Novel Chiral Ligands-Enabled Transition-Metal-Catalyzed Asymmetric C-H Borylation

Although C-H borylation has been recognized as an efficient approach to organoboron compounds, the asymmetric variants have emerged only very recently. These results pointed out that the development of novel chiral ligands was pivotal to the success of asymmetric C-H borylation. Herein, a brief summary and comments on the key progresses are presented.
