Description

  

  <B>Verfahren zur Herstellung von</B>     Glykosiden   <B>des</B>     Sulfanilamids.       Die Herstellung von     Glykosiden    des     p-          Amino-benzolsulfonamids,    welche von thera  peutischer Bedeutung sind, ist bekannt [vgl.  Berichte der Deutschen Chemischen Gesell  schaft 71 (1938), 621]. Die den Gegenstand  dieser Veröffentlichung bildenden Befunde  gründen sich unter anderem auf die An  nahme, dass die Umsetzung von Mono- und       Polysacchariden        mit    gewissen aromatischen  Aminen, darunter     Sulfanilamid,    am besten in  Gegenwart von     Ammoniumchlorid    als Kata  lysator erfolge.

   Die Autoren vertreten die An  sicht, dass wegen der Bildung von Ammoniak  bei der Umsetzung intermediär Chlorhydrate  entstehen. Sie motivieren damit die     kataly-          tisehe    Wirkung des     Ammoniumchlorids,    wel  che im Falle der Sulfonamide diejenige des  Chlorwasserstoffes, welcher an sich als Kata  lysator für die     Glykosidierung    anderer Amine  als gut geeignet bezeichnet wird, übertreffe.  Die Ausbeute von zum Beispiel     Sulfanilainid-          d-glukosid        wird        zu        80%        angegeben.     



  In einem gewissen Widerspruch     mi    den in  dieser Arbeit aufgestellten Hypothesen wurde  nun überraschenderweise gefunden, dass die  Umsetzung des     Sulfanilamids    mit Mono- oder       Polysacchariden    besonders gut verläuft, wenn  man die Komponenten in Gegenwart von ver  dünnten organischen Säuren     -:    gegebenen  falls in zusätzlicher Anwesenheit von Salzen  organischer Säuren - miteinander reagie  ren lässt.

   Es werden dabei Ausbeuten von       über        90        bis        100%        erhalten.       <I>Beispiele:</I>  1. 17,2 g     Sulfanilamid    und 18 g Glukose  werden in 100     cm3    heissem Wasser gelöst.  Diese Lösung wird mit 4     cm3        5n-Essigsäiire     versetzt, worauf man 30 Minuten kochen lässt.  Man lässt erkalten und saugt den abgeschie  denen Niederschlag ab. Nach Aufarbeitung  der Mutterlauge erhält man 32 g reines     Sul-          fanilsäureamid-d-glukosid    vom Schmelzpunkt  2121 (=     971/o    der Theorie).  



  2. Eine Lösung von 17,2 g     Sulfanilamid     und 34,2 g     Maltose    in 100     cm3    einer     0,01n-          Essigsäure    wird etwa 2 Stunden auf dem  Wasserbad erwärmt. Man arbeitet in üblicher  Weise auf und erhält 45 g     Sulfanilamid-d-          maltosid        =        90        %        der        Theorie.     



  3. Es werden in einer Lösung von 1 g       Natriumacetat    und 2     cm3    Essigsäure in  200     cm3    Wasser 43 g     Sulfanilamid    und 38 g       1-Arabinose    gelöst. Man erhitzt 5 Stunden  auf<B>800</B> und lässt sodann erkalten. Man erhält  68 g     Sulfanilamidarabinosid    vom Schmelz  punkt 1910.  



  4. 9 g     Sulfanilamid    und 9 g Glukose wer  den in 100     cm3    heissem Wasser gelöst und mit  3 g Bernsteinsäure versetzt. Nach     40minuti-          gem    Kochen lässt man in Eiswasser abkühlen  und saugt dann den feinkristallenen Nieder  schlag ab. Man erhält reines     Sulfanilsäure-          amid-d-gliikosid    mit einer Ausbeute von     931/o     der Theorie.



  <B> Process for the production of </B> glycosides of <B> the </B> sulfanilamide. The preparation of glycosides of p-amino-benzenesulfonamide, which are of therapeutic importance, is known [cf. Reports of the German Chemical Society 71 (1938), 621]. The findings forming the subject of this publication are based, inter alia, on the assumption that the reaction of mono- and polysaccharides with certain aromatic amines, including sulfanilamide, is best carried out in the presence of ammonium chloride as a catalyst.

   The authors take the view that, due to the formation of ammonia, intermediate chlorohydrates are formed during the conversion. They motivate the catalytic effect of ammonium chloride, which in the case of sulfonamides surpasses that of hydrogen chloride, which is known as a catalyst for the glycosidation of other amines. The yield of, for example, sulfanilainide-d-glucoside is stated to be 80%.



  In a certain contradiction with the hypotheses made in this work, it has now surprisingly been found that the reaction of the sulfanilamide with mono- or polysaccharides proceeds particularly well if the components are used in the presence of dilute organic acids -: if necessary in the additional presence of salts organic acids - can react with one another.

   Yields of over 90 to 100% are obtained. <I> Examples: </I> 1. 17.2 g sulfanilamide and 18 g glucose are dissolved in 100 cm3 hot water. 4 cm3 of 5N acetic acid are added to this solution and the mixture is left to boil for 30 minutes. It is allowed to cool and the deposited precipitate is sucked off. After working up the mother liquor, 32 g of pure sulphanilic acid amide-d-glucoside with a melting point of 2121 (= 971 / o of theory) are obtained.



  2. A solution of 17.2 g of sulfanilamide and 34.2 g of maltose in 100 cm3 of 0.01N acetic acid is heated on a water bath for about 2 hours. Working up in the usual way gives 45 g of sulfanilamide-d-maltoside = 90% of theory.



  3. 43 g of sulfanilamide and 38 g of 1-arabinose are dissolved in a solution of 1 g of sodium acetate and 2 cm3 of acetic acid in 200 cm3 of water. The mixture is heated to <B> 800 </B> for 5 hours and then allowed to cool. 68 g of sulfanilamide arabinoside with a melting point of 1910 are obtained.



  4. 9 g of sulfanilamide and 9 g of glucose are dissolved in 100 cm3 of hot water and 3 g of succinic acid are added. After boiling for 40 minutes, it is allowed to cool in ice water and the fine crystalline precipitate is then suctioned off. Pure sulfanilic acid amide-d-glycoside is obtained with a yield of 931% of theory.
