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.
