title: Soluble Tetraaminotriptycene Precursors.
abstract: An efficient route to soluble triptycene tetraamines, shape-persistent molecules containing two ortho-phenylenediamine motifs, is reported. These tetraamines are stable, prepared in good yields, easily purified by column chromatography, and can be readily condensed to give a range of imidazole and pyrazine derivatives.
