2,4,9-Triazaadamantanes (TRIADs) are promising yet scarcely available, conformationally rigid platforms for potential applications in the design of functional molecules and materials. Here, we report a facile synthesis of various N- and C7-substituted 2,4,9-triazaadamantanes, starting from amines and 4-allylhepta-1,6-dienes. A focus was placed on the synthesis of 2,4,9-triazaadamantanes bearing reactive groups (NH2, propargyl, OH) on the bridge nitrogen atoms, which were then used to decorate the 3D scaffold by hydrazone, triazole, and boronate linkages. A reversible opening of the adamantane cage to the acyclic tris-oxime form was observed for 2,4,9-triazaadamantanes possessing hydroxy-groups on the nitrogen atoms (TRIAD-triols). This process could be controlled by temperature or by complexation of TRIAD-triol with a boronic acid. The structure of 2,4,9-triazaadamantanes and the stereodynamics at the bridge nitrogen atoms were studied by X-ray analysis and DFT calculations.
