Functionalized analogues of Tröger's base: scope and limitations of a general synthetic procedure and facile, predictable method for the separation of enantiomers
A major stumbling block in the applications of enantiomerically pure Tröger'sbase analogues is their poor availability. We have therefore developed a facile method for the enantioseparation of functionalized Tröger'sbase analogues possessing various substitution patterns. The systematic separation of a library comprising 36 representatives on the commercially available Whelk O1 chiral stationary

The one-step synthesis of a series of hybrid dibenzo Troger'sbaseanalogues bearing at least one halogen atom is described. The strategy involves a reaction between two different anilines and affords hybrid compounds in yields as high as 46 %, together with the symmetricTroger'sbase products. This straightforward approach requires only one chromatographic step and has the potential to replace multi-step

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
