    An efficient, organocatalytic enantioselective addition of cyclic diketones with β,γ-unsaturated α-keto esters has been developed that affords products in high yields (up to 95 %) and excellent enantioselectivity (up to >99 % ee) under mild conditions with a low catalyst loading (2.5 mol-%). The unsaturated α-keto esters are effectively coordinated and activated through hydrogen bonds with the squaramides
    已开发出环状二酮与 β,γ-不饱和 α-酮酯的高效有机催化对映选择性加成,可在温和条件下以高产率(高达 95%)和优异的对映选择性(高达 >99%ee)提供产品低催化剂负载(2.5 mol-%)。不饱和α-酮酯通过与方酸酰胺的氢键有效配位和活化,并被证明是这种不对称有机催化反应中优异的氢键受体。该反应为获得手性迈克尔加合物提供了宝贵且容易的途径,这是生物和药物分子骨架中的重要部分。

    A direct asymmetric Michael addition of cyclic 1,3-dicarbonyl compounds to β,γ-unsaturated α-ketoesters could be efficiently catalyzed by an N,N′-dioxide–nickel(II) complex. A series of chiral warfarin derivatives were obtained in excellent yields (up to 99%) with high enantioselectivities (up to 90% ee) under mild conditions within shorter reaction time.
    N,N'-二氧化物-镍(II)络合物可以有效地催化将环状1,3-二羰基化合物直接不对称迈克尔加成到β,γ-不饱和α-酮酸酯上。在温和的条件下,在较短的反应时间内,以优异的收率(最高99%)和高对映选择性(最高90%ee)获得了一系列手性华法林衍生物。
  • Bifunctional Amine-Squaramides as Organocatalysts in Michael/Hemiketalization Reactions of β,γ-Unsaturated α-Ketoesters and α,β-Unsaturated Ketones with 4-Hydroxycoumarins

    Michael/hemiketalization reactions of 4-hydroxycoumarines with two types of enones. Tertiary amine-squaramide organocatalysts afforded the best results regarding both activity and enantioselectivity when β,γ-unsaturated α-ketoesters were used as the Michael acceptors (yields up to 98%, enantioselectivities up to 90% ee). On the other hand, the primary amine-squaramides are the best choice for related reactions of 4-hydroxycoumarins
