Abstract We present a four-step synthesis of (+)-artemone from (–)-linalool, featuring iminium organocatalysis of a doubly diastereoselective conjugate addition reaction. The strategy follows a proposed biosynthetic pathway, rapidly generates stereochemical complexity, uses no protecting groups, and minimizes redox manipulations. We present a four-step synthesis of (+)-artemone from (–)-linalool, featuring
摘要 我们提出了从(-)-芳樟醇合成(+)-青蒿酮的四步合成法,其特征在于双非对映选择性共轭加成反应的亚胺基有机催化。该策略遵循拟议的生物合成途径,快速产生立体化学复杂性,不使用保护基,并最大程度地减少氧化还原操纵。 我们提出了从(-)-芳樟醇合成(+)-青蒿酮的四步合成法,其特征在于双非对映选择性共轭加成反应的亚胺基有机催化。该策略遵循拟议的生物合成途径,快速产生立体化学复杂性,不使用保护基,并最大程度地减少氧化还原操纵。
