+-Nootkatone derivative

The invention discloses a preparation method for +-nootkatone derivative. The present invention uses the +-nootkatone derivative extracted from cedar leaves as the main material, a chemical compound II is obtained after the restoration through sodium borohydride, the chemical compound II reacts to obtain a chemical compound III and a chemical compound IV through the decomposition of enzymatic dynamics, or decomposes through dynamic kinetics to obtain a chemical compound III with more than 90% yield, a chemical compound V is obtained after hydrolyzing the chemical compound III. The present invention turns the latent chiral ketone group in +-nootkatone into a chirality hydroxy center, and splits further; the present invention has the characteristics of being simple in operation, being high in product yield and with good optics purity.

Biotransformation of citrus aromatics nootkatone and valencene by microorganisms

Biotransformations of the sesquiterpene ketone nootkatone (1) from the crude drug Alpiniae Fructus and grapefruit oil, and the sesquiterpene hydrocarbon valencene (2) from Valencia orange oil were carried out with microorganisms such as Aspergillus niger, Botryosphaeria dothidea, and Fusarium culmorum to afford structurally interesting metabolites. Their stereostructures were established by a combination of high-resolution NMR spectral and X-ray crystallographic analysis and chemical reaction. Metabolic pathways of compounds 1 and 2 by A. niger are proposed.

The Preparation and Microbiological Hydroxylation of the Sesquiterpenoid Nootkatone

The sesquiterpenoid nootkatone has been prepared from valencene by copper(I) iodide catalysed oxidation with t-butylhydroperoxide and hydroxylated at C-9 by Mucor plumbeus and Cephalosporium aphidicola.
