Our group is interested in developing dendrimers using molecules derived from renewables resources (pentoses, glycerol). The intended applications, at least initially, are to use these objects to include complexes of transition metals or metal nanoparticles1 in order to enhance their catalytic reactivity and to realize catalysis usually carried out in an organic medium in an aqueous or a micellar medium. The dendrimers are actually silicon-based2 (collaboration with the group of Pr. D. Astruc, Université Bordeaux I) or nitrogen-based3 amphiphilic dendrimers, both functionalized with a chiral surface (Figure 1). The preparation of these dendrimers and their use in catalysis will be presented.
