along with their 4'-methylated derivatives are naturally occurring 2,4'-biphenols that have been isolated from the Magnoliaceae. Herein, these natural products have been synthesized from a common intermediate, which was obtained by a microwave-promoted, hetero-geneously catalyzed, and protecting-group-free Suzuki-Miyaura coupling reaction in an aqueous medium. These reaction conditions were also successfully
木兰醛 B 和 E 及其 4'-甲基化衍生物是天然存在的 2,4'-双酚,已从木兰科植物中分离出来。在此,这些天然产物是由一种常见的中间体合成的,该中间体是通过微波促进、异相催化和无保护基团的 Suzuki-Miyaura 偶联反应在水性介质中获得的。这些反应条件也成功地应用于黏菌代谢物双联苯 B 的一步合成。
