β-unsaturated ketone intermediates and aza-Michael addition were not involved in this coupling reaction which made it unique when compared to otherreactions reported in literature. Inexpensive iodine catalyst, easy accessible raw materials, mild reactionconditions, good functional group tolerance and excellent selectivity made this coupling reaction be a practical method. This reaction can also be
已经开发出碘催化的β-羟基酮与芳香胺的偶联反应,以产生β-氨基酮和苯并[ h ]喹诺酮。贵金属催化剂,氧化剂,α,β-不饱和酮中间体和氮杂-迈克尔加成均不参与该偶联反应,因此与文献报道的其他反应相比,它具有独特性。廉价的碘催化剂,易于获得的原料,温和的反应条件,良好的官能团耐受性和出色的选择性使这种偶联反应成为一种实用的方法。该反应也可以扩大规模。
Zirconium Tetrakis(dodecylsulfate) as an Efficient and Recyclable Lewis Acid-Surfactant-Combined Catalyzed C-C and C-N Bond Forming Under Mild and Environmentally Benign Conditions
A green catalytic method for C-C and C-N bond forming via Michaeladdition of aromatic amines and indoles to electron-deficientolefins using Zirconium tetrakis(dodecylsulfate) in water under mild conditions with high yields and selectivity has been developed. The reusability of the catalyst has been successfully examined without any noticeable loss of its catalytic activity.
A novel Pd-catalyzed intermolecular cascade oxidative amination of homoallylic alcohols to yield β-amino ketones has been developed by using TBHP as the terminal oxidant. The synthetic utility of the reaction can be performed by installing the carbonyl and amino groups along an alkyl chain in one step, offering several advantages such as simple starting materials and easy operation. The resultant β-amino
