• Regioselective acetylation of carbohydrates and diols catalyzed by tetramethyl-ammonium hydroxide in water

  日期：——

  A novel method for an efficient regioselective acetylation of carbohydrates and diols in aqueous solution is described. Treatment of substrates with 1-acetylimidazole, and tetramethyl-ammonium hydroxide (TMAH) in water under mild conditions gave highly regioselective acetylation for primary hydroxyl groups. This discovery provides an eco-friendly way for selective acetylation of non-protected glycosides

  描述了一种用于在水溶液中有效地对碳水化合物和二醇进行区域选择性乙酰化的新方法。在温和的条件下，在水中用1-乙酰基咪唑和氢氧化四甲基铵（TMAH）处理底物，可得到伯羟基的高度区域选择性乙酰化。该发现为水中非保护的糖苷和二醇的选择性乙酰化提供了一种环保的方法，避免了使用有毒有机溶剂和避免对仲羟基进行预保护的必要性。
