1-(4-Nitrophenyl)piperidin-2-one (cas: 38560-30-4) belongs to piperidine derivatives. The piperidine ring can be found not only in more than half of the currently known structures of alkaloids, but also in many natural or synthetic compounds with interesting biological activities. Fluorinated piperidines are also the subject of continued interest in medicinal chemistry, for example in the synthesis of selective dipeptidyl peptidase II (DPP II) inhibitors. Piperidine derivatives are also used in solid-phase peptide synthesis (SPPS) and many degradation reactions.SDS of cas: 38560-30-4

Copper nanoparticles (CuNPs) supported on ZnO are highly active and selective heterogeneous catalyst for the N-arylation of cyclic and acyclic amides (Golberg coupling). The reaction conditions are mild, featuring K3PO4 as a base and N,N鈥?dimethylethylendiamine (DMEDA) as ligand in refluxing acetonitrile. The CuNPs/ZnO catalyst can be recovered and reused in six cycles with only little loss of activity. The methodol. can be successfully scaled up to gram scale without decreasing the catalytic activity. In the experiment, the researchers used many compounds, for example, 1-(4-Nitrophenyl)piperidin-2-one (cas: 38560-30-4SDS of cas: 38560-30-4).
