The Relation of Structure and Odor in Substituted Cyclohexanols

All of the current theories lack a biochemical foundation and knowledge of the true geometry of the receptor site in the olfactory bulbus. This and a still unexplained fact that not only diverse chemical structures but also analogues of a similar basic structure sometimes smell quite differently is one of tbe reasons we still need more information about the correlations between different chemical structures and their odor perceptions.

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.
