Description
A találmány tárgya eljárás a (I) képletű 10,11-epoxi-10,ll-dihidro-5H-dibenz[b,f]azepin-5-karboxamid (II) képletű 10-oxo-10,11.-dihidro-5H-dibenz[b,f]azepin-5-karboxamiddá történő átalakítására.The present invention relates to a process for the preparation of 10,11-epoxy-10,11-dihydro-5H-dibenz [b, f] azepine-5-carboxamide 10-oxo-10,11-dihydro-5H of formula (I). to convert dibenz [b, f] to azepine-5-carboxamide.
A J. Amer. Chem. Soc. 90, 4193 (1968) cikke ismerteti epoxidoknak lítiumsókkal katalizált átalakítását karbonilvegyületekké. így például ciklohexen-oxidokat vagy azok I-metil- vagy 1,2-dimetil-származékait lítium-bromiddal benzolban tri-n-butil-foszfin-oxid jelenlétében gyűrűszűkítésmellett aldehidekké vagy metil-ketonokká rendeznek át, melyek ciklopentán-származékok. Ugyancsak megemlítik, hogy az 1-metil-ciklohexen-oxid benzolban lítium-perklorát jelenlétében 80° hőmérsékleten 80%-os kitermeléssel 2-metil-ciklohexanonná rendezhető át, míg ugyanilyen körülmények között az 1,2-dimetil-ciklohexen-oxidból a 2,2-dimetil-ciklohexanon 10%-os kitermeléssel nyerhető.J. Amer. Chem. Soc. 90, 4193 (1968) describes the conversion of epoxides to carbonyl compounds by catalysis with lithium salts. For example, cyclohexene oxides or their I-methyl or 1,2-dimethyl derivatives with lithium bromide in benzene in the presence of tri-n-butylphosphine oxide are rearranged to aldehydes or methyl ketones which are cyclopentane derivatives. It is also mentioned that 1-methylcyclohexene oxide in benzene can be converted to 2-methylcyclohexanone in 80% yield in 80% yield in the presence of lithium perchlorate, while under the same conditions, 1,2-dimethylcyclohexenoxide can be converted to 2-Dimethylcyclohexanone was obtained in 10% yield.
A J. Amer. Chem. Soc. 93, 1693—1700 (1971) cikke ezenkívül ismerteti ciklohepten-oxidnak lítium-bromid és hexametil-foszforsav-triamid jelenlétében benzolban 80°-on végzett átrendezését, melynek során a cikloheptanon 26%-os kitermeléssel keletkezik. Lítium-perklorát alkalmazása esetén a cikloheptanon 17%-os kitermeléssel keletkezik. A J. Org. Chem. 34, 2355—2358 (1969) cikke szerint az exo-biciklo[4.2.O]loktén-7-oxid lítium-jodid hatására gyűrűszűkítés közben biciklo[4.1.0] heptán-7-karboxaldehiddé alakítható.J. Amer. Chem. Soc., 93, 1693-1700 (1971) also discloses the rearrangement of cycloheptene oxide in the presence of lithium bromide and hexamethylphosphoric triamide in benzene at 80 ° to give cycloheptanone in a 26% yield. produced. When lithium perchlorate is used, cycloheptanone is formed in 17% yield. J. Org. Chem. 34, 2355-2358 (1969), lithium iodide exo-bicyclo [4.2.0] can be converted to bicyclo [4.1.0] heptane-7-carboxaldehyde by ring reduction.
Az Acta Chemica Scandinavica 18, 1551—1552 (1964) cikkéből az alifás epoxidok metil-jodiddal és nátrium-jodiddal dimetil-formamidban 4 órás viszszafolyatás közben végzett izomerizálása ismeretes, melynek során a megfelelő keton kvantitatív kitermeléssel keletkezik. A Chem. Comm. 1968 227—229oldalaindimetil-szulfoxidban oldott epoxiciklohexán izomerizációját ismerteti, nátrium-jodiddal, és n-propiljodiddal, melynek során 90%-os kitermeléssel ciklo-hexanon keletkezik. E két utóbbi eljárást az (I) képletű vegyidet esetén alkalmazva az első esetben a vékonyrétegkromatográfiás vizsgálat szerint (szilikagél-lemezek, futtatószer etil-acetát) olyan termék keletkezett, mely a (II) képletű vegyületnek csak nyomnyi mennyiségét tartalmazta, míg a második esetben a megfelelő végtermék egyáltalán nem volt kimutatható. Megállapítottuk azt is, hogy ha a fentiekben ismertetett eljárást alkalmaztuk az (I) képletű vegyület esetén, mely szerint 1-metil-ciklohexen-oxidot benzolban lítium-perklorát jelenlétében alakítottak 2-metil-ciklohexanonná, olyan termék keletkezett, mely szilikagél-lemezeken etil-acetát futtatószert használva vékonyrétegkromatográfiásan csak a (II) képletű vegyület nyomnyi mennyiségét mutatta.Acta Chemica Scandinavica 18, 1551-1552 (1964) discloses isomerization of aliphatic epoxides with methyl iodide and sodium iodide in dimethylformamide for 4 hours to give the corresponding ketone in quantitative yield. Chem. Comm. 1968 discloses the isomerization of epoxycyclohexane in 227-229 pages of dimethylsulfoxide, with sodium iodide and n-propyl iodide to give cyclohexanone in 90% yield. Applying the latter two methods to the compound of formula (I) in the first case by thin layer chromatography (silica gel plates, ethyl acetate as eluent) yielded a product containing only trace amounts of the compound of formula (II). no suitable end product could be detected at all. It was also found that using the above procedure for the compound of formula (I) to convert 1-methylcyclohexene oxide in benzene to 2-methylcyclohexanone in the presence of lithium perchlorate, the product formed on silica gel plates with ethyl TLC showed only trace amounts of the compound of formula (II).
Meglepő módon úgy találtuk, hogy a 10,11-epoxi-10,1 l-dihidro-5H-dibenz [b,f ]azepin-5-karboxamid 10-oxo-10,ll-dihidro-5H-dibenz[b,f]-azepin-5karboxamiddá történő átalakítása a lítium, magnézium vagy kalcium bromidja vagy jodidja alkalmazásával végrehajtható anélkül, hogy szükség volna metil-jodid vagy η-ρτορίΐ-jodid hozzáadására. Az eljárás során előnyös a fenti fémek jodidjának alkalmazása. Az alkalmazott sók képlete ezek szerint az LiBr, Lil, MgBr2, Mgl2 CaBr2 és Cal2.Surprisingly, it has been found that 10,11-epoxy-10,11-dihydro-5H-dibenz [b, f] azepine-5-carboxamide 10-oxo-10,11-dihydro-5H-dibenz [b, f] conversion of] -azepine-5-carboxamide to bromide or iodide of lithium, magnesium or calcium without the need for the addition of methyl iodide or η-ρτορίΐ-iodide. In the process, the use of iodide of the above metals is preferred. The salts used are thus defined as LiBr, Lil, MgBr 2 , Mgl 2 CaBr 2 and Cal 2 .
E sókat vízmentes formában vagy önmagában ismert, vízzel (hidrátok) vagy dietil-éterrel (dietiléterát) alkotott formájukban használhatjuk.These salts may be used in anhydrous form or in their known form with water (hydrates) or diethyl ether (diethyl etherate).
A hidrátok például a következők: LiBr-H2O, LiBr -2H2O, LiBr-3H2O, LiI H20, LiI 2H2O,LiI• 3H2O, MgBr2 · 6H2O, MgBr2 10H2O, Mgla · 8H2O, Mgl2 · 10H2O, CaBr2 -6H2O, Cal2 -4H2O, Cal2 ·6Η2Ο.Examples of hydrates are: LiBr-H 2 O, LiBr- 2 H 2 O, LiBr-3 H 2 O, Li I H 2 O, Li I 2 H 2 O, Li I • 3 H 2 O, MgBr 2 · 6H 2 O, MgBr 2 10H 2 O, Mgl a · 8H 2 O, Mgl 2 · 10H 2 O, CaBr 2 -6H 2 O, Cal 2 -4H 2 O, Cal 2 · 6Η 2 Ο.
A találmány szerinti eljárás során előnyösen alkalmazható sók, ezek hidrátjai illetve dietil-éterátjai a következők: LiBr, LiI-2H2O, Mgl2-(dietil-éterát) és CaI2-4H2O.The preferred salts, hydrates and diethyl ethers of the process according to the invention are LiBr, LiI-2H 2 O, Mgl 2 - (diethyl etherate) and Ca 2 4 -4H 2 O.
A találmány szerinti reakciót valamely oldószerben, például egy adott esetben halogénezett alifás vagy aromás szénhidrogénben, például valamely halogén-, például klór-alkánban, például metilén-kloridban, szén-tetrakloridban, etilén-kloridban v. difluor-klór-metánban, előnyösen azonban kloroformban végezzük. Aromás jellegű oldószer például a benzol vagy klór-benzol. Előnyös lehet egy további oldószer adagolása, hogy elősegítsük a lenti sóknak az alkalmazott oldószerben való oldódását. Ilyen szempontból elsősorban poláros oldószerek jönnek számításba, például a tetrahidrofurán, dioxán, vagy egy foszforamid-származék, például hexametil-foszforsav-triamid. Az alkalmazandó poláros oldószer mennyisége az alkalmazott só minőségétől függ, általában az adalék felső határa 1 mól oldószer 1 mól sóra vonatkoztatva.The reaction of the invention is carried out in a solvent such as an optionally halogenated aliphatic or aromatic hydrocarbon such as a halogen such as chloroalkane such as methylene chloride, carbon tetrachloride, ethylene chloride or the like. in difluorochloromethane, but preferably in chloroform. An aromatic solvent is, for example, benzene or chlorobenzene. It may be advantageous to add an additional solvent to facilitate the dissolution of the salts below in the solvent used. Polar solvents, for example, tetrahydrofuran, dioxane, or a phosphoramide derivative such as hexamethylphosphoric triamide, are preferred. The amount of polar solvent to be used will depend on the nature of the salt used, usually with an upper limit of 1 mole of solvent per mole of salt.
