Chiral phosphine ligands derived from chiral natural products including D- mannitol and tartaric acid. The ligands contain one or more 5-membered phospholane rings with multiple chiral centers, and provide high stereoselectivity in asymmetric reactions.

L'invention concerne des ligands de phosphine à structure chirale dérivés de produits naturels à structure chirale parmi lesquels figurent le D-mannitol et l'acide tartrique. Les ligands en question renferment un ou plusieurs cycles de phospholane à cinq chaînons comportant plusieurs centres chiraux, et ils assurent une stéréosélectivité élevée dans les réactions asymétriques.
