(−)-conduritol F starting from readily available d-sorbitol is described. The route involves as a key step an efficient one-pot sequence consisting of the Swern oxidation of a 1,6-diol followed by a highly stereoselective intramolecular pinacol coupling of the resultant dialdehyde, promoted by samarium diiodide.
描述了从容易获得的d-山梨糖醇开始的和(-)-conduritol F的合成。该路线涉及一个关键的有效步骤,该步骤由1,6-二醇的Swern氧化,随后由二碘化sa促进的高度立体选择性的分子内频哪醇偶联生成二醛组成。
