spectroscopic analysis, while the structure of 2 was proposed by analogy to 1.4 Herein, we would like to disclose a route to the chemical synthesis of 2, which may also be amenable to the synthesis of other members of this family.5 This reaction sequence constitutes the first totalsynthesis of a member of the reveromycin family and unambiguously confirms the proposedstructures for 2 and 1.
reveromycins A (1) 和 B (2) 属于一个新的天然产物家族,已从链霉菌属的土壤放线菌中分离出来。 1 这两种化合物都可能通过干扰与表皮生长相关的元素来抑制真核细胞的生长因子受体通路。2,3 1 和 2 的分子结构分别以 [6,6] 或 [5,6] 螺酮核为特征,并装饰有两个以羧酸单元结尾的高度不饱和侧链。1的相对和绝对构型是通过化学降解和光谱分析确定的,而2的结构是通过类比1.4提出的。这里,我们想公开一条化学合成2的路线,这也可能适用于合成这个家族的其他成员。
