  Synthesis of optically active heterocyclic compounds via deracemization of 1,2-diol monotosylate derivatives bearing a long aliphatic chain by a combination of enzymatic hydrolysis with Mitsunobu inversion

  摘要：

  We have succeeded in accomplishing the deracemization of (+/-)-2-acetoxydecyl and (+/-)-acetoxy-6-benzyloxyhexyl tosylates, which have a long substituent, via an enzyme-mediated enantioselective hydrolysis with a Mitsunobu inversion using polymer-supported triphenylphosphine to afford the corresponding (S)-enantiomer. Enantiomerically pure (S)- and (R)-gamma-dodecalactones, a fruit flavor, were synthesized from (S)-2-acetoxydecyl tosylate as the mutual starting material. The poisonous alkaloid (S)-coniine was also synthesized using enantiomerically pure allyl amine as the key intermediate derived from (S)-acetoxy-6-benzyloxyhexyl tosylate. (C) 2012 Elsevier Ltd.

  Chiral Ti salalen complexes catalyze the asymmetric epoxidation of terminal non‐conjugated olefins with hydrogen peroxide. Modular ligands based on cis‐1,2‐diamino‐cyclohexane (cis‐DACH) were developed, giving high yields and enantiomeric excesses (ee, up to 96 %) at catalyst loadings as low as 0.1–0.5 mol %, and even under solvent‐free conditions.

  手性Ti Salalen配合物催化过氧化氢催化末端非共轭烯烃的不对称环氧化。开发了基于顺式1,2-二氨基环己烷（cis - DACH）的模块化配体，在催化剂负载量低至0.1-0.5 mol％甚至更低的情况下，可提供高收率和对映体过量（ee，高达96％）无溶剂条件。

  Help for the neglected: Terminal, non‐conjugated olefins, such as 1‐octene, are difficult to epoxidize asymmetrically. Ti salalen complexes based on cis‐1,2‐diaminocyclohexane catalyze this demanding reaction giving high yields and enantioselectivities (up to 95 % ee), with H2O2 as the oxidant. The X‐ray structures of the μ‐oxo and peroxo complexes shed light on the coordination behavior of this novel

  被忽视的帮助：末端非共轭烯烃（例如1-辛烯）难以不对称环氧化。基于顺式1,2-二氨基环己烷的Ti salalen络合物以H 2 O 2为氧化剂，可催化要求苛刻的反应，从而提供高收率和对映选择性（最高95％  ee）。μ-oxo和peroxo配合物的X射线结构阐明了这类新型配体的配位行为。
