A Ru(ii) complex mediated synthesis of various N,N-dimethyl and N-monomethyl amines from organic azides using methanol as a methylating agent is reported. This methodology was successfully applied for a one-pot reaction of bromide derivatives and sodium azide in methanol. Notably, by controlling the reaction time several N-monomethylated and N,N-dimethylated amines were synthesized selectively. The practical applicability of this tandem process was revealed by preparative scale reactions with different organic azides and synthesis of an anti-vertigo drug betahistine. Several kinetic experiments and DFT studies were carried out to understand the mechanism of this transformation.

On the basis of its essential role in driving inflammation and disease pathology, cell necrosis has gradually been verified as a promising therapeutic target for treating atherosclerosis, systemic inflammatory response syndrome (SIRS), and ischemia injury, among other diseases. Most necrosis inhibitors targeting receptor-interacting protein 1 (RIP1) still require further optimization because of weak potency or poor metabolic stability. We conducted a phenotypic screen and identified a micromolar hit with novel amide structure. Medicinal chemistry efforts yielded a highly potent, selective, and metabolically stable drug candidate, compound 56 (RIPA-56). Biochemical studies and molecular docking revealed that RIP1 is the direct target of this new series of type III kinase inhibitors. In the SIRS mice disease model, 56 efficiently reduced tumor necrosis factor alpha (TNFα)-induced mortality and multiorgan damage. Compared to known RIP1 inhibitors, 56 is potent in both human and murine cells, is much more stable in vivo, and is efficacious in animal model studies.
