P-CHIRAL PHOSPHOLANES AND PHOSPHOCYCLIC COMPOUNDS AND THEIR USE IN ASYMMETRIC CATALYTIC REACTIONS

摘要

Chiral ligands and metal complexes based on such chiral ligands useful inasymmetric catalysis are disclosed. The metal complexes according to thepresent invention are useful as catalysts in asymmetric reactions, such as,hydrigenation, hydride transfer, allylic alkylation, hydrosilytation,hydroboration, hydrovinylation, hydroformylation, olefin metathesis,hydrocarboxylation, isomerization, cyclopropanation. Diels-Alder reaction,Heck reaction, isomerization, Aldol reaction, Michael addition; epoxidation,kinetic resolution and [m+n] cycloaddition. Processes for the preparation ofthe ligands are also described.
