1-Tosylpiperidin-4-one (cas: 33439-27-9) belongs to piperidine derivatives. Piperidine and its derivatives have become increasingly popular in many synthetic schemes. Piperidine derivatives bearing a masked aldehyde function in the ε-position are easily transformed into quinolizidine compounds through intramolecular reductive amination.Computed Properties of C12H15NO3S

Regioselective Arylboration of Isoprene and Its Derivatives by Pd/Cu Cooperative Catalysis was written by Smith, Kevin B.;Brown, M. Kevin. And the article was included in Journal of the American Chemical Society in 2017.Computed Properties of C12H15NO3S This article mentions the following:

A method for the regioselective arylboration of isoprene and its derivatives is presented. These reactions allow for the synthesis of useful building blocks from simple components. Through these studies, an unusual additive effect with DMAP was uncovered that allows for altered reactivity and the formation of quaternary C centers. The utility of this method is demonstrated toward the formal synthesis of mesembrine. In the experiment, the researchers used many compounds, for example, 1-Tosylpiperidin-4-one (cas: 33439-27-9Computed Properties of C12H15NO3S).
