    摘要: The present invention relates to novel poly-alkylated benzodioxin compounds possessing a musk-like aroma which are useful as fragrance materials. The compounds of the invention have the formula: ##STR1## where R.sup.1 to R.sup.4 are hydrogen or lower alkyl (C.sub.1 to C.sub.5), provided that the compound has no more than 18 carbon atoms. The invention provides for synthesis of a novel phenolic intermediate and synthesis of the compounds of the invention. The invention also provides fragrance compositions which utilize the compounds of the invention to modify, enhance, or impart a musk-like aroma to perfume compositions, colognes and perfumed articles.

    摘要: A method of producing nootkatone by laccase catalyzed oxidation of valencene. Valencene and a composition having laccase activity are reacted in the presence of an oxygen source, at a valencene concentration greater than 0.1%, to form valencene hydroperoxide. Optionally, a mediator and/or a solvent at a concentration that maintains laccase activity may also be included. The valencene hydroperoxide is degraded to form nootkatone, and nootkatone is then recovered. The method produces nootkatone in commercially viable yields.
