(EN) The present invention relates to a process for stereoselective cycloaddition reactions which generally comprises a cycloaddition reaction between a pair of substrates, each either chiral or prochiral, that contain reactive $g(p)-systems, in the presence of a non-racemic chiral catalyst, to produce a stereoisomerically enriched product.(FR) L'invention porte sur un processus à base de réactions stéréosélectives de cycloaddition, consistant en une réaction de cycloaddition entre une paire de substrats dont chacun est chiral ou prochiral contenant des systèmes $g(p) réactifs, en présence d'un catalyseur chiral non racémique, d'où résulte un produit enrichi en stéréoisomères.

The present invention relates to a process for stereoselective cycloaddition reactions which generally comprises a cycloaddition reaction between a pair of substrates, each either chiral or prochiral, that contain reactive &pgr;-systems, in the presence of a non-racemic chiral catalyst, to produce a stereoisomerically enriched product. The present invention also relates to novel asymmetric catalyst complexes comprising a metal and an asymmetric tridentate ligand.
