  Asymmetric synthesis of (+)-chloriolide

  摘要：

  An asymmetric synthesis of 12-membered ring macrolide, chloriolide has been accomplished by adopting a linear strategy. Lipase-catalyzed enzymatic kinetic resolution (EKR), asymmetric alkynylation using Trost pro-phenol catalyst followed by Yamaguchi macrolactonization has been successfully employed to achieve the target molecule.

• Preparation of Enantioenriched Alkylcarbastannatranes via Nucleophilic Inversion of Alkyl Mesylates for Use in Stereospecific Cross-Coupling Reactions
  作者：Glenn Ralph、Mark R. Biscoe

  DOI：10.1021/acs.organomet.9b00467

  日期：2019.10.28

  We report the preparation of enantioenriched secondary alkylcarbastannatranes via a stereoinvertive SN2 reaction of enantioenriched alkyl mesylates and carbastannatranyl anion equivalents. Using this process, enantioenriched secondary alcohols may be converted into highly enantioenriched alkylcarbastannatranes, which are useful in stereospecific cross-coupling reactions.

  我们报告了通过对映体富集的烷基甲磺酸盐和碳原子化炔基阴离子等价物的立体转化S N 2反应制备对映体富集的仲烷基氨基甲酸酯。使用该方法，可以将对映体富集的仲醇转化为高度对映体富集的烷基碳黄烷烃，其可用于立体有择的交叉偶联反应中。
• Stereospecific Electrophilic Fluorination of Alkylcarbastannatrane Reagents

  DOI：10.1002/anie.201704672

  日期：2017.10.2

  Speed matters: Site-specific fluorination reactions of isolable primary and secondary alkylcarbastannatrane nucleophiles occur fast, without the need for transition metal catalysis, or in situ activation of the nucleophile. The reaction conditions can also be extended to stereospecific chlorination, bromination, and iodination reactions.

  速度很重要：可分离的伯烷基氨基甲酸酯和仲烷基亲核试剂亲核的特定位置的氟化反应快速发生，而无需过渡金属催化或亲核分子的原位活化。反应条件还可以扩展到立体定向氯化，溴化和碘化反应。
• Barbier-Negishi Coupling of Secondary Alkyl Bromides with Aryl and Alkenyl Triflates and Nonaflates
  作者：Ke-Feng Zhang、Fadri Christoffel、Olivier Baudoin

  DOI：10.1002/anie.201711990

  日期：2018.2.12

  secondary alkyl bromides with aryl and alkenyl triflates and nonaflates has been developed. This challenging reaction was enabled by the use of a very bulky imidazole‐based phosphine ligand, which resulted in good yields as well as good chemo‐ and site selectivities for a broad range of substrates at room temperature and under non‐aqueous conditions. This reaction was extended to primary alkyl bromides

  已经开发出温和而实用的仲烷基溴化物与芳基和烯基三氟甲磺酸酯和壬二酸酯的Barbier-Negishi偶联。通过使用非常庞大的咪唑基膦配体，可以实现这一具有挑战性的反应，从而在室温下和非水条件下对多种底物产生了良好的收率以及良好的化学和位点选择性。通过使用类似的吡唑基配体，该反应扩展为伯烷基溴化物。
