  Verfahren     zur    Herstellung von Estern von     (-)-3-Hydroxy-morphinanen       Die Erfindung betrifft. ein Verfahren zur       lIer;stelhing    von Estern des     (-)-3-Hyclroxy-          morphinans,    welche am Stickstoff einen gesät  tigten oder     ungesättigten        Alkyl-Substituenten     von     mindestens    3     Fohlenstoffatomen    tragen.  Diese Verbindungen besitzen wertvolle biolo  gische     Eigenschaften;    sie vermögen in kleinen  Dosen die     uner ,ünschten    Nebenwirkungen,  z.

   B. die     atemlähmende    und     diuresehemmende     Wirkung des Morphins und ähnlich wirkender  Pharmaka rasch     aufzuheben    und sind daher  als Arzneimittel von     Interesse.     



  Nach dem     erfindungsgemässen    Verfahren  erhält man. die neuen Verbindungen, indem  man ein am     qtiel-:stoffatoinidurch    einen     eesättig-          ten    oder     ungesättigten,        mindestens    3     Kohlen-          stoffatome    enthaltenden     Alkvlrest    substituier  tes     (-)-3-IIyclroxy-morphinan        verestert.    Das  am Stickstoffatom substituierte     (-)-3-Hydr-          oxy-morpliinan,    z.

   B.     (-)-3-II@#droxy-N-allyl-,          -N-propargyl-,    -N     metlial.lyl-,        -N-erotyl-,    -N  propyl-, oder     .\-isohtttyl-morphinan    kann mit.  einem     Säureanhydrid    oder     Säurehalogenid,     wie z. B.     Essigsäure-,        Propionsäure-anhyd-rid     oder     Penzo:#1-ehlorid,    behandelt werden.

   Auf  diese Weise erhält man die     Aeetyl-,        Propionyl-          bzw.        Benzoyl-Verbindungen    der     (-)-3-Hydr-          oxv-N-allyl-,        -propargv'l-,        -metha:llyl-,        -erotyl-,          -propy    l- bzw.     -isobuty        l-morphinane.

   die     N-Propyl-    und     N-Isobtityl-Verbin-          dungen    können auch .aus der     N-Allyl-    bzw.     N-          3Tethally1-Verbindrzng    durch     katalytische    Hy  drierung gewonnen werden.  



       Beispiel   <I>1</I>  30 g     (-)-3-Hydroxy-N-allyl-morphinan     werden mit 150     cm3        Essigsäure-anhydrid    4  Stunden auf 80  C erwärmt. Die Reaktions  lösung wird im Vakuum eingedampft, der,  Rückstand in Benzol gelöst und mit eiskalter       n-Sodalösung    und Eiswasser gewaschen.

   Die  mit.     Natriumsulfat    getrocknete     Benzollösung     wird im     Vakuum    eingedampft und das     (-)-          3-Acetoxy-N-a.llyl-morphinan    im     Hochvakuum          destilliert..    Siedepunkt bei 0,001 mm     Hg156     C.  Das     Hydrobromid,    aus     Butwlaeetat    kristalli  siert, schmilzt bei 212-214  C und zeigt eine  Drehung von     [a]D    = -41,4  (c = 3 in Fein  sprit).  



       Beispiel   <I>2</I>  50 g     (-)-3-Hydroxy-N-allyl-morphinan     werden in 500     cma    Aceton suspendiert und  unter Rühren bei 25-30  C mit. 30     cm3        Ben-          zoylchl.orid        versetzt.    Das     (-)-3-Hydroxy-N-          allyl-morphinan    geht rasch in     Lösung    und  nach kurzer Zeit     kristallisiert    das     (-)-3-Ben-          zoyloxy-N-allyl-morphinän-hydrochlorid    aus.

  Process for the preparation of esters of (-) - 3-hydroxy-morphinans The invention relates to. a process for the production of esters of (-) - 3-Hyclroxy- morphinans, which carry a saturated or unsaturated alkyl substituent of at least 3 foal atoms on the nitrogen. These compounds have valuable biological properties; In small doses they can have undesirable side effects, e.g.

   B. the respiratory paralyzing and diuresis-inhibiting effects of morphine and drugs with a similar effect quickly and are therefore of interest as drugs.



  The process according to the invention gives. the new compounds by esterifying a (-) - 3-hydroxy-morphinan which is substituted on the qtiel-: stoffatoinid by an unsaturated or unsaturated alkyl radical containing at least 3 carbon atoms. The substituted on the nitrogen atom (-) - 3-Hydro- oxy-morpliinan, z.

   B. (-) - 3-II @ # droxy-N-allyl-, -N-propargyl-, -N metlial.lyl-, -N-erotyl-, -N propyl-, or. \ - isohtttyl-morphinan can With. an acid anhydride or acid halide, such as. B. acetic acid, propionic acid anhydride or penzo: # 1-ehlorid treated.

   In this way, the ethyl, propionyl and benzoyl compounds of (-) - 3-hydroxy-N-allyl-, -propargv'l-, -metha: llyl-, -erotyl-, -propy are obtained l- or -isobuty l-morphinane.



  Some of the starting materials are known. (for (-) - 3-IIydros. -N-allyl-morphinan see Hel v. 34, 2217 [1.951]) or can be added to (-) - 3-hydroxy-morphinan in an analogous manner to the known compound by heating with the corresponding saturated or unsaturated alkyl halide: shown. will;

   the N-propyl and N-isobtityl compounds can also be obtained from the N-allyl or N-3-tethally1 compound by catalytic hydrogenation.



       Example <I> 1 </I> 30 g (-) - 3-hydroxy-N-allyl-morphinan are heated to 80 ° C. for 4 hours with 150 cm3 of acetic anhydride. The reaction solution is evaporated in vacuo, the residue is dissolved in benzene and washed with ice-cold sodium carbonate solution and ice water.

   With. Sodium sulfate-dried benzene solution is evaporated in vacuo and the (-) - 3-acetoxy-Na.llyl-morphinan is distilled in a high vacuum. Boiling point at 0.001 mm Hg156 C. The hydrobromide, crystallized from Butwlaeetat, melts at 212-214 C and shows a rotation of [a] D = -41.4 (c = 3 in fine fuel).



       Example <I> 2 </I> 50 g (-) - 3-hydroxy-N-allyl-morphinan are suspended in 500 cma acetone and mixed with stirring at 25-30 ° C. 30 cm3 of benzoyl chloride added. The (-) - 3-hydroxy-N-allyl-morphinan dissolves quickly and after a short time the (-) - 3-benzoyloxy-N-allyl-morphinan hydrochloride crystallizes out.

    After suctioning off, washing with ethyl acetate and redissolving from butyl acetate, the compound melts
