• Montmorillonite K-10 Clay as an Efficient Solid Catalyst for Chemoselective Protection of Carbonyl Compounds as Oxathiolanes with 2-Mercaptoethanol
  作者：Nabin C. Barua、Siddhartha Gogoi、Jagat C. Borah

  DOI：10.1055/s-2004-829054

  日期：——

  Montmorillonite K-10 clay has been found to be a mild and efficient solid catalyst for the protection of a variety of carbonyl compounds, such as oxathiolanes, with 2-mercaptoethanol in good to excellent yields. In addition, by using this catalyst, high chemoselective protection of aldehydes in presence of ketones has been achieved.

  蒙脱石 K-10 粘土已被发现是一种温和而有效的固体催化剂，用于保护各种羰基化合物，如氧硫杂环戊烷，与 2-巯基乙醇以良好到极好的收率。此外，通过使用这种催化剂，在酮的存在下实现了对醛的高化学选择性保护。
