  New Synthesis of 3-Aryl-2,5-dihydrofurans

  摘要：

  We present a straightforward synthesis of 3-aryl-2,5-dihydrofurans by ring contraction of 4-aryl-3,6-dihydro-2H-pyrans with the repeated treatment of MCPBA and BF3-OEt2. The building block 3-aryltetrahydrofuran-3-carboxylic acid with potential biological activities was also prepared.

• Reductive Carbocyclization of Homoallylic Alcohols to <i>syn</i> -Cyclobutanes by a Boron-Catalyzed Dual Ring-Closing Pathway

  carbocyclization of homoallylic alcohols has been developed by using hydrosilanes as reducing reagents to provide a range of 1,2‐disubstituted arylcyclobutanes. The reaction proceeds in a cis‐selective manner with high efficiency under mild conditions. Mechanistic studies, including deuterium scrambling and Hammett studies, and DFT calculations, suggest a dual ring‐closing pathway.

  通过使用氢硅烷作为还原剂，提供了一系列1,2-二取代的芳基环丁烷，已经开发出有机硼烷催化的均烯丙醇还原性碳环化反应。在温和条件下，反应以顺式选择方式高效进行。包括氘加扰和Hammett研究在内的机理研究以及DFT计算均提出了双闭环途径。

  Current synthesis of alpha-substituted 3,6-dihydro-2H-pyrans dominantly relies on functional group transformation. Herein, a direct and practical oxidative C-H alkynylation and alkenylation of 3,6-dihydro-2H-pyran skeletons with a range of potassium trifluoroborates is developed. The metal-free process is well tolerated with a wide variety of 3,6-dihydro-2H-pyrans, rapidly providing a library of 2,4-disubstituted 3,6-dihydro-2H-pyrans with diverse patterns of alpha-functionalities for further diversification and bioactive small molecule identification.
