Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>First‐ and fourth‐generation phosphorus dendrimers decorated on their surface with (+)‐cinchonine moieties for the use as organocatalysts have been prepared. The first‐generation dendrite showed the highest activity and enantioselectivity in the α‐amination of several β‐dicarbonyl compounds. A positive dendritic effect was observed. Its recovery and reuse over 10 cycles was demonstrated without loss of activity. Preliminary studies of the scope of the reaction have been performed.</p> </abstract>
