• Eco-friendly and Highly Chemoselective 1,3-Oxathio- and 1,3-Dithioacetalization of Aldehydes Using Ionic Liquids

  DOI：10.1246/cl.2003.672

  日期：2003.8

  Room temperature ionic liquids have been employed for the first time as novel and recyclable reaction media for the chemoselective conversion of aldehydes into their corresponding 1,3-oxathio- and dithioacetal derivatives in excellent yields under mild and neutral conditions. A wide range of functional and protecting groups such as TBDMS, PMB, THP, MOM, benzyl, propargyl ethers, acetonides, carbamates and esters are survived under these reaction conditions. The recovered activated ionic liquids can be recycled for four to five subsequent runs with consistency in activity.

  室温离子液体首次被用作新型且可回收的反应介质，用于在温和中性条件下将醛选择性转化为相应的1,3-氧硫杂环和二硫杂环衍生物，产率极佳。在这些反应条件下，包括TBDMS、PMB、THP、MOM、苄基、炔丙基醚、乙缩醛、氨基甲酸酯和酯等多种功能性和保护性官能团都能稳定存在。回收的活性离子液体可循环用于后续四到五次反应，活性保持一致。

  The ionic liquid based on the 1-n-butyl-3-methylimidazolium cation has been prepared and used as an efficient catalytic medum for the chemoselective thioacetalization of carbonyl compounds. Furthermore, recycling and reuse of this ionic liquid medium has been demonstrated. Moreover, the use of this catalytic medium not only avoids the generation of waste but also provides a green process with minimal

• Chemoselective thioacetalization and transthioacetalization of carbonyl compounds catalyzed by immobilized scandium(III) triflate in ionic liquids
  作者：Ahmed Kamal、Gagan Chouhan

  DOI：10.1016/s0040-4039(03)00580-x

  日期：2003.4

  Immobilized scandium triflate [Sc(OTf)(3)] in ionic liquids has been found to be an extremely efficient and recyclable catalyst for the thioacetalization and transthioacetalization of both aromatic and aliphatic aldehydes. Significant rate acceleration and chemoselectivity was achieved by employing this catalytic system. (C) 2003 Elsevier Science Ltd. All rights reserved.
