Abstract A short total synthesis of a diacetoxylated E,E-diene lactone ent-hyptenolide, was achieved involving from Phosphonate and cis-butene 1,4-diol. Brown Asymmetric allylation, Acrylation, Acetylation, Ring-closing metathesis as the key steps has been described. Moreover, the biological activity of ent-hyptenolide was evaluated on HeLa, A549, IMR32, and MDA-MB231 cancer cell lines. The ent-hyptenolide
摘要 通过膦酸酯和顺丁烯 1,4-二醇实现了双乙酰氧基化 E,E-二烯内酯 ent-hyptenolide 的短程全合成。Brown 描述了作为关键步骤的不对称烯丙基化、丙烯酸化、乙酰化、闭环复分解。此外,在 HeLa、A549、IMR32 和 MDA-MB231 癌细胞系上评估了 ent-hyptenolide 的生物活性。ent-hyptenolide 选择性和有效地抑制 IMR32 细胞系的生长。图形概要
