A catalytic protocol for the enantio- and diastereoselective reduction of α-substituted-β-keto carbonitriles is described. The reaction involves a DKR-ATH process with the simultaneous construction of β-hydroxy carbonitrile scaffolds with two contiguous stereogenic centers. A wide range of α-substituted-β-keto carbonitriles were obtained in high yields (94%–98%) and excellent enantio- and diastereoselectivities
描述了用于α-取代的-β-酮腈的对映体和非对映体选择性还原的催化方案。该反应涉及DKR-ATH方法,该方法同时构建具有两个连续的立体异构中心的β-羟基甲腈支架。以高产率(94%–98%)和出色的对映和非对映选择性(高达> 99%ee,高达> 99:1 dr)获得了多种α-取代-β-酮腈。非对映选择性的起源也通过DFT计算得到了合理化。此外,这种方法可以快速获得异戊ox酮和
