We developed an efficient fluorination protocol that converts easily accessible aziridines into β-fluoroamines, which are important motifs in biologically active molecules. In contrast with traditional fluorination approaches, DMPU-HF has shown both higher reactivity and regioselectivity and good functional group tolerance; thus, a wide scope of β-fluoroamines can now be accessed conveniently. The stereochemical behavior of ring opening depends on the substitution pattern of the aziridine substrates. DMPU-HF demonstrates good reactivity and regioselectivity in conversion of aziridines into biologically important β-fluoroamines. The stereochemistry of aziridine-opening was found to be depend greatly on substitution pattern.
