a 19F NMR spectra (C6D6, 300 K, 471 MHz) for the time-course analysis for the formation of (SZn)-[ZnL((S)-dpp)]. Conditions: rac-[Zn2L2] + (S)-dpp (2.50 equiv.); dry MS4A; C6D6; 4.00 mM; 70 °C; (1) 0 h, (2) 0.5 h, (3) 48 h. b Time-course variation of diastereomeric excess calculated from 19F NMR in various conditions. Conditions: rac-[Zn2L2] + (S)-dpp or (S)-mdp (2.50 or 1.00 equiv.), dry MS4A, C6D6, 4.00 mM, 70 °C. c The structure of (S)-mdp.
