Description
Verfahren zur Herstellung neuer Benzolsulfonylsemicarbazide
Es ist bekannt, dass verschiedene Benzolsulfonyl- harnstoffe blutzuckersenkende Eigenschaften aufwei- sen, und als oral verabreichbare Antidiabetika geeignet sind ! [vgl. beispielsweise Arzneimittel-Forschung, Band 8, Seiten 448-454 (1958)]. Insbesondere der Nt-Sulfanilyl-N2- (n-butyl)-harnstoff und der Ni- (4- Methyl-benzolsulfonyl)-N2- (n-butyl)-harnstoff haben in der Diabetestherapie grosse Bedeutung ertangt.
Es wurde nun gefunden, dass kernbalogenierte BenzolsuPlfonylLsemicarbazide, bei denen das Stickstoffatom 1 mit einer 3 bis 5 Kohlenstoffatome enthaltenden Alkylenkette unter Ringbildung verbunden ist, eine sehr starke blutzuckersenkende Wirksamkeit bei einer durchweg ausserordentlich guten Verträg- lichkeit besitzen. Diese gute Verträglichkeit ermög- licht bei der Anwendung der neuen Verbindungen als orale Antidiabetika eine weitgehende Differenzierung in der Diabetes-Behandlung hinsichtlich der Faktoren Wirkungsstücke und Verweildauer, die bei den ein zelnen Vertretern auch dieser Körperklasse nach der einen oder nach der anderen Richtung wechseln.
Gegenstand der vorliegenden Erfindung ist demgemäss ein Verfahren zur Herstellung von Benzolsulfonyl-semicarbaziden der Formel
EMI1.1
in welcher Rl Halogen und Z eine 3 bis 5 Kohlen- stoffatome enthaltende Alkylengruppe, welche einoder mehrfach durch niedere Alkylreste substituiert sein kann, bedeuten.
Das erfindungsgemässe Verfahren ist dadurch gekennzeichnet, dass man Benzolsulfonyl-Verbindiungen der Formel
EMI1.2
mit Verbindungen der Formel
EMI1.3
umsetzt, wobei die Substituenten X und Y zur Bildung der Hamstoffbrücke geeignete Reste darstellen.
Die erhaltenen BenzolsuNonylsemicarbazide können in ihre Salze übergeführt werden.
Man setzt also z. B. ein Sulfonamid (zweckmässi- gerweise in Form des Natrium-oder Kaliumsalzes) mit einem Cycloalkylenimino-isocyanat um, oder man kondensiert-in Umkehrung dieser Reaktion-ein Sulfonylisocyanat mit einem Cydoalkylenhydrazin oder seinen Acyld'erivaten. Anstelle der Isocyanate konmen hierbei jeweils Verbindungen eingesetzt werden, welche unter den Reaktionsbediingungen in einen Isocyansaureester übergehen. Als derartige Isocyanat- bildner sind z.
B. geeignet einerseits Carbaminsäure- halogenide, Urethane bzw. Thiourethane, Harnstbffe sowie deren Acylderivate, Disulfonyl-harnstoffe und anderseits vorwiegend Semicarbazide.
Man kann auch derart vorgehen, dass man Ben zolsulfonylhalogenide, in denen der Substituent X ein Halogenatom, z. B. Chlor, ist, mit Semicarbaziden der genannten Formel umsetzt, in der Y die Gruppe H2N-CO-NH-darstelL't. Dabei verwendet man vor teilhaft die entsprechenden Parabansäure-Derivate.
Beispiele 1. 4- (p-Chlor-benzolsulfonyl)-1, 1-tetramethylen- semicarbazid 24,9 g N (p-Chlor-benzolsulfonyl)-methylurethan werden mit 8,6 g N-Amino-pyrrefiidin 25 Minuten auf 130'erhitzt,. Das feste Reaktionsprodukt wird in verdünntem Ammoniak gelöst, die Lösung mit Kohle gekliÅart und das Filtrat mit verdünnter Essigsäure angesäuert. Nach dem Absaugen, Waschen mit Wasser und Trocknen erhält man das SulfonyT-semicarbazid in sehr guter Ausbeute und praktisch rein. Nach dem Umkrist, allisieren aus Methylglykol liegt der Fp. bei 205-207 (Zers.).
In analoger Weise erhält man unter Verwendung von N-Aminopiperidin-das
4- (p-Chlor-benzolsulfonyl) 1, 1-pentamethylen semicarbazid, das nach dem Umkristalisieren aus Methanol/Di- methylfonnamid den Fp. 213-214 zeigt.
2.4-(p-FTuorbenzoIsu!!fonyD-1,l-pentamethylen semicarbazid 23, 3 g N-(p-Fluorbenzolsulfonyl)-methylurethan werden in 50 ml Xylol suspendiert und unter Rüh- ren auf 90 erhitzt, wobei das Urethan in Lösung geht. Man lrÅasst 10,5 g N-Amino-piperidin zutropfen und erhöht die Temperatur auf 110 . Das bei der Reaktion sich bildende Methanol wird abdestilliert.
Danach wird 30 Minuten auf 140 Aussentemperatur erhitzt. Nach Abkühlen wird das in feinen Nadeln ausgefallene Semicarbazid abgesaugt und mit Methanol und Äther gewaschen. Nach Umkristall'isation aus Dimethylformamid beträgt der Schmelzpunkt des
4-(p-Fluorbenzolsulfonyl)-1, 1-pentamlethylen semicarbazids 190-192 .
In analoger Weise erhält man unter Verwendung von N-Amino-pyrrolidin d'as
4-(p-Fluorbenzolsulfonyl)-1,1 tetramethylen semicarbazid, welches nach dem Umkristallisieren aus Dimethyl- formamid bei 175-177 schmilzt.
3.4- (p-Brombenzolsulfonyl)-1, 1-pentamethylen ; semicarbazid
Eine Suspension von 29, 4 g N-(p-Brombenzol- sulfonyl) - methylurethan (0, 1 Mol) in 230 ml abs.
Toluol wird mit 10 g N-Amino-piperidin 30 Minuten bei Zimmertemperatur gerührt. Hierauf wird 11/4 Stunde im Ölbad unter Rühren zum Sieden erhitzt.
Aus der klaren Reaktionslösung kristallisiert beim Abkühlen'dasobigeSemicarbazid aus. Nach dem Waschen mit Methanol hat es den Fp. von 227-230 .
Ausbeute : 30 g (83 % d. Th.).
In analoger Weise erhält man durch Umsetzung mit dem N-Amino-pyrrolidin das
4- (p-Brombenzolsulfonyl)-1, 1-tetramethylen semicarbazid ; Fp. 219 .
4. Durch Umsetzung vom kernhalogenierten Ben zolsulfonyl-urethanen mit niederatkylierten N-Amino- pyrrolidinen und N-Amino-piperidinen lassen sich unter stochiometrischer Abwandlung der in-den, vorstehenden Beispielen angegebenen Bedingungen die folgenden Semicarbazide gewinnen : 4- (p-Chlorbenzolsulfonyl)-1, 1- (a-methylpenta- methylen)-semicarbazid, Fp. 214-216 ; 4-(p-Chlorbenzolsulfonyl)-1, l-(l,@-methylpenta- methylen)-semicarbazid, Fp. 223-225 ;

Process for the preparation of new benzenesulfonylsemicarbazides
It is known that various benzenesulfonyl ureas have blood sugar-lowering properties and are suitable as orally administered antidiabetic agents! [see. for example, Arzneimittel-Forschung, Volume 8, pages 448-454 (1958)]. In particular, the Nt-sulfanilyl-N2- (n-butyl) -urea and the Ni- (4-methylbenzenesulfonyl) -N2- (n-butyl) -urea have gained great importance in diabetes therapy.
It has now been found that nucleus-balanced benzene sulfonyl semicarbazides, in which the nitrogen atom 1 is linked to an alkylene chain containing 3 to 5 carbon atoms with formation of a ring, have a very strong blood sugar-lowering activity with an extraordinarily good tolerance throughout. When the new compounds are used as oral antidiabetic agents, this good tolerability enables extensive differentiation in diabetes treatment with regard to the factors of effects and length of stay, which change in one direction or the other in the individual representatives of this body class.
The present invention accordingly provides a process for the preparation of benzenesulfonyl semicarbazides of the formula
EMI1.1

B. a sulfonamide (conveniently in the form of the sodium or potassium salt) with a cycloalkylene imino isocyanate, or a sulfonyl isocyanate is condensed with a cycloalkylene hydrazine or its acyl derivatives, in reverse of this reaction.

B. chlorine, is reacted with semicarbazides of the formula mentioned, in which Y represents the group H2N-CO-NH-darstelL't. The corresponding parabanic acid derivatives are used before geous.
