The concise syntheses of two alkylated hydroquinone natural products, violaceoids A and C, were accomplished by a protecting-group-free method employing the commercially available 2,5-dihydroxybenzaldehyde as the starting material. The key strategy of the syntheses is the utilization of alkenylboronic acid as both the coupling and temporary protective reagents to efficiently introduce the requisite
两种烷基化对苯二酚天然产物(类紫胶类化合物A和C)的简明合成是采用无保护基团的方法,使用市售的2,5-二羟基苯甲醛作为起始原料完成的。合成的关键策略是利用烯基硼酸作为偶联剂和临时保护剂,以有效地引入类紫胶A的必需烯基侧链。此外,此处首次报道了类紫胶C的合成。
