for the highly enantioselective desymmetrization of 2-alkyl-substituted 1,3-diols is presented. A combination of computational and experimental studies has been utilized to understand the origin of the stere-ocontrol of oxidative desymmetrization of 1,3-diol benzylideneacetals. DFT calculations demonstrate that the acetal protecting group is highly influential for high enantioselectivity, and a simple
介绍了 2-烷基取代的 1,3-二醇的高度对映选择性去对称化的一般方法。已利用计算和实验研究的组合来了解 1,3-二醇亚苄基缩醛氧化去对称化立体控制的起源。DFT 计算表明缩醛保护基团对高对映选择性有很大影响,并且已经设计了一种简单但有效的新保护基团。去对称化反应以对多种底物的高对映选择性进行。此外,反应条件也显示出对 2,2-二烷基取代的 1,3-二醇的去对称化有效,这提供了带有无环全碳四元立体中心的手性产物。该方法已应用于二氢吲哚生物碱的正式合成。
