Figure 4: The 13C solid-state NMR spectra of the S-enantiomer of binol (S-4): an aged sample after cocondensation with sucrose from DSMO solution (trace a), a freshly dried sample after cocondensation (trace b), a physically mixed-only sample of S-enantiomer (S-4) and sucrose, ca. 1 : 1 (trace c), and the pure S-enantiomer (S-4) (trace d).
