The synthesis of six new examples of 2,8-dinitro-substituted Troger'sbaseanalogues are reported, together with the first examples of 1,7-, 3,9- and 4,10-dinitro Troger'sbaseanalogues and the first example of a tetranitro Troger'sbase compound. Several of these dinitro compounds lack substituents at the 2- and 8-positions and therefore provide further examples of Troger'sbaseanalogues derived
Abstract Eleven different derivatives of Tröger’s base were synthesized and successfully resolved by (recycling) HPLC on chiral stationary (S,S)-Whelk-O1 or CHIRALPAK IA phase on a (semi-) preparative scale or synthesized in enantiomerically pure form. The absoluteconfiguration was determined by X-ray crystal structure analysis, comparison of the quantum chemically calculated circular dichroism spectra
Five racemic dissymmetric bis(pyridyl) ligandsbased on 2,8‐ or 3,9‐difunctionalised Tröger’sbase derivatives have been synthesised. Only those derivedfrom a 2,8‐difunctionalised scaffold were found to undergo selective self‐assembly to discrete self‐assembled dinuclear metallosupramolecular aggregates of rhomboid shape upon coordination to cis‐protected Pd2+ or Pt2+ ions, as evidenced by ESI mass
