Vapor-phase Hydration of Dicyclopentadiene Catalyzed by Niobic Acid

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.

Enantioselectivity in odor perception synthesis and olfactory properties of the new tricyclic sandalwood odorant Fleursandol

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.

Synthesis and Reactions of Tricyclic Monocarboxylic Acid Esters

A convenient and efficient method for preparing tricyclic esters has been developed on the basis of addition of C1-C3 monocarboxylic acids to tricyclo2,6>deca-3,8-diene and its dimethyl derivatives in the presence of p-toluenesulfonic acid.The orientation of the ester group in the products has been determined.Some reactions of the resulting esters have been studied, and their possible applications have been proposed.
