• Synthesis of isochromans via Fe(OTf)2-catalyzed Oxa-Pictet–Spengler cyclization
  作者：Jimei Zhou、Chao Wang、Dong Xue、Weijun Tang、Jianliang Xiao、Chaoqun Li

  Fe(OTf)2 has been found to be an efficient catalyst for the Oxa-Pictet–Spengler cyclization reaction leading to isochromans. A series of substituted isochromans were obtained with good to excellent isolated yields by coupling β-arylethanols with aldehydes or ketals under the catalysis of 1 mol% of Fe(OTf)2 at 70 °C. Using a cheap, less-toxic catalyst with water as the only byproduct, this iron-catalyzed

  已发现Fe（OTf）2是导致异色团的Oxa-Pictet-Spengler环化反应的有效催化剂。通过 在70℃下1摩尔％的Fe（OTf）2催化下，将β-芳基乙醇与醛或缩酮偶联，可以得到一系列具有良好分离效果的取代异色满。使用廉价的，毒性较小的催化剂，水是唯一的副产物，这种铁催化的Oxa-Pictet-Spengler反应可以被认为对环境友好且经济实惠。

• Bismuth Triflate as a Safe and Readily Handled Source of Triflic Acid: Application to the Oxa–Pictet–Spengler Reaction
  作者：Benaissa Bouguerne、Pascal Hoffmann、Christian Lherbet

  DOI：10.1080/00397910903026715

  日期：2010.2.26

  The oxa-Pictet-Spengler reaction with various aldehydes and -arylethanol yields 1-substituted-isochromans in the presence of bismuth triflate as catalyst in good yields. The method was extended to O,O-acetals to afford the corresponding 1,1-disubstituted-isochromans in good yields. These studies also provide insights into the catalytic role of triflic acid generated upon hydrolysis of Bi(OTf)3 by residual water. The low toxicity and easy handling of Bi(OTf)3 by comparison with triflic acid make these procedures an attractive method to provide isochromans in good to excellent yields.
• Silica-supported policresulen as a solid acid catalyst for organic reactions
  作者：Kexing Zeng、Zhipeng Huang、Jie Yang、Yanlong Gu

  DOI：10.1016/s1872-2067(15)60910-x

  日期：2015.9

  A new type of solid catalyst was prepared by coating a thin layer of policresulen, an inexpensive polymer prepared via condensation of 2-hydroxy-4-methylbenzenesulfonic acid and formaldehyde that has been used as commercially available drug, onto the surface of silica. The policresulen component is insoluble in many organic solvents and can be adsorbed on silica with the aid of hydrogen bonding. The obtained silica/policresulen composite showed remarkable catalytic activity for various organic reactions. In model reactions, the catalyst can be recycled several times without significant loss of activity. The salient features of using this acid catalyst in organic reactions include cost-effectiveness, simple and time-efficient preparation, and the convenience of controlling the acid loading on the solid.

• Design and development of 2,3-benzodiazepine (CFM) noncompetitive AMPA receptor antagonists
  作者：Rosaria Gitto、Maria Zappalà、Giovambattista De Sarro、Alba Chimirri

  2,3-Benzodiazepines represent a class of heterocyclic compounds that interact with AMPA-type glutamate receptors in a noncompetitive manner. These compounds have attracted great interest for their pharmacological effects against acute and chronic neurodegenerative diseases, such as ischemia and epilepsy. We synthesized a large number of 2,3-benzodiazepine derivatives, which showed anticonvulsant properties in different seizure models and a noncompetitive blockade of AMPA receptor. This article will briefly mention our work in this field and the main SAR considerations. (C) 2002 Editions scientifiques et medicales Elsevier SAS. All rights reserved.
