  Synthesis and Evaluation of Estrogen Agonism of Diaryl 4,5-Dihydroisoxazoles, 3-Hydroxyketones, 3-Methoxyketones, and 1,3-Diketones: A Compound Set Forming a 4D Molecular Library

  摘要：

  In this paper, the preparation and systematic evaluation of estrogen receptor alpha (ER alpha) and estrogen receptor beta (ER beta) activities of some diaryl-1,3-diones and their synthetic intermediates, diaryl-4,5-dihydroisoxazoles, diaryl-3-hydroxyketones, diaryl-3-methoxyketones, and diaryl-2-(dimethyl-lambda(4)-sulfanylidene)-1,3-diones, is described. The set of 72 compounds constitutes a general schematic structure aryl1-linker1-spacer-linker2-aryl2, where the linker1-spacer-linker2 length varies between 4 and 8 carbons. The set of compounds was applied here to map and explore the active sites of subtypes ER alpha and ER beta. The highest activities were obtained with dihydroisoxazole and hydroxyketone spacers, but even the most flexible diones with unsubstituted aryl groups showed some agonism. Most compounds were found to be ER alpha selective or to activate both receptors, but in some cases we saw also clearly stronger ER beta activation.

• One-Pot Synthesis of Isoxazolines from Aldehydes Catalyzed by Iodobenzene
  作者：Jie Yan、Liuquan Han、Bijun Zhang、Changbin Xiang

  DOI：10.1055/s-0033-1340464

  finally, a 1,3-dipolar cycloaddition between the nitrile oxides and alkenes occurs to provide the isoxazolines in moderate to good yields. A convenient one-pot, three-step procedure for the synthesis of isoxazolines starting from aldehydes has been developed involving catalytic cycloaddition between nitrile oxides and alkenes, in which iodobenzene is used as the catalyst for the in situ generation of a hypervalent

  摘要 已经开发了一种方便的一锅三步法，从醛类开始合成异恶唑啉，涉及在腈氧化物和烯烃之间进行催化环加成反应，其中碘代苯用作原位生成高价碘中间体的催化剂。在这种方法中，醛首先被硫酸羟胺转化为醛肟，然后被原位生成的高价碘中间体氧化为腈。最后，在腈和烯烃之间发生1，3-偶极环加成反应，以中等至良好的产率提供异恶唑啉。 已经开发了一种方便的一锅三步法，从醛类开始合成异恶唑啉，涉及在腈氧化物和烯烃之间进行催化环加成反应，其中碘代苯用作原位生成高价碘中间体的催化剂。在这种方法中，醛首先被硫酸羟胺转化为醛肟，然后被原位生成的高价碘中间体氧化为腈。最后，在腈和烯烃之间发生1，3-偶极环加成反应，以中等至良好的产率提供异恶唑啉。

  An effective and environmentally benign procedure for the synthesis of isoxazolines and isoxazoles has been developed by a cycloaddition of nitrile oxides with alkenes or alkynes in water. In this approach, potassium chloride is first oxidized into chlorine in water by the environmentally friendly oxidant Oxone®, then aldoximes are oxidized into nitrile oxides by the in situ generated hypochlorous

• Synthesis of Hydroximoyl Chlorides from Aldoximes and Benzyltrimethylammonium Tetrachloroiodate (BTMA ICl4)
  作者：Shuji Kanemasa、Haruhiko Matsuda、Akio Kamimura、Takaaki Kakinami

  DOI：10.1016/s0040-4020(99)01047-9

  日期：2000.2

  Benzyltrimethylammonium tetrachloroiodate (BTMA ICl4) acts as a convenient reagent to convert aldoximes to hydroximoyl chlorides by a simple procedure. When an aldoxime is treated with BTMA ICl4 in dichloromethane, the suspension of BTMA ICl4 shortly diasappears as the reaction proceeds. The resulting BTMA ICl2 can he precipitated out by adding diethyl ether. Not only stable aromatic and heteroaromatic hydroximoyl chlorides can be isolated by this method but also rather unstable aliphatic hydroximoyl chlorides can be generated in situ. 1,3-Dipole trapping with a dipolarophile is performed in one flask and in some cases the chlorination is successfully performed in the presence of dipolarophile and triethylamine. Effect of MS 4A has been examined. (C) 2000 Elsevier Science Ltd. All rights reserved.
