A simple and convenient one-pot protocol for the chemoselective C2-homologation of carbohydrate-derived glycols is described. The method comprises the chemoselective oxidation of the glycol to the corresponding hydroxyaldehyde and the subsequent Wittig alkenylation. In addition, the method does not need selective protective group manipulation, and it is safe, economical, fast (5 to 6 h), and bench-friendly
描述了一种简单且方便的一锅操作规程,用于碳水化合物衍生的二醇的化学选择性C 2-同源。该方法包括将二醇化学选择性氧化成相应的羟基醛和随后的Wittig烯基化。此外,该方法不需要选择性的保护基操作,并且安全,经济,快速(5至6小时)且易于使用。讨论了其一般用途。
