Synthesis and Odor Characteristics of New Gem-Dimethylcyclohexane Derivatives

Searching for cyclic analogs of the insect juvenile hormones, we synthesized a series of new compounds containing the cyclogeraniolene system. This system can be considered as a cyclic form of acyclic terpenes, such as dihydrocitronellol, dihydrogeraniol, and menthocitronellol. The isoprenoid chain in these compounds is rolled to form the cyclohexane ring by connection of the carbon atoms C-7 and C-10. As compared with the classical cyclic systems of the cyclogeraniol type, the compounds obtained by us contain the gem-dimethyl groups in the 3-position in relation to a chain with the functional group.

Cycloheptadecanone from Dimethyl Octadecanedioate via a One-Step Catalytic Process

Although the reaction was not studied, it does establish that a one-step conversion of the long chain diesters to the cyclic ketone containing one less carbon atom can occur. It opens the possibility to simpler processes for the preparation of macrocyclic ketones.

3-Cyclohexylpropanal and 3-Cyclohexylbutanal as Raw Materials for Fragrant Compounds

This study reports an investigation of the hydrogenation of aromatic rings of these alcohols, leading to the respective 3-cyclohexyl-1-alkanols.

Acetals and Ketals of 3β, 4β-caranediol-New Odoriferous Compounds from (+)-3-carene

In summary, it is noteworthy that the odor characteristics of acetals and ketals of bicyclic terpenic diols have been absent in the literature. Our discovery of interesting odors of ketals of (+)-3β,4β-caranediol indicates further potential possibilities of synthesis of new odoriferous compounds in the series of bicyclic terpenic diols.

Fragrant Esters of 3-Cyclohexylbutanoic Acid

Thus, the acid is not too easily available, but remarkable fragrant properties of its esters raise the interest in its production. The first four stages of its synthesis have been described previously. Prin’s reaction of α-methylstyrene with formaldehyde yields 4-methyl-4-phenyl-1,3-dioxane.
