Chiral phosphoric acids: a chiral lobby for enantioselective C-H activation.

Enantioselective C-H activation is one of the promising methods to obtain enantiopure molecules in high enantiomeric excess with excellent control of regio and chemo-selectivity. The chiral phosphoric acids have evolved as the leading ligands in the enantioselective C-H activation. Chiral phosphoric acids can interact in different ways with the substrate to induce chirality into the system. This review summarizes the use of chiral phosphoric acids in the exciting field of enantioselective C-H activation.
