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.

Synthesis and odor characteristics of some 6,6-dimethylbicyclo [3.1.0] hexane derivatives

It can be generally stated that the odor of the compound group under investigation, containing 8-10 carbon atoms in the molecule, is strongly influenced by the 6,6-dimethylbicyclo[3.10]hexane system which decides their common characteristic camphoric-penetrating odor.
