A new class of C3-symmetrical hemicryptophane hosts: triamide- and tren-hemicryptophanes.
The first hemicryptophanes derived from tris(N-alkyl-carbamoylmethyl)amine and tris(2-aminoethyl)amine (tren) have been synthesized following a single synthetic pathway that allows the subsequent formation of the two heteroditopic hosts 3 and 4. X-ray crystal structures show a well-defined cavity encapsulating a solvent guest for both compounds emphasizing their complexation properties.
