• Synthesis of α-Quaternary Formimides and Aldehydes through Umpolung Asymmetric Copper Catalysis with Isocyanides
  作者：Kentaro Hojoh、Hirohisa Ohmiya、Masaya Sawamura

  日期：2017.2.15

  A highly regio- and enantioselective copper-catalyzed three-component coupling of isocyanides, hydrosilanes, and γ,γ-disubstituted allylic phosphates/chlorides to afford chiral α-quaternary formimides was enabled by the combined use of our original chiral naphthol-carbene ligand as a functional Cu-supporting ligand and LiOtBu as a stoichiometric Lewis base for Si. The formimides were readily converted

  A practical stereoselective synthesis of (S)-bakuchiol (1) and its enantiomer is reported. The important intermediate, (R)-configured β-siloxy aldehyde 5, was obtained in three steps from the easily available material geraniol (2) via the key step of Yamamoto's rearrangement of epoxy silyl ethers. (S)-Bakuchiol (1) and its enantiomer, (R)-bakuchiol (17), were finally obtained in different synthetic

  Linalool synthase variants are disclosed. The variants preferably comprise an amino acid sequence having one or more amino acid substitutions. Variants producing a greater linalool yield and/or higher linalool:nerolidol ratio compared with the corresponding wild type linalool synthase are also disclosed. A method comprising the conversion of geranyl pyrophosphate to linalool using a linalool synthase variant is also disclosed.
