• Transition-Metal-Free Intramolecular Ullmann-Type O-Arylation: Synthesis of Chromone Derivatives
  作者：Jie Zhao、Yufen Zhao、Hua Fu

  DOI：10.1002/anie.201007302

  日期：2011.4.11

  Expect the upexpected: A transition‐metal‐free approach to access chromone derivatives has been developed. The intramolecular O‐arylation of substituted 1‐(2‐haloaryl)‐propane‐1,3‐diones in DMF in the presence of K2CO3 gave the corresponding target products in good to excellent yields (see scheme; DMF=N,N′‐dimethylformamide).

  期望超出预期：已开发出一种无过渡金属的方法来获取色酮衍生物。在存在K 2 CO 3的情况下，在DMF中进行取代的1-（2-卤代芳基）-丙烷-1,3-二酮的分子内O-芳基化反应，相应的目标产物收率良好至优异（参见方案； DMF = N，N'-二甲基甲酰胺）。
• An efficient tandem synthesis of chromones from <i>o</i>-bromoaryl ynones and benzaldehyde oxime

  transition-metal-free strategy was developed for the preparation of chromones from o-bromoaryl ynones and benzaldehyde oxime through sequential C-O bond formation. This cyclization reaction could well tolerate a wide range of functional groups, and the corresponding chromones were given in moderate to excellent yields. Mechanistically, benzaldehyde oxime as a hydroxide source and 1,3-diketone derivatives as reaction

  开发了一种有效的无过渡金属的策略，用于通过顺序形成CO键从邻溴代芳基炔酮和苯甲醛肟制备色酮。该环化反应可以很好地耐受各种官能团，并且相应的色酮以中等至极好的收率给出。从机理上讲，苯甲醛肟是一种氢氧化物源，而1，3-二酮衍生物是反应中间体。
• Reagent-free intramolecular hydrofunctionalization: a regioselective 6-<i>endo-dig</i> cyclization of <i>o</i>-alkynoylphenols

  Solvent-directed intramolecular hydrofunctionalization of readily available o-alkynoylphenols 1 was successfully achieved under reagent-free conditions. The hydrofunctionalization of 1 occurred by nucleophilic attack on the phenolic oxygen followed by consecutive migration of the phenolic H atom to the alkyne center, eventually affording γ-benzopyranones 2. The phenol O–H group forms intramolecular H-bonds

  在无试剂条件下成功实现了容易获得的邻炔基酚1的溶剂导向分子内氢官能化。1的氢官能化通过对酚氧的亲核攻击随后酚氢原子连续迁移到炔烃中心而发生，最终得到 γ-苯并吡喃酮2。酚 O-H 基团与羰基形成分子内 H 键，我们预测这些 H 键在极性溶剂存在下可以扭曲成它们最优选的构象。区域选择性 6 -endo-dig环化似乎在热力学上优于 5 -exo-dig循环化，由 DFT 计算支持。该策略之所以引人注目，是因为它无试剂、区域选择性、原子经济性高、原子、碳和反应质量效率高。
