TL;DR: The temperature-dependent 1H n.m.r. spectra of suitably substituted disalicylides, related lactones, and bislactams demonstrate their ring inversion (B ⇌ B*) between enantiomeric boat conformations.
Abstract: The temperature-dependent 1H n.m.r. spectra of suitably substituted disalicylides [(3) and (4)], related lactones [(8) and (9)], and bislactams [(10) and (11)], demonstrate their ring inversion (B ⇌ B*) between enantiomeric boat conformations.

TL;DR: The temperature dependence of the 1H n.m.r. spectrum of 1,4,7,10,13,16-hexamethyl-5,6,11,12,17,18-hexahydrotribenzo[a,e,i]cyclododecaene (2) has been interpreted in terms of ring inversion between enantiomeric C2 conformations as mentioned in this paper.
