标题:Method for biocatalytic production of terpene compounds
发明人：SCHALK MICHEL; ROCCI Letizia; SOLIS ESCALANTE DANIEL
权利人:FIRMENICH & CIE
摘要:Provided herein are biocatalytic methods of producing terpene compounds by applying a novel type of phosphatase enzyme. The method allows the fully biochemical synthesis of terpene compounds, like for example copalol and labdendiol, and derivatives thereof, which serve as valuable intermediates for the production of perfumery ingredients, such as, for example, ambrox. Also provided are novel fully biochemical multistep processes for the production of such compounds as well as novel phosphatase enzymes and mutants and variants derived therefrom.

标 题:Carbonylation of allylic alcohols and synthesis of an ambergris fragrance compound
发明人：CASSEL JONATHAN M; HOAGLAND STEVEN M; RENGA JAMES M
权利人:HENKEL KGAA
摘要:A process for the carbonylation of allylic alcohols such as nerolidol, farnesol, or their monocyclic analogues with carbon monoxide at a pressure of at least 30 bar in the presence of a polar solvent and a palladium halide catalyst, optionally an alkali metal halide salt, and optionally an alcoholic solvent. The carbonylated product may then be reduced to the corresponding alcohol, which is cyclized in the presence of Lewis or Br+E,uml o+EE nsted acids to afford an ambergris fragrance compound.

标 题 :Reduction by a silane in the presence of zinc catalyst
发明人：JERPHAGNON THOMAS; PASTORI JOEL
权利人:FIRMENICH & CIE
摘要:The present invention relates to the field of organic synthesis. More specifically, it concerns a process for the selective reduction of a C 3 -C 70 substrate containing one or more carbonyl or carboxylic functional groups into the corresponding 5 alcohol diol, or polyalcohol in the presence of a silane and at least one catalyst or pre-catalyst in the form of a zinc complex. The Zinc complex of formula (I) or (II) is also part of the invention.

标题 :Synthesis and application of chiral substituted polyvinylpyrrolidinones
发明人：HUA DUY H
权利人:UNIV KANSAS STATE
摘要:Chiral polyvinylpyrrolidinone (CSPVP), complexes of CSPVP with a core species, such as a metallic nanocluster catalyst, and enantioselective oxidation reactions utilizing such complexes are disclosed. The CSPVP complexes can be used in asymmetric oxidation of diols, enantioselective oxidation of alkenes, and carbon-carbon bond forming reactions, for example. The CSPVP can also be complexed with biomolecules such as proteins, DNA, and RNA, and used as nanocarriers for siRNA or dsRNA delivery.
