Jin Choi et al.
Journal of the American Chemical Society, 143(31), 11927-11933 (2021-07-29)
The direct position-selective C-4 alkylation of pyridines has been a long-standing challenge in heterocyclic chemistry, particularly from pyridine itself. Historically this has been addressed using prefunctionalized materials to avoid overalkylation and mixtures of regioisomers. This study reports the invention of
