Abstract: | The synthesis of a set of new N-heteroaryltetramines is reported. A regioselective alkylation on the N-exo nitrogen of pyridinium N-(heteroaryl)aminide with the corresponding tetrabromo compounds, followed by a clean N-N bond reduction of the corresponding tetra-salts, allowed an easy and general method to obtain N,N′,N″,N?-tetrakis(2-heteroaryl)tetramines. |
