• Hydrogenolysis of 4,4-dimethyltricyclo[6.3.0.0<SUP>1,7</SUP>]undecane-2,6-dione with a Pd-C catalyst gave <I>cis</I>-4,4-dimethylbicyclo[6.3.0]undecane-2,6-dione and 8,8-dimethylspiro[4.6]undecane-6,10-dione. The <I>cis</I> isomer has been shown to isomerize almost completely to the <I>trans</I> isomer under acidic and basic conditions.
