Piperidine was first reported in 1850 by the Scottish chemist Thomas Anderson and again, independently, in 1852 by the French chemist 5382-16-1, formula is C5H11NO, Name is 4-Piperidinol. Auguste Cahours, who named it. Both of them obtained piperidine by reacting piperine with nitric acid. Formula: C5H11NO.

P.;Duarte, Fernanda;Choi, Chulho;Mousseau, James J.;Bull, James A. research published 《 Amino-oxetanes as amide isosteres by an alternative defluorosulfonylative coupling of sulfonyl fluorides》, the research content is summarized as follows. A class of reactions for sulfonyl fluorides to form amino-oxetanes by an alternative pathway to the established SuFEx (sulfonyl-fluoride exchange) click reactivity. A defluorosulfonylation forms planar oxetane carbocations simply on warming. This disconnection, comparable to a typical amidation, will allow the application of vast existing amine libraries. The reaction was tolerant to a wide range of polar functionalities and was suitable for array formats. Ten oxetane analogs of bioactive benzamides and marketed drugs were prepared Kinetic and computational studied support the formation of an oxetane carbocation as the rate-determining step, followed by a chemoselective nucleophile coupling step.
Formula: C5H11NO, 4-Hydroxypiperidine is a molecule with a carbonyl group. It is the most active and selective CCR5 receptor antagonist that has been studied to date. 4-Hydroxypiperidine inhibits HIV infection by preventing the binding of HIV to its receptor on the surface of white blood cells, thereby preventing it from entering these cells. 4-Hydroxypiperidine also acts as an anti-inflammatory agent in chronic bronchitis patients, due to its ability to inhibit prostaglandin synthesis. The chemical ionization mass spectra of this molecule show peaks for methyl ethyl, malic acid, and hydroxyl groups. These properties make 4-hydroxypiperidine a useful candidate for drug development against inflammatory diseases and several cancers.
The molecular structure, vibrational spectra, NBO and UV-spectral analysis of 4-Hydroxypiperidine have been studied. The compounds with a substituted 4-piperidinol core have been found to be potent antagonists of the human H receptor., 5382-16-1.
