Total syntheses of serofendic acids A (1a) and B (1b) are described. The key strategic element of the approach involves the novel tin-free homoallyl-homoallyl radical rearrangement of 5 for the construction of bicyclo[2.2.2]octane ring system 4. In addition, the conversion of methyl atisirenoate 2 to serofendic acids A (1a) and B (1b) was achieved on the basis of the Michael reaction of sodium thiomethoxide
描述了全血脂酸A(1a)和B(1b)的合成。该方法的关键战略要素涉及用于构建双环[2.2.2]辛烷环系4的新颖的无锡均烯丙基-均烯丙基自由基重排5。此外,阿西瑞壬酸甲酯2转化为血凝烯酸A(1a )和B(1b)是在硫代甲醇钠的迈克尔反应的基础上获得的。
