Polyazamacrocycles and their derivatives are appreciated for the strength of their corresponding metal complexes. 1,4,7-Triazacyclononane (TACN) derivatives have been employed in an ever increasing number of applications. To this day, all synthetic routes to TACN derivatives that have identical or differing substituents require the initial preparation of unprotected TACN. Herein, we report the four-step synthesis of TACN derivatives that have a 2Ra/Rb N-functionalization pattern by starting from diethylenetriamine and employing an organic template strategy.

Eleven lipophilic derivatives of the title biogenic amines and 28 structurally related triamines and tetramines have been synthesized. Twenty-three of them inhibited the platelet aggregation induced by collagen at an IC50 between 8 mumol/L and 30 mumol/L. Five compounds prolonged the one stage thromboplastin time (Quick) by 7s or more at 100 mumol/L. The antiplatelet and anticoagulant effect do not run parallel. The relationship between the effects observed and the chemical structure of the oligoamines has been elucidated.
