  The studies on chemoenzymatic synthesis of Femoxetine

  摘要：

  The studies on enzymatic kinetic resolution of 3-phenyl-4-pentenoic acid esters were performed. The obtained results demonstrated that the careful choice of biocatalyst and a reaction type are very important for successful enzymatic kinetic resolution. Kinetic resolution provides 3-phenyl-4-pentenoic acid (1) with good enantioselectivity upon esterification. That product was used as a substrate for formal synthesis of two biologically relevant compounds Femoxetine and LG 121071. (C) 2012 Elsevier B.V. All rights reserved.

• A Sequential Acyl Thiol–Ene and Thiolactonization Approach for the Synthesis of δ-Thiolactones
  作者：Ruairí O. McCourt、Eoin M. Scanlan

  日期：2019.5.3

  A novel strategy for the synthesis of δ-thiolactones from inexpensive and readily available γ-unsaturated esters has been developed. This strategy incorporates a radical acyl thiol–ene reaction as the key C–S bond forming step. Cyclization is achieved via a Steglich-type thiolactonization of 5-mercaptopentanoic acids. We report the facile and scalable synthesis of δ-thiolactones in moderate to good

  已开发出一种从廉价且容易获得的γ-不饱和酯合成δ-硫代内酯的新策略。该策略将自由基酰基硫醇-烯反应纳入了关键的CS键形成步骤。通过5-巯基戊酸的Steglicch型硫内酯化来实现环化。我们报道了在温和的反应条件下，对中等官能团具有良好的收率的δ-硫代内酯的简便，可扩展合成，对一系列官能团具有耐受性。

  Sweet cyclizations: The synthesis of pyrrolizidines and indolizidines has been achieved. Olefins were subjected to an intramolecular palladium‐catalyzed aminoalkynylation with the hypervalent iodine reagent TIPS‐EBX. After removal of the protecting group, a two‐step cyclization sequence and subsequent reduction led to the natural product (±)‐trachelanthamidine (see scheme; TIPS‐EBX=triisopropylsilyl

  hydrothiolation of alkenes (and alkyne) is reported. A variety of sulfur containing motifs including alkanethiols, thiophenols and thioacids undergo an atmospheric oxygen‐mediated radical hydrothiolation reaction with a plethora of alkenes in good yield with excellent functional group compatibility, typically with short reaction times to furnish a range of functionalized products. Biomolecules proved

  据报道，烯烃（和炔烃）具有轻度，无金属，大气氧介导的自由基氢硫醇化作用。包括链烷硫醇，硫酚和硫代酸在内的各种含硫基序与大量烯烃进行大气氧介导的自由基氢硫醇化反应，收率高，具有出色的官能团相容性，通常反应时间短，可提供一系列官能化产物。事实证明，生物分子可以耐受这些条件，并且该过程坚固且易于执行，无需专用设备。简洁的机理研究证实了该过程是通过硫醇烯反应歧管中的自由基中间体进行的。
