R 7 is chosen from hydrogen, —C(O)R 9 , or —CH 2 OC(O)R 9 ;
R 8 is chosen from hydrogen, alkyl, aryl, acyl, halo, alkenyl, alkynyl, alkoxy, cyano, or heterocyclyl, each optionally substituted with 0, 1, or multiple R 10 ,
R 9 is chosen from alkyl, alkoxy, or aryl, each optionally substituted with 0, 1, or multiple R 8 ;
R 10 is chosen from hydrogen, alkyl, aryl, acyl, halo, alkenyl, alkoxy, or heterocyclyl;
R 11 is chosen from hydrogen or alkyl, substituted with 0, 1 or multiple R 8 ;

a phytologically acceptable carrier material.

2. The composition according to claim 1 , wherein X is hydrogen and Y is Q.

3. The composition according to claim 2 , wherein R 6 is alkoxy.

4. The composition according to claim 3 , wherein R 7 is hydrogen.

5. The composition according to claim 4 , wherein R 1 and R 11 are independently chosen from hydrogen or alkyl, R 3 and R 12 are independently aryl, each optionally substituted with 0, 1 or multiple R 8 , and R 4 is H.

6. The composition according to claim 3 , wherein R 7 is chosen from —C(O)R 9 , or —CH 2 OC(O)R 9 .

7. The composition according to claim 6 , wherein R 9 is alkyl, optionally substituted with 0, 1 or multiple R 8 .

8. The composition according to claim 7 , wherein R 1 and R 11 are independently chosen from hydrogen or alkyl, R 3 and R 12 are independently aryl, each optionally substituted with 0, 1 or multiple R 8 , and R 4 is H.

9. The composition according to claim 8 , wherein R 9 is chosen from —CH 3 , —CH 2 OCH 2 CH 3 , —CH 2 CH 2 OCH 3 , —CH(CH 3 ) 2 , —CH 2 CH 2 CH 2 CH 3 , -cyclopropyl.
