Problems solved by technology

Although the above products all have the characteristics of sandalwood-type spices, they still cannot replace the charm of natural sandalwood, mainly because they lack the unique traces of sandalwood aldehydes in the sandalwood extract.
[0006] However, the content of sandalaldehyde in the natural sandalwood extract is extremely small, and it is difficult to meet the needs of industrialization
So far, there is no process route for synthesizing this raw material in China

Embodiment 1

[0030] (1) At a room temperature of 20° C., 10 g of santalol and 250 g of n-hexane were fully mixed. Then add manganese dioxide as a catalyst, stir and mix thoroughly, turn on the heating device, control the reaction temperature at 40° C., and the reaction time is 48 hours, thereby obtaining mixture A.

[0031] (2) The mixture A obtained in step (1) is filtered, and the catalyst manganese dioxide is separated, and the residue is distilled under reduced pressure at 45°C and 0.9MPa, and concentrated to obtain an oily product, which is then prepared by thin-layer chromatography SiO 2 , thickness: 2 millimeters; Eluent: hexane: ethyl acetate=9: 1; Eluent flow rate: 6 milliliters / minute; Separation time: 30-40 minute; Carry out refining under the condition of 200mL eluent, obtain 9.12 g of product B.

[0032] (3) 9.12g of product B obtained in step (2) was dissolved in 95g of chloroform. At the same time, 1 g of glacial acetic acid was added to the above solution. Then, under t...
