The present invention relates to nonlinear oligopyridazine compounds, to processes for obtaining them, to their uses, and also to their reduction to oligopyrroles and to the uses of the pyridazinylpyrrole and oligopyrrole compounds obtained. The invention relates in particular to the uses as medicaments, in particular for treating pathologies such as cancer, bacterial infections or parasitic infections, and also the uses in the materials, environmental, electronics and optics field.

are as defined in the specification. Further objects of the invention are processes and intermediates for the preparation of the compounds of the formula (I), pharmaceutical compositions comprising them and methods for treating cell proliferative disorders. As a matter of fact, the compounds of the formula (I) are useful, in therapy, in the treatment of diseases associated with a disregulated protein kinase activity, like cancer.
S(RN)1 reactions can be performed with nitrogen carbanions as nucleophiles, and generally the reaction leads to a mixture of isomers. In the case of the pyrrolyl anion, position 2 is about four times more reactive than position 3. When the ortho positions of pyrrole are substituted by alkyl groups, the reactivity of position 2 increases while that of position 3 decreases. With tert-butyl groups as the substituents, no reaction at position 2 is observed. With the indolyl anion as the nucleophiIe, no substitution at position 2 or at the phenyl ring is observed, and only one product corresponding to monosubstitution at position 3 is obtained. Imidazolyl anions react preferentially at position 4 (5), and substitution of position 2 by a methyl group makes the coupling regioselective.

The Stetter procedure has been adapted to produce oligomeric and polymericpyrrolylpyridines, which have been characterised by 13C NMR spectroscopy. The lower activity of 2-(pyrrol-2-yl)pyridines towards quaternisation permits selective N-alkylation of 2-, 3- and 4-(pyrrol-2-yl)pyridines.
Stetter程序已经过调整,可以生产低聚和聚合的吡咯基吡啶,这些化合物已通过13 C NMR光谱进行了表征。2-(吡咯-2-基)吡啶对季铵化的较低活性允许2-,3-和4-(吡咯-2-基)吡啶的选择性N-烷基化。
