  Ru(III)-Catalyzed Cyclization of Arene-Alkene Substrates via Intramolecular Electrophilic Hydroarylation

  摘要：

  We herein report that RuCl3/AgOTf has proven to be a hydroarylation catalyst with an efficiency and scope superior to previously known methods. This catalyst demonstrated consistent performance with arene-ene substrates of diverse structural features, providing good to excellent yields of cyclization products (chromanes, tetralins, terpenoids, dihydrocoumarins).

  Abstract Amberlyst 15 resin supported the tandem reaction of cinnamic acids with phenols under solvent-free reaction condition has been introduced to afford 4-aryl-3,4-dihydrocoumarin (neoflavanone) derivatives. The efficiency of solid acidic sulfonic resin (A-15) has been illustrated in two reaction activation methods such as microwave irradiation and conventional heating. The important roles of Amberlyst

  摘要 Amberlyst 15 树脂支持肉桂酸与酚类在无溶剂反应条件下的串联反应，得到 4-芳基-3,4-二氢香豆素（新黄烷酮）衍生物。固体酸性磺酸树脂 (A-15) 的效率已通过微波辐射和常规加热两种反应活化方法进行了说明。Amberlyst 15 的重要作用通过在微波辐射的辅助下比常规加热在更短的时间内产生高产率 4-芳基-3,4-二氢香豆素，以及其六次催化剂运行的高回收率和可重复使用性而得到强烈强调。通过XRD和FE-SEM对原始催化剂和回收催化剂进行表征，以研究再利用催化剂的表面与其可回收性的相关性。

  Coumarins are ubiquitous in plant kingdom and have been used as antitumor, antifungals, anticoagulants, insecticides. Chalcones are also widespread in plant kingdom and have been known to possess diverse biological activities; antibacterial, antifungal, antitumor and anti-inflammatory, etc. As they are considered as important natural products, numerous synthetic approaches have been reported up to the present. We devise a new selective method of preparing dihydrocoumarins and chalcones from aryl cinnamates by the selection of reagents. Dihydrocoumarin derivatives were prepared selectively by using intramolecular cyclization catalyzed by p-toluene sulfonic acid. Also, chalcones were prepared by Fries-rearrangement catalyzed by $TiCl_4$. This method can be used for preparing various coumarin & chalcone compounds.

  香豆素广泛存在于植物王国中，并已被用作抗癌剂、抗真菌剂、抗凝血剂和杀虫剂。查尔酮也在植物王国中广泛分布，并且已知具有多种生物活性，包括抗菌、抗真菌、抗癌和抗炎等。由于它们被认为是重要的天然产物，迄今为止已经报道了许多合成方法。我们设计了一种新的选择性方法，通过选择试剂，从芳基肉桂酸制备二氢香豆素和查尔酮。通过使用对甲苯磺酸催化的分子内环化反应，选择性地制备了二氢香豆素衍生物。此外，还通过三氯化钛催化的Fries重排反应制备了查尔酮。这种方法可以用于制备各种香豆素和查尔酮化合物。

  The regioselective 1,4-addition of CuSCN catalyzed Grignard reagents to the substituted coumarins are reported. The Li2MnCl4 reagent is used to transmetallate magnesium by manganese. It adds regioselectively to coumarins and forms 1,4-addition products with higher yield under the atmosphere of nitrogen gas and at a lower temperature

• TMSOTf-catalyzed intramolecular seleno-arylation of tethered alkenes: A novel method for the solid-phase synthesis of dihydrocoumarins and coumarins
  作者：E Tang、Wen Li、Zhang Yong Gao、Xi Gu

  日期：2012.6

  TMSOTf-catalyzed intramolecular seleno-arylation of tethered alkenes was performed using polystyrene-supported succinimidyl selenide as the selenium source. This catalytic process provides an efficient method for the regioselective synthesis of dihydrocoumarins possessing a seleno-functionality, followed by traceless cleavage of selenium linker to provide dihydrocoumarins and coumarins in good yields and purities.
