| Abstract | An X-ray structure analysis shows that the 5, 18-dimethyl derivative (5) of the title compound (4) crystallises from xylene as a 1:1 inclusion compound in which the host molecules adopt propeller-like conformations (7 and 7*) with almost perfect C2 symmetry. Dynamic 1H n.m.r. spectroscopy shows that the 5, 18-dibenzyl derivative (6) of (4) forms a 1:1 inclusion compound with ethanol in the solid state and undergoes ring inversion (7 ⇌ 7*) between enantiomeric propeller-like conformations in solution against a barrier of 21.1 kcal mol-1. © 1981. |
