Patent ID: 7407910

Claim:
A compound of the formula I, wherein Y 1 and Y 2 are, independently of each other, P(═O), P(═S) or P; Z 1 , Z 2 , Z 3 and Z 4 are, independently of each other, halogen or an unsubstituted or substituted moiety selected from the group consisting of aryl, heterocyclyl, cycloalkyl, aryl-lower alkyl, heterocyclyl-lower alkyl, cycloalkyl-lower alkyl, alkyl, aryloxy, heterocyclyloxy, cycloalkoxy, aryl-lower alkoxy, heterocyclyl-lower alkoxy, cycloalkyl-lower alkoxy and alkoxy; or —N(Q) 2 wherein Q is unsubstituted or substituted alkyl or wherein N(Q) 2 forms an unsubstituted or substituted heterocycle optionally containing further heteroatoms; or hydrogen; or one or all of the pairs (i) Z 1 and Z 2 , and (ii) Z 3 and Z 4 , form bridges of any one of the formulae (A), (B), (C), (D), (E) and (F) wherein m is 1 to 5; n is 1 to 6; q is 0 to 6; A is a substituent, where the substituent or substituents A are independently unsubstituted or substituted moieties selected from the group consisting of alkyl, aryl, lower alkoxy or di-(lower alkyl)-amino, and/or two moieties A together form a methylendioxy or a C 3 -C 7 -alkylene bridge that are unsubstituted or substituted; or pairs of substituents A together with the binding carbon atoms form an unsubstituted or substituted annelated ring; or in formula (B), if m is 2 to 5, pairs of substituents A together with the binding carbon atoms form an unsubstituted or substituted annelated ring; or in formula (C), pairs of substituents A together with the binding carbon atoms form an unsubstituted or substituted annelated ring; X 4 is, independently of each other, O or NR 5 ; and R 5 is independently hydrogen or an unsubstituted or substituted moiety selected from the group consisting of alkyl, aryl, cycloalkyl, heterocyclyl, aryl-lower alkyl, cycloalkyl-lower alkyl heterocyclyl-lower alkyl, SO 2 R, SO 3 R, SO 2 NR, C(═O)R, C(═O)OR and C(═O)NR; while the residues from Z 1 , Z 2 , Z 3 and Z 4 , as far as they are not involved in bridge formation, are as defined above; X 1 is NR, O or S; X 2 is CHR 1 or CR 1 ; X 3 is CHR 2 or NR 2 or, if X 2 is CR 1 , X 3 is CR 2 or N; R, R 1 and R 2 , independently of each other, are hydrogen or an unsubstituted or substituted moiety selected from the group consisting of alkyl, aryl, cycloalkyl, heterocyclyl, aryl-lower alkyl, cycloalkyl-lower alkyl and heterocyclyl-lower alkyl or R 1 and R 2 together form an annealed unsubstituted or substituted mono-, bi- or polycyclic ring system.
