Preparation method of ambrotone for improving fragrance quality of ambergris

The invention provides a preparation method of ambrotone for improving fragrance quality of ambergris. The method comprises the following steps: (1) 3-methyl-3-penten-2-ketone is synthesized; (2) an intermediate product cyclic ketone is obtained by a Diels-Alder reaction; (3) a cyclization reaction is carried out, wherein a certain amount of strong acids and lower alcohol solvents are added into a reaction vessel, the raw material intermediate product cyclic ketone is added drop by drop at a certain temperature, the reaction is carried with stirring for 5-10 hour, and the product ambrotone is obtained. Compared with the prior art, the method is advantageous in that content of an ambargris fragrance compound 1-(1,2,3,4,5,6,7,8a-octahydro-1,2,8,8-tetramethyl-2-acetonaphthone) with lower fragrance threshold value is increased from 2% to 5% or above, finally ambargris fragrance of the ambrotone product is improved; nearly no pollution generates in the production process, the yield is high, and the method is suitable for industrial production.
