A novel class of fused thiochroman derivatives has been prepared by an efficient and versatile synthetic procedure involving nucleophilic displacement of the side-chain iodo substituent in 2-deoxy-2-C-iodomethyl glucosides by thiophenolate ions, and subsequent intramolecular C-glycoside formation. A range of aromatic substituents is tolerated, and the subsequent facile selective oxidation of the sulfur
已经通过一种有效且通用的合成方法制备了新型的稠合的硫代苯并二氢吡喃衍生物,该方法涉及通过硫代酚酸根离子亲核取代2-脱氧-2- C-碘甲基葡糖苷中侧链碘取代基,并随后形成分子内C-糖苷。容许一定范围的芳族取代基,并且随后容易地将硫选择性氧化为亚砜或砜水平,从而扩大了一系列化合物的范围和分子多样性。发现在芳族部分上带有亲脂性取代基的亚砜和砜衍生物的选择在低微摩尔范围内具有抗疟活性。
