    独特的β-Turn类肽结构及其作为不对称催化剂的应用。
    摘要:
    类肽,N-取代的甘氨酸低聚物,代表了一类重要的拟肽,可以在溶液中折叠成三维结构。然而,大多数折叠的类肽结构类似于螺旋,这可能限制了它们的应用,特别是在不对称催化中。在这项工作中,首次描述了吡咯烷类β-turn类肽的独特实例,并在固态,单晶X射线分析和溶液中通过圆二色光谱进行了表征。此外,还证明了它们通过在水中的不对称迈克尔反应产生γ-硝基醛的高效和对映选择性催化活性。新的β-turn-like类肽的结构性质和DFT-D3计算,

    A series of simple 4‐hydroxyprolinamides was synthesised and they were found to act as organocatalysts for the asymmetric conjugate addition of aldehydes to nitroolefins in excellent yields (98%), with complete diastereoselectivity (99:1, syn:anti) and enantioselectivity (98% ee for syn). Furthermore, the use of low catalyst loadings (5 mol%) and a low aldehyde molar excess (1.5 equivalents) were achieved
