The stereoselective total synthesis of siladenoserinols A and D has been accomplished using carbohydrate as a chiral template. The feature of this work is to build the medicinally privileged 6,8-DOBCO scaffold through a cascade reaction of hydrogenation/deacetalization/ketalization in a one-pot process, that is, to take advantage of a thermodynamically controlled bicyclization of polyhydroxyketone
使用碳水化合物作为手性模板已经完成了硅腺芥子醇A和D的立体选择性全合成。这项工作的特点是通过一锅法中加氢/脱缩醛/缩酮化的级联反应来构建具有医学优势的6,8-DOBCO支架,即利用HCl / MeOH反应条件。当前的具有成本效益的合成策略可以促进硅腺苷丝氨酸的生物活性研究。
