Methods for facile synthesis of symmetric and unsymmetric functionalized analogues of Tröger'sbase were developed with use of 2,8-dibromo-6H,12H-5,11-methanodibenzo[b,f][1,5]diazocine (2) as the starting material. C(2)-symmetric 2,8-disubstituted analogues of Tröger'sbase (4a-f) were synthesized via double bromine-lithium exchange of 2 followed by quench with electrophiles. Desymmetrization via single
The reactions between anilines and DMSO/HCl produce Troger'sbases in moderate yield. The Troger'sbasesbearing an electron-withdrawing group can also be synthesized through this procedure. In this reaction, DMSO/HClacts as formaldehyde equivalent.

In this paper, we report the synthesis of amino and aminomethyl derivatives of Tröger's base (±)-1 and (±)-2. The key steps in the synthesis of (±)-1 and (±)-2 are Pd-catalyzed amination and cyanation, respectively, of the easily accessible dihalo derivatives (±)-3. These compounds are important intermediates in the synthesis of new ligands and building blocks for H-bonded supramolecular architectures
