CETALOX Usage And Synthesis
| 3a,6,6,9a-Tetramethyldodecahydronaphtho[2,1-b]furan is a crystalline autoxidation product of ambrein with a typical ambergris odor. It is prepared from (?)-sclareol, a diterpene alcohol obtained from extraction of clary sage plants. Oxidative degradation to a lactone (“sclareolide”), hydrogenation of the latter to the corresponding diol, and dehydration yield the title compound. | |
Occurrence | Reported found in clary sage oil. | |
Preparation | Racemic sclareolide can be prepared by cyclization of homofarnesic acid in the presence of SnCl4 as a catalyst . Pure diastereomers are obtained by acid cyclization of (E)- and (Z)-4-methyl-6-(2,6,6-trimethylcyclohex-l(2)-enyl)-3- hexen-1-ol, prepared from 2-methyl-4-(2,6,6-trimethylcyclohex-l(2)-enyl)-2- butenal [394]. If the racemic sclareolide mixture is resolved into its enantiomers, the (–)-oxide may also be obtained by a totally synthetic route | |
