Claim 0:
1. A composition comprising at least one compound which is represented by formula II:, wherein Re is an optionally substituted C6-C24 aryl group or an optionally substituted C6-C24 alkylaryl group;
wherein Rz is (i) a monovalent optionally substituted C1-C12 alkyl group, or (ii) a bivalent optionally substituted C1-C12 alkylene group, which bonds to the optionally substituted C6-C24 aryl group or the optionally substituted C6-C24 alkylaryl group of the Re moiety forming a ring, wherein the ring is an unsaturated lactone;
wherein when Re and/or Rz is a substituted functional group, the substituent is nitro, alkyl, halogen, amino, nitrile, alkoxy, aldehyde, carboxylic acid, ester, or hydroxyl;
wherein Rf represents a hydrogen atom, a halogen atom, a nitro group, a cyano group or C1-C8-alkyl, C2-C8 alkenyl, C2-C8-alkynyl, or C3-C8-cycloalkyl;
wherein when Ra is hydrogen, Rb is hydrogen, and Rc is methyl, Rf is hydrogen; and
wherein Ra, Rb and Rc, independently from each other, represent:
(a) a hydrogen atom, a halogen atom, a nitro group, a cyano group, a formyloxy group, a formylamino group or a carbamate group,
(b) a substituent R1, wherein R1 represents C1-C8-alkyl, C2-C8 alkenyl, C2-C8-alkynyl, C3-C8-cycloalkyl, or C1-C8-alkoxy, each of which are optionally substituted,
(c) a substituent —OR2, wherein R2 represents a hydrogen atom, C1-C8-alkyl, C2-C8-alkenyl, C2-C8-alkynyl, C1-C8-alkylcarbonyl, C1-C8-alkylaminocarbonyl or C1-C8-alkoxycarbonyl, each of which are optionally substituted,
(d) a substituent —NR3R4, wherein R3 and R4, independently from each other, represent a hydrogen atom, C1-C8 alkyl, C1-C8-alkylcarbonyl, C1-C8-halogenoalkylcarbonyl, phenyl or benzyl, each of which are optionally substituted,
(e) a substituent —(O)—R5, wherein R5 represents a hydrogen atom, C1-C8-alkyl or C1-C8-alkyloxy, each of which are optionally substituted, —NH2, NHR5 or NR5R5 where the two substituents R5 may be the same or different, —NR5 (OH),
(f) a substituent —S(O)n—R6, wherein n is 0, 1 or 2 and R6 represents C1-C8-alkyl which is optionally substituted, —NH2, —NHR6 or NR6R6 where the two substituents R6 may be the same or different, or
(g) a 4-, 5-, 6- or 7-membered heterocyclic ring comprising up to 4 heteroatoms selected from nitrogen, oxygen or sulfur, each of which are optionally substituted,
wherein substituents in (a)-(g) are halogen, nitro, amino, nitrile, alkoxy, or hydroxyl; and
wherein compounds formula (VI) are excluded:, wherein:
(i) R is methyl, X is H and n=0;
(ii) R is methyl, X is H, and n=1;
(iii) R is methyl, X is H, and n=2;
(iv) R is methyl, X is Cl, and n=0;
(v) R is methyl, X is —OCH3 and n=0; and
(vi) R is methyl, X is H, n=1, and R is bonded to —(CH2)n-forming a ring.
