A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Computed Properties of C6H13NO, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 3433-37-2, Name is 2-(Hydroxymethyl)piperidine, molecular formula is C6H13NO. In a Article, authors is Lovely, Ann E.，once mentioned of 3433-37-2

(Chemical Equation Presented) Enantiomeric discrimination is observed in the 1H and 13C NMR spectra of piperidines and piperazines in the presence of (-)-(18-crown-6)-2,3,11,12-tetracarboxylic acid. The amines are protonated by the carboxylic acid groups of the crown ether to produce the corresponding ammonium and carboxylate ions. Association of the ammonium ion with the crown ether likely involves two hydrogen bonds with the crown ether oxygen atoms and an ion pair with the carboxylate anion. Methyl, hydroxymethyl, phenyl, carboxyl, pyridyl, and cyclohexyl substituent groups alpha to the nitrogen atom do not inhibit binding of the ammonium ion to the crown ether. The NMR spectra of piperidines with the stereogenic center alpha or beta to the nitrogen atom exhibit substantial enantiomeric discrimination. Dibasic substrates such as the piperizines are likely converted to their diprotonated form in the presence of the crown ether, and both nitrogen atoms appear to associate with the crown ether moiety.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Quality Control of: 1-Aminopiperidine, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 2213-43-6, Name is 1-Aminopiperidine, molecular formula is C5H12N2. In a Article, authors is Ghavtadze, Nugzar，once mentioned of 2213-43-6

(Chemical Equation Presented) Trifluoromethyl-substituted 1-amino-1-azapenta-1,4-dien-3-ones 4, which are accessible in good yield from pyruvates 1 in a three-step procedure, undergo a cascade reaction involving inter alia two electrocyclizations upon treatment with a large excess of trifluoromethanesulfonic acid to give novel dihydrospiroindenepyrazole 5a-o and dihydroindenodiazepine 6a-j. We interpret this sequence of reactions on the basis of quantum chemical calculations as a dicationic cyclization of a pentadien-1-one (“superelectrophilic solvation”), where one of the double bonds is part of an aromatic ring and a subsequent rearrangement to form an (monocationic) iminium ion, which either cyclizes to give five-membered spiro ring systems (compounds 5) or tricyclic dihydroindenodiazepine derivatives 6. Hueckel- and Moebius-type transition states of the electrocyclization reactions are discussed considering the results of NICS calculations. One 1-amino-1-penta-1,4-dien-3-one 4 and several dihydrospiroindenepyrazoles 5 and dihydroindenodiazepines 6 could be characterized by X-ray diffraction.

We examine the relationship between covalent structure and conformational propensity among a series of beta-amino acid tetramers. These experiments focus on the hairpin folding motif. Among conventional peptides, the minimum increment of beta-sheet secondary structure is a ‘beta-hairpin,’ in which two strands are connected via a short loop. The present studies are aimed at optimizing hairpin stability among beta-peptides. Previous work from our laboratory has identified optimal substitution patterns for residues that form strands in an antiparallel beta-peptide sheet (Krauthauser et al. J. Am. Chem. Soc. 1997, 119, 11719), and we have shown that a dinipecotic acid segment can promote sheet-type interactions between attached strand residues (Chung et al. J. Am. Chem. Soc. 1998, 120, 10555). Here we compare all four possible configurations of the dinipecotic acid segment, (R,S), (S,R), (R,R) and (S,S), for the ability to induce sheet formation with a constant set of enantiomerically pure strand residues. We show that both heterochiral dinipecotic acid segments promote hairpin formation, although one is distinctly superior. Neither of the homochiral dinipecotic acid supports hairpin folding. When the strand residues are beta-alanine (achiral), the heterochiral dinipecotic acid segment is again superior to the homochiral segment, but we find a difference between hairpin conformations in solution and in the solid state.

Noninvasive methods to modulate G protein-coupled receptors (GPCRs) with temporal and spatial precision are in great demand. Photopharmacology uses photons to control in situ the biological properties of photoswitchable small-molecule ligands, which bodes well for chemical biological precision approaches. Integrating the light-switchable configurational properties of an azobenzene into the ligand core, we developed a bidirectional antagonist toolbox for an archetypical family A GPCR, the histamine H3 receptor (H3R). From 16 newly synthesized photoswitchable compounds, VUF14738 (28) and VUF14862 (33) were selected as they swiftly and reversibly photoisomerize and show over 10-fold increased or decreased H3R binding affinities, respectively, upon illumination at 360 nm. Both ligands combine long thermal half-lives with fast and high photochemical trans-/cis conversion, allowing their use in real-time electrophysiology experiments with oocytes to confirm dynamic photomodulation of H3R activation in repeated second-scale cycles. VUF14738 and VUF14862 are robust and fatigue-resistant photoswitchable GPCR antagonists suitable for spatiotemporal studies of H3R signaling.
