Synthesis and odor of optically active trans-2,2,6-trimethylcyclohexyl methyl ketones and their related compounds

The synthesis characterized by cationic olefin cyclizations accomplished using ketone enol esters and odor of novel (1R,6S)- and (1S,6R)-2,2,6-trimethylcyclohexyl methyl ketones (5) are described. The stereoselective syntheses of (E)-(1R,6S)- and (E)-(1S,6R)-1-(2,2,6-trimethylcyclohexyl)-2-buten-1-one (6) and (1R,6S)-ethyl 2,2,6-trimethylcyclohexylcarboxylate (7), useful raw materials for flavor and fragrance, starting from the (1R,6S)- and (1S,6R)-5 are also described.

Isomer composition containing optically active ethyl trans-2,2,6-trimethylcyclohexylcarboxylate and fragrance composition containing the isomer composition

A geometrical isomer composition excellent in odor and in chemical resistance, which is applicable to a base material containing a strongly alkaline chemical or a strongly acidic chemical, which can suppress the deterioration with time and the color change of the base material in the case that the material is exposed to light, and which also have highly palatable and unique fruity floral fragrance. The composition is produced by mixing 93 to 99% by weight of optically active ethyl trans-2,2,6-trimethylcyclohexylcarboxylate represented by Formula-1 or a mixture thereof and 7 to 1% by weight of optically active ethyl cis-2,2,6-trimethylcyclohexylcarboxylate represented by Formula-2 or a mixture thereof, respectively.
