ABSTRACT Vialinin B is a natural 3-phenyldibenzo[b,d]furan product with a powerful inhibitory activity against tumor necrosis factor (TNF)–α production. This article describes the synthesis of three types of biotinylated p-terphenyls designed for clarifying the target molecule of vialinin B. Construction of the carbon backbone of the core was accomplished by stepwise Suzuki–Miyaura coupling while the
摘要 Vialinin B 是一种天然的 3-苯基二苯并[b,d]呋喃产物,对肿瘤坏死因子 (TNF)-α 的产生具有强大的抑制活性。本文描述了三种类型的生物素化对三联苯的合成,旨在阐明小鸟苷 B 的目标分子。核心碳骨架的构建通过逐步 Suzuki-Miyaura 偶联完成,而苯基二苯并呋喃部分则由 Ullmann 构建反应。生物素单元通过点击化学连接。图形概要
