Remote C(sp3)-H Oxygenation of Protonated Aliphatic Amines with Potassium Persulfate

supporting information, p. 572 - 575 (2017/02/10)
This letter describes the development of a method for selective remote C(sp3)-H oxygenation of protonated aliphatic amines using aqueous potassium persulfate. Protonation serves to deactivate the proximal C(sp3)-H bonds of the amine substrates and also renders the amines soluble in the aqueous medium. These reactions proceed under relatively mild conditions (within 2 h at 80 °C with amine as limiting reagent) and do not require a transition metal catalyst. This method is applicable to a variety of types of C(sp3)-H bonds, including 3°, 2°, and benzylic C-H sites in primary, secondary, and tertiary amine substrates.

Silica gel and activated clay, behaving as Lewis acids, reacted with N-acyl-2,2-dimethylaziridines 1 to lead to pentacoordinated aziridinium silicate ions. The regiospecific ring opening on the CMe2 carbon side of the intermediate I involves, after remova

The neutral hydrolysis of N-acyl-2,2-dimethylaziridines gave rise to the amidoalcohols in 76-91% overall yields. These products resulted from the specific cleavage of the C-2-N bond.
