Synthesis of rigid polycyclic secondary diamines: Bis-(2,3 : 6,7-iminodimethylene)anthracene and bis-(2,3 : 6,7-iminodimethylene)-9,10-dicarboxyethenoanthracene

摘要

The synthesis of two rigid polycyclic secondary diamines, bis-(2,3:6,7-iminodimethylene)anthracene and bis(2,3:6,7-iminodimethylene)-9,10-dicarboxyethenoanthracene, by means of Diels-Alder reaction between 1,2,4,5-tetra(dibromomethyl)benzene and maleimides followed by imide reduction, is described. Furthermore, these two cyclic secondary diamines undergo acylation with N-protected amino acids, thus providing functionalized, amphiphilic. and chiral building blocks for incorporation into supramolecular systems.
