実験手順

To trans 1-(2,6,6-trimethyl-3-cyclohexen-1-yl)-2-buten-1-one (25 g; 130 mmol; trans:cis 98:2; purity≧99%) stirred under nitrogen at 20° C. was added BF3.(AcOH)2 (0.65 mmol) and [Ru(COD)(methallyl)2] (0.65 mmol) are added consecutively. The resulting solution was heated to 130° C. and stirred over 60 minutes at 130° C. under nitrogen. Then the resulting mixture is cooled to 20° C. and there was obtained a mixture comprising (% by weight of the final mixture, obtained by GC analysis):
