Putaminoxin E, a natural nonanolide, and its C-9 epimer were synthesized for the first time starting from pentane-1,5-diol and butyraldehyde. The synthetic sequences involve Maruoka asymmetric allylation, Sharpless kinetic resolution, and ring-closing metathesis as the key steps. The cytotoxic and antimicrobial activities of these compounds were evaluated.
首次以戊烷-1,5-二醇和丁醛为原料合成了一种天然壬烯醇胺类化合物 Putaminoxin E 及其 C-9 差向异构体。合成序列涉及 Maruoka 不对称烯丙基化、Sharpless 动力学拆分和闭环复分解作为关键步骤。评估了这些化合物的细胞毒性和抗微生物活性。
