A powerful catalyst: Quaternary stereogenic centers adjacent to tertiary stereocenters were formed with high diastereoselectivities and enantioselectivities in conjugate addition reactions between aldehydes and β,β‐disubstituted nitroolefins by using a peptidic catalyst (see scheme). γ‐Amino acids and heterocyclic compounds bearing quaternary stereogenic centers are easily accessible from the products
强大的催化剂:在醛与β,β-二取代的硝基烯烃之间通过肽类催化剂进行共轭加成反应时,与叔立体中心相邻的四级立体中心具有很高的非对映选择性和对映选择性(请参见方案)。容易从产品中获得带有季立体中心的γ-氨基酸和杂环化合物。
