  A complementary method to obtain N-acyl enamides using the Heck reaction: extending the substrate scope for asymmetric hydrogenation

  摘要：

  A method to prepare N-acyl enamides is reported that is complementary to the existing protocols. Heck reaction of a variety of aryl trifluoromethanesulfonates with commercially available N-vinylacetamide occurred in a highly regioselective fashion to provide these valuable synthetic intermediates. This method permits the formation of N-acyl enamides containing functionality that would not be tolerated by the existing methods. Asymmetric hydrogenation using [diphosphine RhCOD]BF4 complexes provided optically active protected amines in up to 99% ee. De-acylation occurs without affecting the amine enantiopurity.

• Cyclohexylamine oxidase as a useful biocatalyst for the kinetic resolution and dereacemization of amines

  日期：2012.1

  The biocatalytic performance of a cloned cyclohexylamine oxidase derived from Brevibacterium oxydans IH-35A towards structurally different amines was investigated. Cycloalkyl primary amines, alkyl aryl amines, and α-carbon-substituted aliphatic amines were identified as suitable substrates for the biocatalyst based on an activity assay. Kinetic resolutions of several amines by either recombinant whole cells or crude enzyme extracts prepared therefrom gave enantiomerically pure (R)-amines besides the corresponding ketones. When cyclohexylamine oxidase in combination with a borane–ammonia complex as reducing agent was applied to the deracemization of several substrates, excellent enantiomeric ratios (>99:1) and good isolated yields (62%–75%) of the corresponding (R)-amines were obtained.

  从Brevibacterium oxydans IH-35A中克隆的环己胺氧化酶的生物催化性能对结构不同的胺进行了研究。基于活性测定，环烷基初级胺，烷基芳基胺和α-碳取代脂肪胺被确定为生物催化剂的合适底物。通过重组整细胞或制备的粗酶提取物对几种胺进行动力学分辨，除了相应的酮外，得到了对映纯的(R)-胺。当将环己胺氧化酶与硼氨复合物作为还原剂应用于几种底物的去消旋作用时，获得了优异的对映比（>99:1）和相应(R)-胺的良好分离收率（62%–75%）。

  was developed to obtain chiral β-amino acid esters with lipase B from Candida antarctica (CAL-B) as the only catalyst. This method is conducted under mild reaction conditions and is very easy to handle. After a series of detailed optimization studies, ten racemic aromatic or aliphatic amines were subjected to this one-pot procedure, and twelve chiral β-amino acid esters and ten chiral amides were successfully

  Highly enantiopure (1-aryl)- and (1-naphthyl)-1-ethylamines were synthesized by the borane-mediated reduction of single-isomeric (E)- and (Z)-O-benzyloxime ethers using the stable spiroborate ester derived from (S)-diphenyl valinol and ethylene glycol as the chiral catalyst. Primary (R)-arylethylamines were prepared by the reduction of pure (Z)-ethanone oxime ethers in up to 99% ee using 15% of catalyst

  stereoselective amination of (hetero)aromatic ketones using transaminases have been studied, such as temperature, pH, substrate concentration, cosolvent, and source and percentage of amino donor, to further optimize the production of enantiopure amines using both (S)- and (R)-selective biocatalysts from commercial suppliers. Interesting enantiopure amino building blocks have been obtained, overcoming some limitations
