Asymmetric C(sp(2) )-H activation.

A "niche" topic in the past decade, the asymmetric C-H bond activation has been attracting growing interest over the last few years. Particularly significant advances have been achieved in the field of direct, stereoselective transformations of C(sp(2) )-H bonds. This Concept article intends to showcase different types of asymmetric C(sp(2) )-H bond activation reactions, emphasising both the nature of the stereo-discriminating step and the variability of valuable scaffolds that could be rapidly constructed by means of such strategies.
