1-Tosylpiperidin-4-one (cas: 33439-27-9) belongs to piperidine derivatives. The piperidine structural motif is present in numerous natural alkaloids. These include piperine, which gives black pepper its spicy taste. Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst. Pyridine can also be reduced to piperidine via a modified Birch reduction using sodium in ethanol.Application of 33439-27-9

Synthetic Approach toward Enantiopure Cyclic Sulfinamides was written by Jersovs, Glebs;Bojars, Matiss;Donets, Pavel A.;Suna, Edgars. And the article was included in Organic Letters in 2022.Application of 33439-27-9 This article mentions the following:

A synthetic approach toward densely substituted enantiopure cyclic sulfinamides possessing up to four consecutive stereogenic centers has been developed based on a completely diastereoselective SN2‘ cyclization/tert-Bu cleavage sequence. Diastereospecific transformation of the obtained scaffold into chiral SVI derivatives such as sulfoximines and sulfonimidamides is demonstrated. In the experiment, the researchers used many compounds, for example, 1-Tosylpiperidin-4-one (cas: 33439-27-9Application of 33439-27-9).
