In contrast to the simple 4,4′-bi-1,3-dioxanyl derivative 6, which has no conformational preference at the inter-ring bond, the derivatives 9 and 10, which have two strategically placed axial methyl groups, show conformational preferences exceeding 95 %. This is related to the conformational preference found in one of the substructures of the natural product prymnesin. (© Wiley-VCH Verlag GmbH & Co
与在环间键处没有构象偏好的简单 4,4'-bi-1,3-二氧六环衍生物 6 相比,具有两个战略性放置的轴向甲基的衍生物 9 和 10 显示出构象偏好超过 95%。这与在天然产物普里姆内肽的亚结构之一中发现的构象偏好有关。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
