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
