The first biomimetic total syntheses of three biologically meaningful acylphloroglucinols, watsonianones A and B and corymbone B, with potent antiplasmodial activity, were performed. Their total syntheses were carried out through a diversity-oriented synthetic strategy from congener 2,2,4,4-tetramethyl-6-(3-methylbutylidene)cyclohexane-1,3,5-trione with high step efficiency. The spontaneous enolization/air
进行了具有生物活性的三种具有生物学意义的酰基间苯三酚,屈臣氏酮A和B和co酮B的首次仿生全合成。它们的总合成是通过同源的2,2,4,4-四甲基-6-(3-甲基丁烯)环己烷-1,3,5-三酮通过面向多样性的合成策略进行的,具有较高的步长效率。前体2,2,4,4-四甲基-6-(3-甲基丁烯)环己烷-1,3,5-三酮通过单链O2诱导的Diels-Alder反应途径自发烯醇化/空气氧化来组装键还讨论了生物合成的过氧化物中间体。
