The conformational behaviour of 5,6,11,12,17,18-hexahydrotribenzo[a,e,i]-cyclododecaene and its derivatives
Abstract
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.
