Patent ID: 7357989

Claim:
A thiazole derivative having the following structure: wherein R 1 , R 2 , R 3 , and R 4 are selected from the group consisting of: a) R 1 , R 2 , R 3 , and R 4 are individual substituent groups, and R 1 , R 2 , and R 3 independently of one another are: R 1 is a bifunctional (het)arylene system, which optionally comprises linearly or angularly fused or linked identical or different ring types, and peripheral hydrogen atoms optionally substituted by alkyl, alkoxy, phenoxy, dialkylamino or diphenylamino groups, wherein alkyl is C 1 to C 6 ; R 2 is a monofunctional (het)aryl system, which optionally comprises linearly or angularly fused or linked identical or different ring types and peripheral hydrogen atoms optionally substituted by alkyl, alkoxy, phenoxy, dialkylamino or diphenylamino groups, wherein alkyl is C 1 to C 6 ; and R 3 is i) a monofunctional (het)aryl system, which optionally comprises linearly or angularly fused or linked identical or different ring types and peripheral hydrogen atoms optionally substituted by alkyl, alkoxy, phenoxy, dialkylamino or diphenylamino groups, wherein alkyl is C 1 to C6, ii) R 7 , R 7 being a chemical bond or a bifunctional (het) arylene system, R 7 being a chemical bond or a bifunctional (het)arylene system, or b) R 1 and R 2 are individual subsituent groups, and R 3 and R 4 together form an individual sustituent group, selected from the group consisting of: R 7 being a chemical bond or a bifunctional (het)arylene system, and Y being CH or N; c) R 2 and R 4 are individual subsituent groups, and R 3 and R 1 together form an individual substituent group: R 7 being a chemical bond or a bifunctional (het)arylene system; d)R 2 and R 3 are individual subsituent groups, and R 4 and R 1 together form an individual substituent group: e) R 2 is an individual substituent group, and R 3 and R 4 together with R 1 form an individual substituent group: R 7 being a chemical bond or a bifunctional (het)arylene system, and Y being CH or N.
