  Base initiated aromatization/C O bond formation: a new entry to O-pyrazole polyfluoroarylated ethers

  摘要：

  A base initiated intermolecular SNAr reaction of pyrazolones with polyfluoroarenes was developed. The process involved the isomerization aromatization of pyrazolone followed by the C-O bond formation via the selective C-F bond cleavage. With this strategy, a wide range of O-pyrazole polyfluoroarylated ethers bearing diverse functional groups were synthesized in mild to good yields. Additionally, our method was also applied to the isoxazol substrates. (C) 2014 Elsevier Ltd. All rights reserved.

  A facile one-pot sequential conjugate addition/dearomative fluorination transformation of isoxazol-5(4H)-ones with nitroolefins and N-fluorobenzenesulfonimide (NFSI) has been developed. By using a bifunctional chiral tertiary amino-thiourea catalyst, a series of chiral fluorinated isoxazol-5(4H)-ones containing one fluorine-substituted quarternary stereocenter were obtained in high yields with high

  已经开发了一种方便的一锅连续的异恶唑-5（4 H）-酮与硝基烯烃和N-氟苯磺酰亚胺（NFSI）的顺序共轭加成/脱氟化法转化的方法。通过使用双功能手性叔氨基-硫脲催化剂，可以高收率获得具有高对映异构和非对映异构选择性的一系列含有一个氟取代的叔叔立体中心的手性氟化异恶唑-5（4 H）-。加合物的进一步转化可以得到具有三个连续立体中心的异恶唑烷-5-一衍生物。

  the present study, we successfully developed an efficient thiocyanation of carbonyl compounds by using low-toxicity and inexpensive ammonium thiocyanate as the thiocyanate source under visible light in air (O2) at room temperature. This unified strategy is very facile for thiocyanation of various carbonyl compound derivatives (β-keto esters, β-keto amides, pyrazo-5-ones, isoxazol-5-ones, etc.). More

  在本研究中，我们利用低毒且廉价的硫氰酸铵作为硫氰酸盐源，在室温下、空气（O 2 ）中可见光下成功开发了羰基化合物的高效硫氰化反应。这种统一的策略非常适合各种羰基化合物衍生物（β-酮酯、β-酮酰胺、吡唑-5-酮、异恶唑-5-酮等）的硫氰化。更重要的是，反应顺利进行，无需添加光催化剂和强氧化剂，最终最大限度地减少了化学废物的产生。此外，这种绿色和可持续的合成化学可用于生物相关化合物的后期功能化（LSF），这为在温和的反应条件下实现药物的顺利和清洁的硫氰化提供了独特的机会。
