Abstract:	Phosphorus dendrimers containing terminal phosphoramidite ligands have been found to be highly effective and recoverable catalysts for the rhodium(i) catalyzed [2+2+2] cycloaddition reactions. A strong positive dendritic effect is observed both in the activity and enantiodiscrimination leading to axially chiral biaryl compounds We would like to thank the Spanish MICINN (project CTQ2011-23121), the Generalitat de Catalunya (project 2009SGR637) and the CNRS (France) for their financial support. L. G. thanks the Universitat de Girona (UdG) for a predoctoral fellowship
