polydeoxypropionates in optically pure form has been developed. Taking advantage of our previously established strategy for the asymmetric and stereodivergent synthesis of trideoxypropionate building blocks, we have now been able to assemble large polydeoxypropionate chains with defined configuration in a highly convergent manner. Central steps of this approach include two Suzuki–Miyaura cross‐coupling reactions with
已经开发了高度立体可控的和灵活的光学纯形式的生物相关聚脱氧丙酸酯的途径。利用我们先前建立的不对称和立体发散的三脱氧丙酸酯结构单元合成策略,我们现在能够以高度收敛的方式组装具有确定构型的大型聚脱氧丙酸酯链。该方法的主要步骤包括两个Suzuki-Miyaura交叉偶联反应,以及随后的非对映选择性加氢反应,以优异的收率和完全的立体化学控制作用,将三个高级合成中间体连接在一起。我们已成功地将此策略应用于糖脂膜成分phthioceranic acid和hydroxyphthioceranic acid的不对称合成,
