Stereoselective preparation of a structurally simplified 3,4-unsubstituted zaragozic acid derivative was achieved starting from D-glucose. The present approach involved the stereoselective addition of a vinyl Grignard reagent, selective cleavage of 1,2-diol, and regioselective acylation of the hydroxyl group at C-6.
从D-葡萄糖开始,立体选择性地制备了结构简化的3,4-未取代的扎拉果酸衍生物。本方法涉及乙烯基格氏试剂的立体选择性添加,1,2-二醇的选择性裂解以及C-6处羟基的区域选择性酰化。
