Chiral Ligands for Au(I), Au(III), and Au(I)/Au(III) Redox Catalysis

Abstract

AbstractGold catalysis has emerged as an efficient tool for the selective functionalisation of C−C multiple bonds. Despite significant progress in this field, the potential of asymmetric gold catalysis has not been fully explored to date. A historical retrospect on the progress in this area reveals that enantioselective gold catalysis is based on three pillars: Au(I) catalysis, Au(III) catalysis, and Au(I)/Au(III) redox catalysis. Irrespective of the mode of catalysis being operative, the design of new ligands is crucial for the development of gold‐catalysed organic transformations. This minireview summarizes the progress made in the development of ligand design for enantioselective Au(I) catalysis, Au(III) catalysis, and Au(I)/Au(III) redox catalysis focusing on the ligands which were specially designed for gold catalysis.
