Isonitrile-functionalized biaryl ethers can serve as key building blocks for the highly efficient one-step production of natural product inspired-macrocycles, with six or even twelve new bonds and rings with up to 50 members being formed in total yields of up to 51 %. Aliphatic diamine and diacid tethers give access to two different classes of N-substituted biaryl ether cyclopeptides, suitable for
异腈官能化联芳醚可作为高效一步生产天然产物启发的大环的关键构建块,以高达 51 % 的总产率形成六个甚至十二个新键和环,最多 50 个成员. 脂肪族二胺和二酸系链提供了两种不同类别的 N 取代联芳醚环肽,适用于文库构建。作为 MiBs(多个多组分大环化/大环,包括双功能构件)的概念性工作的一部分,研究了柔性系链的长度和类型对环化倾向的影响。(© Wiley-VCH Verlag GmbH & Co. KGaA,69451德国魏因海姆,2007)
