synthetic approach to symmetrical diamino-substituted Troger's base analogues, allowing the synthesis of 1,7-, and 4,10-diamino derivatives with no additional substituents and of 3,9-diamino derivative with methyl groups in the 1-, 4-, 7- and 10-positions. The synthesis uses regioselective nitration of dihalo-substituted- or tetrahalo-substituted Troger'sbases followed either by hydrogenation of the nitro
