Endogenous formation of dimethylamine [PDF]

Biochemical Journal, 1985
An understanding of the biosynthesis and metabolism of dimethylamine (DMA) is important because it is a precursor of dimethylnitrosamine (nitroso-DMA). DMA is the major short-chain aliphatic amine in human and rat urine. DMA is formed from trimethylamine (TMA), which, in turn, is a breakdown product of dietary choline.

Regiodivergent C3 and C4 Amination of Quinolines via Radical and Ionic Pathways

Angewandte Chemie, EarlyView.
A regiodivergent strategy converts a single N‐aminoquinolinium precursor into either C3‐ or C4‐aminated quinolines. Nucleophile‐induced dearomatization diverges into light‐driven N‐centered radical capture (C3) or base‐promoted SNAr (C4), enabling rapid assembly of aminoquinoline libraries and late‐stage diversification.
