Fremgangsmåte til fremstilling av benzotiadiazin-l,l-dioxyd-forbindelser med diuretiske og natriuretiske egenskaper. Process for the preparation of benzothiadiazine-1,1-dioxyd compounds with diuretic and natriuretic properties.
Foreliggende oppfinnelse angår fremstilling av nye benzotiadiazin-l,l-dioxyd-forbindelser inneholdende en sulfamyl-substituent i kjernens benzen-del. Den generelle formel for de nye forbindelser som fremstilles ifølge oppfinnelsen, er an-gitt nedenfor. I de forbindelser som ved et av nitrogenatomene i benzotiadiazin-1,1-dioxyd-kjernen ikke har andre substi-tuenter enn hydrogen, er dobbeltbindingen tautomer, dvs. den foreligger enten mellom atomene i 2- og 3-stillingen eller mellom atomene i 3- og 4-stillingen. I de forbindelser som har en substituent på nitrogenatomet i 2-stillingen, foreligger dobbeltbindingen mellom stillingene 3 og 4, og når nitrogenatomet i 4-stillingen har en substituent, foreligger der en umettet binding mellom 2- og 3-stillingen. Således kan i sin alminnelighet forbindelsene ansees å ha en av følgende generelle formler: The present invention relates to the production of new benzothiadiazine-1,1-dioxyd compounds containing a sulfamyl substituent in the benzene part of the core. The general formula for the new compounds produced according to the invention is given below. In the compounds which have no other substituents than hydrogen at one of the nitrogen atoms in the benzothiadiazine-1,1-dioxyd nucleus, the double bond is tautomeric, i.e. it exists either between the atoms in the 2- and 3-positions or between the atoms in the 3 - and the 4 position. In the compounds that have a substituent on the nitrogen atom in the 2-position, the double bond exists between the 3- and 4-positions, and when the nitrogen atom in the 4-position has a substituent, there is an unsaturated bond between the 2- and 3-position. Thus, in their generality, the compounds can be considered to have one of the following general formulas:
I disse generelle formler betegner R hydrogen, halogen, lavere alkylgrupper fortrinsvis med fra 1 til 5 kullstoffatomer, lavere alkoxygrupper likeledes fortrinsvis med fra 1 til 5 kullstoffatomer i radikalets al-kyldel, eller nitrogrupper, mens Ri betegner hydrogen eller et lavere alkylradikal fortrinsvis med 1 til 5 kullstoffatomer. In these general formulas, R denotes hydrogen, halogen, lower alkyl groups preferably with from 1 to 5 carbon atoms, lower alkoxy groups likewise preferably with from 1 to 5 carbon atoms in the alkyl part of the radical, or nitro groups, while Ri denotes hydrogen or a lower alkyl radical preferably with 1 to 5 carbon atoms.
De nye forbindelser som fremstilles The new compounds that are produced
ifølge foreliggende oppfinnelse er fordel-aktige kjemoterapeutiske midler særlig på grunn av sine dieuretiske og/eller natriuretiske egenskaper. Forbindelsene kan according to the present invention, advantageous chemotherapeutic agents are particularly due to their diuretic and/or natriuretic properties. The connections can
anvendes i terapeutiske doser med vanlige bærere, f. eks. i form av tabletter da disse forbindelser er effektive både ved oral anvendelse og ved injeksjon.
