%X The thermodynamic parameters for equilibration of the chair-chair conformational enantiomorphs of cis-10-methyl-9-decalol (1) and (2) have been determined as EA 69.8 ± 0.9 kJ mol-1, &#916;H? 66.7 ± 1.3 kJ mol-1 and &#916;S? + 12 ± 5 JK-1 mol-1. For cis-10-methyl-1-decalone, conformer (3) is 1.25 kJ mol-1 more stable at 200 K than conformer (4) with EA 42.9 ± 0.7 kJ mol-1, &#916;H? 41 .0 ± 0.7 kJ mol-1 and &#916;S? -20 ± 3J K-1 mol-1 for the conversion of (3) + (4. The c.m.r. spectra of these com- pounds, together with those for the coprostan-4-one and coprostan-6-one, have been assigned.
