Description

technical field

[0001] The invention relates to a synthesis method and application of an unsaturated enone compound, that is, a synthesis method and application of nokadone. Background technique

[0002] Nokadone (5,6-dimethyl-8-isopropylbicyclo[4,4,0]dec-1-en-3-one), also known as narone, belongs to Eremophillane ) is an unsaturated enone of the bicyclic sesquiterpenes. It was discovered in the 1960s from Alaska cork (Chamaecyparis nootkatensis) oil and grapefruit peel oil, and its unique structure was identified. Nokatone has a sharp aroma, but it is an important aroma component in grapefruit peel and grapefruit juice, and it can enhance the aroma and taste of grapefruit in essence. It has been isolated from natural essential oils for many years, but because of its low content in natural essential oils, it is difficult to separate and its usage is limited.
