developed a route to stereochemically diverse variants of 2,18‐seco‐lankacidinol B and found that the stereochemical assignment at C4 requires revision. This has interesting implications for the biosynthesis of natural products of the lankacidin class, all of which possessed uniform stereochemistry prior to this finding. We have evaluated 2,18‐seco‐lankacidinol B and three stereochemical derivatives against
兰卡西丁是一组聚酮化合物天然产物,具有对抗多种革兰氏阳性菌菌株的活性。我们开发了一条获得 2,18- seco -lankacidinol B 立体化学多样化变体的路线,并发现 C4 的立体化学分配需要修改。这对于兰卡西丁类天然产物的生物合成具有有趣的意义,在这一发现之前,所有这些天然产物都具有统一的立体化学。我们评估了 2,18- seco -lankacidinol B 和三种立体化学衍生物对一组致病性革兰氏阳性和革兰氏阴性细菌的作用。
