A new methodology named solid-phase reactive chromatography (SPRC), which combines reaction, separation, and purification into a single unit for the preparation of small samples, is described. This method was illustrated in the synthesis of some natural bioactive compounds, namely, methoxylated analogues of resveratrol, alkylresorcinols, and 5-aryl-2,4-pentadienoates, over a column of alumina-KF under
描述了一种名为固相反应色谱 (SPRC) 的新方法,它将反应、分离和纯化结合到一个单元中,用于制备小样品。这种方法在一些天然生物活性化合物的合成中得到了说明,即白藜芦醇、烷基间苯二酚和 5-芳基-2,4-戊二烯酸酯的甲氧基化类似物,在微波辐射下,使用 Wittig 和 Horner-在氧化铝-KF 柱上合成。埃蒙斯反应。这种方法允许在较短的反应时间内制备具有高纯度和良好至极好产率的目标烯烃。
