Fine chemicals from HMF: A new short, efficient and malleable synthetic route for the production of bis(5-aryl-2-yl) methane scaffolds (present in coffee volatiles and licorice, and with multiple applications in polymer synthesis and cross-linking) is reported. This route avoids the use of protecting groups and utilizes readily available synthetic intermediates. A wide scope of the decarboxylative
来自 HMF 的精细化学品:一种用于生产双 (5-芳基-2-基) 甲烷支架(存在于咖啡挥发物和甘草中,并在聚合物合成和交联中具有多种应用)的新型短、高效和可延展的合成路线被报道。该路线避免使用保护基团并利用容易获得的合成中间体。讨论了 HMF 衍生的糠酸的广泛的脱羧交叉偶联,并显示了酸催化自缩合的详细优化,对于广泛的取代基具有良好的产率。
