• The addition to the methyl-substituted 4-<I>t</I>-butylcyclohexanone was studied, providing that the β-axial methyl and α-axial methyl groups hindered the axial and equatorial attacks respectively. The results obtained with fused-ring system ketones (four decalones) were explained by considering the similar stereochemical influence of 2-and 3-methylene substituents as corresponding methyl substituents. A rapid conformation equilibrium was also considered for <I>cis</I>-decalones. In addition, the axial attack, especially at a molar ratio of two or more, was found to be hindered by the α-equatorial methyl group. This hindrance was explained by assuming the half-chair form of the cyclohexanone ring in the transition state.
