Comprehensive comparisons of 1H and 13C NMR chemical shift values in the furanone cores a, b, and c provide plausible support for a reassessment of the furanone nuclei of the title compounds from b to c. Totalsyntheses via enantiomerically pure lactic esters were based on the Seebach–Frater “self-reproduction of stereocenters” methodology. Attachment of the hexadienyl side-chain in a trans,trans-selective
呋喃酮核 a、b 和 c 中 1H 和 13C NMR 化学位移值的综合比较为从 b 到 c 重新评估标题化合物的呋喃酮核提供了合理的支持。通过对映异构纯乳酸酯的总合成基于 Seebach-Frater“立体中心的自我复制”方法。通过将 Seebach-Frater 烯醇化物添加到 trans-hex-4-en-1-al 而不是 trans-hex-3-en-1- 来实现以反式、反式选择性方式连接己二烯基侧链阿尔。合成材料的 c 型呋喃酮核心是通过模型 γ-羟基-β-氧代酯(化合物 50)及其含己二烯的对应物 29 的单酰化或双酰化实现的。我们的合成证实了六种化合物的新型连接性。此外,在五种情况下,他们需要修改季碳原子的构型。此外,他们允许阐明四个以前未分配的立体中心的配置。给出了为什么标题化合物的呋喃酮核心被误解为 a 和/或 b 而不是 c 的事后分析。还讨论了为什么杂环中的立体中心配置不正确,基于
