Stereoselective intramolecular oxymercuration has been demonstrated as the key reaction for the efficient preparation of mono- and dihydroxylated unsymmetrical bis-tetrahydrofuran skeletons present in naturally occurring biologically active acetogenins using carbohydrates. These trans- and syn-selective intramolecular oxymercurations were explored in an enantioselective synthesis of the bis-tetrahydrofuran
已经证明,立体选择性分子内氧合是使用碳水化合物有效制备存在于天然存在的生物活性产乙酸素中的单和二羟基化的不对称双四氢呋喃骨架的关键反应。在对粘蛋白的双-四氢呋喃骨架的对映选择性合成中探索了这些反式和顺式选择性分子内氧化汞。
