The total synthesis of (−)-actinobolin 3, an antipode of the natural product, starting from d-glucose is described. A three-component coupling reaction of functionalized cyclohexenone (+)-6 derived from d-glucose by way of Ferrier's carbocyclization reaction, with vinyl cuprate and 2-alkoxypropanal 7 effectively constructed the carbon framework of 3 in a highly stereoselective manner. In an aldol process
描述了从d-葡萄糖开始的天然产物的对映体(-)-actinobolin 3的总合成。通过Ferrier的碳环化反应,由d-葡萄糖衍生的官能化环己烯酮(+)- 6的三组分偶联反应与铜酸乙烯酯和2-烷氧基丙醛7有效地以高度立体选择性的方式构建了3的碳骨架。在三组分偶联反应的羟醛过程中,通过选择2-羟基丙醛中羟基官能团的保护基团和反应溶剂,实现了立体化学控制(螯合和Felkin–Anh条件)。天然对映体(+)-肌动蛋白1的形式合成从d-葡萄糖开始,也完成了。
