Definitions
- the present invention relates to colored polyphenoxydendrimers, new soluble supports, their preparation process and their use in organic synthesis.
- the present invention more specifically relates to the use of colored dendrimers as soluble supports in organic synthesis, these colored dendrimers and their process of preparation.
- Combinatorial chemistry is increasingly used by chemists as a new technology allowing the synthesis of a very large number of products.
- This technique the advantage of which is that it allows rapid synthesis of a very large number of products, however, does not make it possible to synthesize a large quantity of each of these products: combinatorial chemistry is therefore a very useful technique for example in screening of a large number of products for which it is desired to seek a particular activity such as for example an affinity of these products for a particular receptor.
- Dendrimers are fractal molecules also called molecular trees or cascading molecules. These names evoke the structure of these compounds made up of trees diverging from a central core, and built step by step, generation after generation.
- the dendrimers are therefore, tree-like monodispersed polymers, at the interface of classical chemistry and polymer chemistry, used in many fields: as catalysts in organometallic chemistry, to study the interactions between carbohydrates and proteins in glycobiology, as vectors of biomolecules for example in agrochemicals or in pharmacies.
- Vôgtle (Buhleier, EW, ehner, W.; Vôgtle, F., Synthesis 1978, 155-158) and especially developed with Tomalia (Tomalia , DA; Baker, H.; Dewald, JR; Hall, M.; Kallos, G.; Matin, S.: Roeck, J.; Ryder, J.; Smith, P. 1) Polym. J. (Tokyo) 1985, 17, 117-132; 2) Macromolecules 1986, 19, 2466-2468).
