A synergistic strategy enables the selective synthesis of mono-N-methylated aliphaticprimaryamines, including deuterium-labelled drugs. This innovative approach combines an earth-abundant manganese catalyst with a weak base, resulting in a practical and sustainable protocol for mono-N-methylation. By effectively inhibiting the formation of formamide byproducts, it eliminates the need for external
AbstractThe palladium‐catalyzed ligand‐controlled arylation of α‐zincated acyclic amines, obtained by directed α‐lithiation and transmetalation, is described. Whereas PtBu3 gave rise to α‐arylated Boc‐protected amines, more flexible N‐phenylazole‐based phosphine ligands induced major β‐arylation through migrative cross‐coupling.
