Synthetic strategy for novel multiple Tröger's base derivatives is presented. Compounds were prepared in three steps: o-nitrobenzoylation of benzene-1,2- and -1,3-diamines 3 followed by reduction of nitro and amide groups to amino functions and treatment of the obtained tetraamine compounds 6 with formaldehyde lead to simultaneous formation of bis-Tröger's base (bisTB) derivatives 7a, 7b. Only products of 1,2,3,4-substituted regioisomers with anti conformation were separated from reaction mixtures. The same synthetic procedure was used for preparation of tris-Tröger's base (trisTB) derivative 12b starting from benzene-1,3,5-triamine (8).
