Fig. 3: Synthesis and 1H NMR characterization of pseudo[1]catenanes.

Panel A shows the synthesis of diester derivatives rac-HOMO-1a and rac-HETERO-1b, and of diacid derivatives rac-HOMO-2a, and rac-HETERO-2b. Panel B shows 1H NMR spectra of the racemic diastereomer mixtures of the diester derivatives (500 MHz, 25 °C, CDCl3). * Asterisks indicate residual solvent peaks.
