Estimating the term…
Compounds and use of the compounds for formula (I) where X is selected from the group consisting of a single bond, O, N—(C1-C4)-alkyl, N—Ar1, CR5R6, S, S(O) and SO2; Z1 and Z2 are independently selected from hydrogen, -Alk-OH, —CH2—Ar2—CH2—OH, -Alk′-C(O)ORx, —CH2—Ar2—C(O)ORx and —C(O)—Ar2—C(O)ORx, where Rx is selected from the group consisting of hydrogen, phenyl, benzyl and C1-C4-alkyl; R1 and R2 are independently selected from the group consisting of optionally substituted mono- or polycyclic aryl having from 6 to 26 carbon atoms as ring members and optionally substituted mono- or polycyclic hetaryl having a total of 5 to 26 atoms as ring members, R5 is selected from the group consisting of hydrogen, C1-C4-alkyl and a radical Ar1; R6 is selected from the group consisting of hydrogen and C1-C4-alkyl; Alk is C2-C4-alkandiyl; provided that R1 and R2 are not both phenyl, if R3 and R4 are both hydrogen.
