Description
Die Herstellung der neuen Verbindungen erfolgt in der Weise, daß man ein Pyrimidopyrimidin der Yormel 11 in der die beiden Reste R gleich sind und die eingangs erwähnten Bedeutun-. gen aufweiseng mit reduzierenden Mitteln behandelt und die erhaltenen 1,2,3,4-Tetrahydroverbindungen der Formel III oxydiert. Als reduzierende Mittel haben sich naazierender oder katalytisch erregter Wasserstoff sowie die elektrolytische Reduktion als besonders vorteilhaft erwiesen, die Reduktion wird in Anwesenheit eines Lösungsmittels, insbesondere eines polaren Lösungsmitteln, vorzugsweise in schwach saurer Lösung bei einem pH von etwa 2 - 5 durchgeführt. Die erhaltenen Verbindungen der Formel III könneng zweckmäßig unter Luftausschluß, isoliert worden; vorteilhaft werden sie jedoch direkt mit einem üblichen Oxydationsmittel oxydiert. Als Oxydationsmittel können beispielsweise eine methanolische Brom- oder Jodlösung, Wasserstoffperoxid, Kaliumbromat oder Kaliumpermanganat verwendet werden. Der pH-Wert des Heaktionsgemisches richtet sich hierbei nach deiu verwendeten Oxydationsmittel: Oxydiert man beispielsweise mit einer Brom- oder Jodlösung, stellt man den pH-Wert zweckmäßig auf 6 oder darüber ein, man kann aber auch bei Verwendung von beispielsweise Kaliumper -.inganat oder Wasserstoffperoxid in saurem Bereich arbeiten.The new compounds are prepared in such a way that a pyrimidopyrimidine of the formula 11 in which the two radicals R are the same and have the meanings mentioned at the outset. gene have treated with reducing agents and the resulting 1,2,3,4-tetrahydro compounds of formula III oxidized. The reducing agents are naazierender or catalytically excited hydrogen and electrolytic reduction have proved to be particularly advantageous, the reduction is preferably in the presence of a solvent, particularly a polar solvent in weakly acidic solution at a pH of about 2 - carried out. 5 The compounds of the formula III obtained can advantageously be isolated with the exclusion of air; however, they are advantageously oxidized directly with a conventional oxidizing agent. A methanolic bromine or iodine solution, hydrogen peroxide, potassium bromate or potassium permanganate, for example, can be used as the oxidizing agent. The pH of the reaction mixture depends on the oxidizing agent used: If one oxidizes, for example, with a bromine or iodine solution, the pH is expediently set to 6 or above, but one can also use, for example, potassium peringanate or Hydrogen peroxide work in acidic range.
