bases (alkali metal hydroxides, carbonates or bicarbonates) can be used for this purpose.
A reakcióhőmérsékletet tág intervallumban változtathatjuk anélkül, hogy ez a termelést számottevően befolyásolná. Általában 20 és 90 °C között, előnyösen 75— 85 °C között dolgozunk.The reaction temperature can be varied over a wide range without significantly affecting production. Generally, temperatures of from 20 to 90 ° C, preferably from 75 to 85 ° C, are employed.
Az előállított 2-(E)-fenilmetilén-cikloheptán-l-on (E)-oxim sztereokémiái tisztasága függ az alkalmazott 2-(E)fenilmetilén-cikloheptán-l-on sztereokémiái tisztaságától. Ha ugyanis ez utóbbi vegyületet nagyobb mennyiségű 2-(Z)-izomerje szennyezi, a lehetséges izomer-szeny2 nyezések száma megkétszereződik, és a kapott termék szennyezettsége az általunk megadott limitetet meghaladhatja.The stereochemical purity of the prepared 2- (E) -phenylmethylene-cycloheptan-1-one (E) -oxime depends on the stereochemical purity of the 2- (E) -phenylmethylene-cycloheptan-1-one used. In fact, if the latter compound is contaminated with a greater amount of its 2- (Z) -isomer, the number of possible isomeric impurities is doubled, and the impurity of the resulting product may exceed the limit given by us.
Amennyiben különlegesen tiszta termékre van szükség, akkor a reakció során keletkező nyers terméket önmagukban ismert módszerekkel (pl. oszlopkromatografálás, desztillálás, zónás olvasztás, kristályosítás petroléterből vagy etanolból) tisztíthatjuk.If a particularly pure product is required, the crude product of the reaction can be purified by methods known per se (e.g., column chromatography, distillation, zone melting, crystallization from petroleum ether or ethanol).
