Paragraph 0007; 0013, (2017/08/27)
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.

A strategy for the allylic oxidation of cyclic alkenes with a copper-aluminum mixed oxide as catalyst is presented. The reaction involves the treatment of an alkene with a carboxylic acid employing tert-butyl hydroperoxide as the oxidant. In all cases, the corresponding allylic esters are obtained. When l-proline is employed, the allylic alcohol or ketone is obtained. The oxidation of cyclohexene and valencene has been optimized by design of experiments (DoE) statistical methodology.
