the development of a method for selective remoteC(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

The development of an electrochemically driven, ruthenium-catalyzed C–H hydroxylation reaction of amine-derived substrates bearing tertiary C–H bonds is described. The reaction is performed under constant current electrolysis in a divided cell to afford alcohol products in yields comparable to those of our previously reported process, which requires the use of stoichiometric H5IO6 for catalytic turnover

The use of 1,3-dibenzyl-5-substituted-hexahydro-2-oxo-1,3,5-triazine ("dibenzyltriazone") as a protecting group for primary amino is described. Optimized conditions for formation and hydrolysis of dibenzyltriazones, as well as a variety of transformations (reduction, oxidation, hydroxyl modification, C-C bond formation) compatible with this protecting group, are presented. N-Protected amino aldehydes such as 46, 47, and 94 are particularly valuable building blocks, as demonstrated by the syntheses of hypusine (86), deoxyhypusine (85), spermidine (74), and two unsaturated spermidine analogues 81 and 84.
