| Hazard Information | Back Directory | [Chemical Properties]
Dodecahydro-3,8,8,11a-tetramethyl-5H-3,5a-epoxynaphth[2,1-c]oxepin is a colorless to pale yellow liquid. It possesses a powerful
amber note with good stability in nonaggressive media. | [Preparation]
The synthesis starts from the natural raw material manool, which is obtained by
extraction from a tree growing in New Zealand, the so-called pink pine, Halocarpus
biformis (Hooker) C.J. Quinn. Epoxidation of manool, subsequent oxidative
degradation of the allylalcohol side chain to yield a ketone, and intramolecular
acetalization afford the ketal. | [Trade name]
