  Verfahren zur Herstellung von unsymmetrisch disubstituierten Barbitursäuren. 



   In dem D. R. P. Nr. 293163 sind u. a. unsymmetrisch disubstituierte Barbitursäuren beschreieben. die neben einem alicyklischen Radikal noch einen Alkylrest enthalten. 



   Es wurde nun gefunden, dass die bisher noch unbekannten, unsymmetrisch disubstituierten Barbitursäuren, welche neben einem   ungesättigten   alieyklischen Rest einen gesättigten oder ungesättigten, Alkylrest enthalten, in ihrer praktisch therapeutischen Wirkung den im D. R. P.   Nr.     293163 bechriebfnen   Verbindungen noch überlegen sind. Einerseits sind die neuen Verbindungen von geringerer Giftigkeit. anderseits ist die Qualität des   Schlafes   eine weit bessere. Insbesondere rufen die neuen   Verbindungen   nicht die   Rausch- und Aufregungsznstände   hervor, wie sie bei Anwendung der   Verbindungen   des D. R. P. 



  Nr. 293163 zu beobachten sind.

  Process for the production of asymmetrically disubstituted barbituric acids.



   In D.R.P. No. 293163 are i.a. a. Describe asymmetrically disubstituted barbituric acids. which in addition to an alicyclic radical also contain an alkyl radical.



   It has now been found that the hitherto unknown, asymmetrically disubstituted barbituric acids, which in addition to an unsaturated alicyclic radical contain a saturated or unsaturated alkyl radical, are still superior in their practical therapeutic effect to the compounds described in D.R.P. No. 293163. On the one hand, the new compounds are less toxic. on the other hand, the quality of sleep is far better. In particular, the new compounds do not induce the levels of intoxication and excitement that occur when using the compounds of the D.R.P.



  No. 293163 can be observed.

   To prepare the new barbituric acid derivatives one proceeds in such a way that one uses the asymmetrically disubstituted malonic esters or cyano ester of the general formulas
