stereostructure of glabramycin B, which is an antibacterial 10-membered lactone fused with 4-oxygenated cyclohexanone, was presumed on comparison with related compounds, and concise synthesis of our proposed structure of glabramycin B was achieved via dianion alkylation, Shiina’s lactonization, and Stille cross coupling. We succeeded in the reassignment of its relative configuration.
通过与相关化合物进行比较,推测了glabramycin B(一种与4-氧合环己酮融合的抗菌性10元内酯)的立体结构,并通过双阴离子烷基化,Shiina的内酯化和Stille方法完成了我们所建议的glabramycin B结构的简明合成。交叉耦合。我们成功地重新分配了它的相对配置。
