TADDOL-based phosphorus(iii)-ligands in enantioselective Pd(0)-catalysed C-H functionalisations.

Monodentate TADDOL-derived phosphoramidites and phosphonites are versatile chiral ligands for enantio-selective Pd(0)-catalysed C-H functionalisations. They enable highly selective cyclisations to access a wide range of chiral carbo-and heterocycles. The high attractiveness of this ligand class consists in their modular structure, allowing for a quick assembly of a library with variable steric properties. Asymmetric C-H functionalisation methods utilising catalytic systems based on Pd(0) complexes and TADDOL-type ligands are presented and aspects of selectivity are discussed.
