A concise and effective ruthenium-catalyzed asymmetric transfer hydrogenation of β-substituted α-oxobutyrolactones has been developed, delivering a series of cis-β-substituted α-hydroxybutyrolactone derivatives with excellent yields, enantioselectivities, and diastereoselectivities. Two consecutive stereogenic centers were constructed in one step through dynamic kinetic resolution under basic conditions
已经开发了一种简洁有效的钌催化 β-取代 α-氧代丁内酯的不对称转移氢化,提供了一系列具有优异产率、对映选择性和非对映选择性的顺式-β-取代 α-羟基丁内酯衍生物。通过在基本条件下的动态动力学解析,一步构建了两个连续的立体中心。该反应可以以克规模进行而不会损失活性和对映选择性。还原产物可以很容易地转化为有用的积木。
