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。
Michael addition of aromatic amines to enones but there is no report of using α‐amylase enzyme to catalyze this transformation. The α‐amylase from Aspergillus oryzae was found to catalyze the Michael addition of various aryl (hetero) amines to methylvinylketone with high catalytic efficiency (63–83% yield). A hybrid of α‐amylase with copper nanoparticle (α‐amylase@CuNPs) has been prepared and used to

Carbonyl compounds with a heteroatom at the β carbon are sensitive precursors because they are prone to elimination under different conditions. Morita–Baylis–Hillman (MBH) reaction, although a widespread method for C–C bond formation, has its own limitations. Acrylamide and ketone are such limitations of the MBH reaction. Using them together for an intramolecular MBH (IMBH) reaction on a labile framework
