Asymmetric C3-Allylation of Pyridines.

Journal of the American Chemical Society, 2023
Asymmetric intermolecular C-H functionalization of pyridines at C3 is unprecedented. Herein, we report the first examples of such transformations: specifically, C3-allylation of pyridines via tandem borane and iridium catalysis.
