Method for synthesizing beta-damascenone

The invention discloses a method for synthesizing beta-damascenone. The method mainly comprises the following steps: oxidizing citral through sodium chlorite; carrying out catalytic cyclization through concentrated phosphoric acid to obtain alpha-cyclogeranic acid; eliminating the alkalinity of the alpha-cyclogeranic acid under the action of thionyl chloride to obtain cyclogeranenone; carrying outaddition on the cyclogeranenone and allylmagnesium chloride and carrying out acidic isomerization to obtain alpha-damascenone; carrying out epoxidation on the alpha-damascenon through peroxyacetic acid, and carrying out alkaline ring opening through potassium carbonate; catalytically heating and dehydrating through para-toluenesulfonic acid to obtain the beta-damascenone. The method disclosed bythe invention has the advantages that raw materials are cheap and easy to obtain, reaction conditions are moderate and the operation is simple and convenient; another useful spice alpha-damascenone can be synchronously synthesized and the method is a method which is suitable for industrial production of the beta-damascenone.
