Starting from the 2,8-dibromo- and the 2,8-diiodo-substituted Troeger's base analogues 1 and 2, several new symmetrically disubstituted derivatives 4, 5, and 7-17 could be obtained by transition metal-catalyzed cross-coupling reactions or other functionalizations like borylation or protecting group operations. For the first time, conditions for a highly efficient Suzuki cross-coupling reaction involving
