To trans 1-(2,6,6-trimethyl-3-cyclohexen-1-yl)-1-ethanone (4.52 mol; trans/cis=94/5 to 99/1, purity≧99%) stirred under nitrogen at 20° C. was added BF3.(AcOH)2 (2.27 mmol of BF3) and [Ru(COD)(methallyl)2] (2.27 mmol) was added consecutively. The resulting solution was heated to 130° C. and stirred over 30 minutes at 130° C. under nitrogen. Afterwards, the resulting mixture was cooled to 20° C. and there was obtained a mixture comprising (% by weight of the final mixture, obtained by GC analysis):
