Page/Page column 4-6, (2019/07/04)
The invention relates to a method of preparing tricyclic decenol, a reaction intermediate and a preparation method of the reaction intermediate. The preparation method of tricyclic decenol comprises the steps of allowing dicyclopentadiene and trifluoroacetic acid to give an addition reaction to form tricyclodecenyl trifluoroacetate, and performing hydrolysis through potassium carbonate to form tricyclic decenol. The preparation method is low in reaction temperature, short in time, and environmentally friendly; the quantity of reaction pollutants is small; a yield of a tricyclic decenol productcan reach 94%; and at the same time, the purity of tricyclic decenol can reach 98%.

The 3-methyl-4-(tricyclo[5.2.1.02,6]dec-4-en-8-ylidene)butan-2- ols (=Fleursandol; rac-10), a new class of sandalwood odorants, were synthesized in their enantiomerically pure forms by use of tricyclo[5.2.1.0 2,6]dec-4-en-8-ones 17 and ent-17 and (tetrahydro-2H-pyran-2-yl)- protected 4-bromo-3-methylbutan-2-ols 22 and ent-22 as starting materials (Schemes 2-4). Only four of 16 possible stereoisomers of rac-10 possess the typical, very pleasant, long-lasting sandalwood odor (Table 1). The (2S,3R,4E,1′R,2′R,6′R,7′R)-isomer ent-10a is by far the most important representative, with an odor threshold of 5 μg/l in H 2O.

Vapor-phase hydration of dicyclopentadiene in a flow system was promoted by niobic acid.Maximum conversion to the hydrated product was obtained at around the boiling point of dicyclopentadiene, 170 deg C.Niobic acid rapidly decreased its catalytic activity when it was heat-treated at temperatures higher than 300 deg C.
