Description
2,2-d.isubstituirani 1,3-dioksolani kot antitusične učinkovine
Predmet pričujočega izuma so (±) 3-(4-fenil-lpiperazinil)-1,2-propandiol ciklični acetali oz. njihove soli, postopek za njihovo optično ločevanje ter njihova uporaba kot vmesnih spojin za pripravo (-) 3-(4-fenil-lpiperazinil)-1,2-propandiola (levodropropizina).
Natančneje, predmet izuma so (±) 2,2-substituirani1,3-dioksolani po formuli (1):
kjer:
sta lahko Ra in Rb bodisi enaka ali različna, in sicer sta vodik, Ci-Cg-alkil, fenil ali pa
Ra in Rb, vzeta skupaj s C atomom, na katerega sta vezana, tvorita fakultativno substituiran 4- do 7-členi karbociklični obroč.
V spojinah s formulo (1) po izumu sta Ra in Rb prednostno alkilni skupini, vsebujoči manj kot 6 C atomov. Ra in Rb sta prednostno enaka; posebno prednostno sta Ra in Rb metil ali etil oz., vzeta skupaj s C atomom, na katerega sta vezana, tvorita obroč, vsebujoč od 5 do 6 ogljikovih atomov.
Predmet izuma so tudi enantiomerno čiste enobazne soli
2,2-substituiranih-l,3-dioksolanov s formulo (1) in farmacevtsko sprejemljivih kiralnih kislin, kot so Ljabolčna, D- in L-vinska, D- in L-mandl j eva, L- in Dkamforsulfonska kislina.
Primeri posebno prednostnih spojin po izumu so:
(±) 1,2-ciklopentiliden-3-(4-fenilpiperazin-l-il)propan-1,2-diol;
(±) 1,2-cikloheksiliden-3-(4-fenilpiperazin-l-il)propan-1,2-diol;
(±) 1,2-(2-propiliden)-3-(4-fenilpiperazin-l-il)propan-1,2-diol;
(±) 1,2-(3-pentiliden)-3-(4-fenilpiperazin-l-il)propan-1,2-diol;
S(-)-1,2-cikloheksiliden-3-(4-fenilpiperazin-l-il)propan-1,2-diol L-tartrat;
S(-)-1,2-ciklopentiliden-3-(4-fenilpiperazin-l-il)propan-1,2-diol L-tartrat.
Spojine s formulo (1) po izumu se pripravijo z reakcijo med fenilpiperazinom in (+) 1,2glicerildioksolanom s formulo (2):
kjer je X izbran iz skupine, ki vključuje Cl, Br, I in primeren sulfonski ester (R-SO3-) , medtem ko je R izbran iz skupine, ki vključuje Ci-C3-alkil (prednostno metil), trifluormetil, fenil, p-tolil in p-metoksifenil.
Dioksolani s formulo (2) so poznane spojine oz. jih je moč pripraviti po poznanih postopkih.
Sulfonski estri po formuli (2) (X= R-SO3-) se pripravijo tako, da se anhidrid ali klorid alkil- oz. arilsulfonske kisline s formulo (3)
R-SO3H (3) uporabi za estrenje (±) 2,2-substituiranega-l,3dioksolan-4-metanola s formulo (4):
kjer sta Ra in Rb taka, kot je bilo zgoraj opredeljeno.
Spojine s formulo (4) so poznane. Racemati s formulo (4) se celo uporabljajo kot substrati za fermentacijske ločevalne postopke [US Pat. 5.190.8,67 (02.03.1993)].
Priprava dl-izopropilidenglicerola (Merck 12.5232; Beil 19.65) iz glicerola je opisana v III. zvezku Org. Synth. Coli.
4-halometildioksolani po formuli (2), v kateri je X Cl, Br ali I, se lahko pripravijo iz ustreznih sulfonatov s formulo (2) (X = RSO3-, kjer je R tak, kot je bilo zgoraj opredeljeno) z reakcijo s halidom alkalije ali zemeljske alkalije v inertnem topilu, izbranem iz skupine, ki vključuje aceton, metiletilketon, tetrahidrofuran, dioksan, dimetilsulfoksid, acetonitril, C1-C4-alkohol in njihove mešanice. Prednostna metoda za sintezo navedenih spojin vključuje dioksolaniranje ustreznih 3-halo-l,2propandiolov, kot je podano v patentu EP 0930311 (21.07.1999). Posebno prednosten pri tem je 3-klorpropan1,2-diol; prednostni acetalizacijski agensi so formaldehid, acetaldehid in benzaldehid, aceton, dietilketon, benzofenon, cikloheksanon ter njihovi acetali oz. enoletri, kot so npr. 2,2-dimetoksipropan, 2,2-dimetoksietan, 2metoksipropen.
Alternativno je moč dioksolane po formuli (2) (X - Cl ali Br) pridobiti tudi z acetaliziranjem epikiorhidrinov ali epibromhidrinov s cikloalkanonom po postopkih, opisanih za pripravo (+) 2-klormetil-l,4-dioksaspiro[4,5]-dekana v patentu FR 1522153 ali v besedilih FF Blickeja in sodelavcev, objavljenih v J. A. C. S., 74, 1735 (1972) in prav tam, 76, 1226 (1954).
Alkiliranje fenilpiperazina z 1,2-glicerildioksolanom po formuli (2) se izvaja v reakcijskih pogojih, ki se običajno uporabljajo za konverzijo sekundarnega amina v terciarnega, pri čemer se za vsak mol alkilacijskega agensa po formuli (2) uporabi najmanj en mol· ali neznaten molski prebitek fenilpiperazina v prisotnosti najmanj enega mola protibaze. Protibaza se uporabi v vsaj enakovrednih molskih količinah kot alkilacijski agens po formuli (2), izbere pa se iz skupine, ki vključuje fino ločene anorganske baze, kot so npr. karbonati oz. bikarbonati alkalij ali zemeljskih alkalij (Na, K, Mg, Ca) ali Ca oz. Mg oksidi ali terciarni amini, kot so trietilamin, dimetil- ali dietilanilin, aromatski amini, kot so piridin, pikolin in kolidin ter po želji tudi sam fenilpiperazin, ki ga je moč zatem reciklirati za naslednji proizvodni cikel·.
Alkiliranje se lahko izvaja s segrevanjem, po želji v prisotnosti inertnih topil, kot sta toluen ali ksilen, ki ugodno skrajšata reakcijske čase, ko delujeta pri vreliščni temperaturi topila.
Po zaključenem alkiliranju se morebitne netopne snovi odstranijo s filtriranjem ali centrifugiranjem, nakar se organske faze večkrat sperejo z vodo, s čimer se zlahka odstranijo nečistoče in stranski produkti, topilo pa se odstrani z destiliranjem, kar nam z visokimi izkoristki da ostanek, ki sestoji iz v bistvu čistega 1,3-dioksolana s formulo (1) po izumu, katerega dobimo bodisi z neposredno kristalizacijo ali pa po nevtralizaciji z molskim ekvivalentom karboksilne kisline.
Spojine (1) in njihove soli s presenetljivo lahkoto
-•A· kristalizirajo iz običajnih topil: zato postopek po izumu skrajno zmanjša tveganje, da bi prišlo do kontaminacij e zaradi prisotnosti sledov glicidolov in/ali epihalohidrinov kot potencialnih nečistoč.
Enobazne soli spojin po formuli (1) se pridobivajo z uporabo poznanih metod, kot so nevtralizacija z ekvimolekularnimi količinami želene kisline v primernem topilu, ki ji sledi kristalizacija dobljene soli.
Kot se je izkazalo, predstavlja nevtralizacija spojin (1) s kiralnimi kislinami, zlasti z L-vinsko kislino, učinkovito optično ločevalno metodo za pridobivanje Senantiomerov spojin (1) z visokimi izkoristki.
Navedeni (S) (-) enantiomeri in njihove soli so uporabni kot antitusične učinkovine ali kot vmesne spojine za sintezo (-) 3-(4-fenil-l-piperazinil)-1,2-propandiola (levodropropizina) z vročo hidrolizo vodnih raztopin (-)
1,3-dioksolanov po formuli (1), katalizirano z molskim prebitkom razredčene vodne raztopine mineralne, npr. solne kisline, ali karboksilne kisline, kot so ocetna, malonska ali citronska kislina.
Spodaj navedeni primeri podrobneje ilustrirajo izum.
1. primer
V raztopino 11,98 g (±) 2,3-0-(3-pentiliden)-glicerol tosilata v n-butanolu (70 ml) se med močnim mešanjem doda 4,5 g fino ločenega natrijevega karbonata, zatem pa še 6 ml fenilpiperazina. Mešanica se med vrenjem meša in pusti reagirati 20 h pri temperaturi vrelišča. Butanol se nato odpari pri zmanjšanem tlaku, ostanek pa se razredči z vodo in večkrat ekstrahira z etilacetatom. Kombinirani organski fazi se posušita in prefiltrirata, nakar se topilo odpari v vakuumu, dobljeni ostanek pa se kristalizira iz vodne raztopine metanola, kar nam da 8,95 g (±) 1,2-(3pentiliden)-3-(4-fenilpiperazin-l-il)-propan-1,2-diola, znanega tudi pod imenom 4-fenilpiperazin, 1-(2,2-dietil1,3-dioksolan-4-il-metil).
2. primer
Po postopku, opisanem v 1. primeru, se iz (±) 2,3-0(2-propiliden)-glicerol tosilata dobi (±) 1,2-(2propiliden)-3-(4-fenilpiperazin-l-il)-propan-1,2-diol, znan tudi pod imenom 4-fenilpiperazin, 1-(2,2-dimetil-l,3dioksolan-4-il-metil).
3. primer
Raztopini 3,28 g (±) 1,4-dioksaspiro-[4.5]dekan-2metilklorida v toluenu (16 ml) se v inertni plinski atmosferi doda 5,45 ml fenilpiperazina. Mešanica zatem vre, dokler se reakcija ne zaključi (približno 8 ur). Reakcijska mešanica se ohladi na okrog 50° C, nakar se vanjo doda 10 ml vode in se vsaj 10 minut močno meša. Fazi se ločita in organska faza se večkrat spere z vodo. Topilo se odpari, da nastane gosto olje, to pa se raztopi v vročem izopropanolu (15 ml). Izhodna raztopina se počasi ohladi, da se izloči (±) 1,2-cikloheksiliden-3-(4-fenilpiperazin-l-il)-propan1.2- diol kot kristalna trdnina s tališčem pri 58-61° C.

Vodna faza se z dodajanjem 10-odstotne raztopine NaOH nevtralizira na pH 7,5, nato pa se ohladi na 5-10° C, kar nam da 1,97 g (-) 3-(4-fenilpiperazin-l-il)-propandiola, tališče 102-103° C, [α]D=-23,5° (2,8% CH2C12) .

Dvofazno mešanico vremo, da se z destiliranj em izloči vodni n-butanol azeotrop, kar nam da okrog 300 ml destilata, ki se nato ohladi, da se spodbudi kristalizacija (-) 3—(4— fenilpiperazin-l-il)-propandiol hidroklorida (85 g).

Po krajšem segrevanju na 50° C se z dodajanjem kristalov (-) 3-(4-fenilpiperazin-l-il)-propandiola sproži kristalizacija. Počaka se, da se suspenzija sama od sebe ohladi, nakar se drži 2 uri pri +2 do +4° C, nazadnje pa se prefiltrira, pri čemer se dobi 70-72 g (-) 3-(4fenilpiperazin-1-il)-1,2-propandiola .
