An efficient de novo synthesis of vineomycinone B2 methyl ester has been achieved. The longest linear route required only 14 steps from achiral commercially available starting materials (4.0% overall yield). The key transformations included the de novo asymmetric synthesis of two key fragments, which were joined by a convergent late stage Suzuki's glycosylation for the construction of the aryl beta-C-glycoside
已经实现了葡萄霉素 B2 甲酯的有效从头合成。最长的线性路线仅需要从非手性市售起始材料(总产率为 4.0%)的 14 个步骤。关键转化包括两个关键片段的从头不对称合成,这些片段通过收敛的后期 Suzuki 糖基化加入,用于构建芳基 β-C-糖苷。随后的 BBr3 一锅脱苄基、去甲基化和空气氧化提供了葡萄霉素 B2 甲酯。
