The synthesis of enantiopure thiols is of significant interest for industrial and academic applications. However, direct asymmetric approaches to free thiols have previously been unknown. Here we describe a novel organocascade that is catalyzed by a confined chiral phosphoric acid and furnishes O-protected β-hydroxythiols with excellent enantioselectivities. The method relies on an asymmetric thiocarboxylysis
对映纯硫醇的合成对工业和学术应用具有重要意义。然而,以前不知道游离硫醇的直接不对称方法。在这里,我们描述了一种新型有机级联,它由受限的手性磷酸催化并提供具有优异对映选择性的 O 保护的 β-羟基硫醇。该方法依赖于内消旋环氧化物的不对称硫代羧化,然后是分子内酯交换反应。通过改变反应条件,还可以化学选择性和对映选择性地获得中间体硫酯。
