  Electrophilic Fluorodesilylation of Allenylmethylsilanes:  A Novel Entry to 2-Fluoro-1,3-dienes

  摘要：

  Various fluorodienes were prepared by treatment of the corresponding allenylmethylsilanes with Selectfluor. This is the first route to these compounds not based on the use of a fluorinated building block. The reaction allows the preparation of 2-fluoro-1,3-dienes with several substitution patterns, including di- and trisubstituted compounds.

  Tandem Zn‐Brook Rearrangement/Ene‐Allene Carbocyclization

  摘要：

  AbstractThe addition of metalated alkynes to acylsilanes leads to the corresponding α‐propargylsilanol derivatives. On addition of ZnBr2, Zn‐promoted Brook rearrangements take place to produce the propargyl/allenylzinc bromides, which undergo cyclization to give functionalized carbocycles as single diastereoisomers.

  The direct formation of aryl C−O bonds via the intramolecular dehydrogenative coupling of a C−H bond and a pendant alcohol represents a powerful synthetic transformation. Herein, we report a method for intramolecular arene C−H etherification via an umpoled alcohol cyclization mediated by an I(III) N-HVI reagent. This approach provides access to functionalized chromane scaffolds from primary, secondary

  通过C-H键和侧醇的分子内脱氢偶联直接形成芳基C-O键代表了强大的合成转化。在此，我们报告了一种通过 I(III) N- HVI 试剂介导的 umpoled 醇环化进行分子内芳烃 C-H 醚化的方法。这种方法通过级联环化-碘盐形成从伯醇、仲醇和叔醇中获得官能化色满支架，后者为下游衍生化提供了通用的功能处理。计算研究支持通过 I(III) 配体交换初始形成 umpoled O-中间体，然后是竞争性直接和螺环化/1,2-转变途径。

  α-difluoromethylene alkyne as a nontraditional one-carbon reaction partner, a synthetically novel method for the construction of isoindolin-1-one derivatives via Rh(III)-catalyzed [4+1] annulation reaction is reported. The 2-fold C-F bond cleavage not only enables the generation of desired product under an overall oxidant-free condition but also results in a net migration of carbon-carbon triple bond. In addition

  使用 α,α-二氟亚甲基炔作为非传统的单碳反应伙伴，报道了一种通过 Rh(III) 催化的 [4+1] 环化反应构建异吲哚啉-1-one 衍生物的合成新方法。2 倍 CF 键断裂不仅能够在整体无氧化剂的条件下生成所需的产物，而且还会导致碳-碳三键的净迁移。此外，由于采用了温和的反应条件，本反应方案对广泛的官能团具有耐受性。
• Asymmetric transfer hydrogenation of unsaturated ketones; factors influencing 1,4- vs 1,2- regio- and enantioselectivity, and alkene vs alkyne directing effects

  A detailed study has been completed on the asymmetric transfer hydrogenation (ATH) of a series of enones using Ru(II) catalysts. Electron-rich rings adjacent to the CO group reduce the level of CO reduction compared to CC. The ATH reaction can readily discriminate between double and triple bonds adjacent to ketones, reducing the double bond but leaving a triple bond intact in the major product.

  使用Ru（II）催化剂对一系列烯类的不对称转移氢化（ATH）进行了详细的研究。与C C相比，与C O基团相邻的富电子环降低了C O的还原水平。ATH反应可以轻松区分与酮相邻的双键和三键，还原双键，但在主链中保留完整的三键。产品。

  A general solution for the synthesis of various oxetan-3-ones is developed. This reaction uses readily available propargylic alcohols as substrates and proceeds without the exclusion of moisture or air ("open flask"). Notably, oxetan-3-one, a highly valuable substrate for drug discovery, can be prepared in one step from propargyl alcohol in a fairly good yield. The facile formation of the strained
