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。
