RhombiminesCyclic Tetraimines of <i>trans</i>-1,2-Diaminocyclohexane Shaped by the Diaryl Ether Structural Motif

Rhombimines, chiral macrocyclic tetraimines, are preferentially formed because of the structural bias in the reaction of aromatic ether-linked dialdehydes with enantiomerically pure trans-1,2-diaminocyclohexane.
