1-Benzylpiperidine-4-carbonitrile (cas: 62718-31-4) belongs to piperidine derivatives. Piperidine is a metabolite of cadaverine, a polyamine found in the human intestine. Piperidine derivatives bearing a masked aldehyde function in the ε-position are easily transformed into quinolizidine compounds through intramolecular reductive amination.COA of Formula: C13H16N2

Catalytic C(sp2)-C(sp3) Bond Formation of Methoxyarenes by the Organic Superbase t-Bu-P4 was written by Shigeno, Masanori;Hayashi, Kazutoshi;Nozawa-Kumada, Kanako;Kondo, Yoshinori. And the article was included in Organic Letters in 2020.COA of Formula: C13H16N2 This article mentions the following:

The organic superbase catalyst t-Bu-P4 achieves nucleophilic aromatic substitution of methoxyarenes with alkanenitrile pronucleophiles. A variety of functional groups [cyano, nitro, (non)enolizable ketone, chloride, and amide moieties] are allowed on methoxyarenes. Moreover, an array of alkanenitriles with/without an aryl moiety at the nitrile α-position can be employed. The system also features no requirement of a stoichiometric base, MeOH (not salt waste) formation as a byproduct, and the production of congested quaternary carbon centers. In the experiment, the researchers used many compounds, for example, 1-Benzylpiperidine-4-carbonitrile (cas: 62718-31-4COA of Formula: C13H16N2).
