In some cases, the catalyzed mechanism may include additional steps.In a article, 2403-89-6, molcular formula is C10H21NO, introducing its new discovery. Computed Properties of C10H21NO

In this work pyrolysis-GC/MS studies are presented on two pairs of hindered amine light stabilisers (HALS) oligomers and polymers. Pyrolysis has been performed in the temperature range from 300 to 900C, also in the presence of PVC in order to observe the possible effect of this hardly avoidable plastic waste component on the production of volatiles from HALS compounds. Intramolecular rearrangement of ester segments of the macromolecular chain leads to succinic acid anhydride and 1-azacyclohexeneethanol in Tinuvin 622 already at 400C. In the presence of PVC 1-azacyclohexenechloroethane is also formed from this stabiliser. The piperidine moieties bound to the macromolecular core by ester bonds are cleaved through unimolecular beta-elimination reaction at around 500C. Thermal decomposition of HALS composed of only amines starts at higher temperatures and proceeds through the scission of C-N bonds. Alkenes are cleaved from secondary amino groups more easily than from tertiary ones. The scission of the pirimidine ring leads to alkylenamines, alkadienes and trienes at above 600C. In the presence of PVC the formation of alkylenamines is depressed. By C-C bond cleavage volatile products originating from alkyl side groups or hindered phenolic moieties also appear in the pyrolysate. Aromatisation of the piperidine rings with methane loss takes place at above 700C leading to 2,6-dimethylpyridine, 2,6-dimethylanilines and 1,3-dimethylbenzene. In the presence of PVC the formation of pyridine and aniline compounds are depressed. At 900C volatile alkane- and alkenenitriles evolve together with traces of hydrogen cyanide. The formation of hydrogen cyanide is enhanced in the presence of PVC.

The optimisation of a ligand-exchange approach to catalytic asymmetric deprotonation of O-alkyl carbamates and subsequent electrophilic trapping (the ‘Hoppe reaction’) is presented. The method uses s-BuLi and sub-stoichiometric amounts of a chiral diamine [(-)-sparteine or the (+)-sparteine surrogate] in conjunction with an achiral ‘regenerating’ diamine (bisisopropyl bispidine) for the deprotonation and proceeds with good yields (up to 84%) and high enantioselectivity (up to 94:6 er). The first applications of this catalytic asymmetric deprotonation methodology in natural product synthesis are also described. Georg Thieme Verlag Stuttgart.

Electric Literature of 2008-75-5, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.2008-75-5, Name is 1-(2-Chloroethyl)piperidine hydrochloride, molecular formula is C7H15Cl2N. In a Article，once mentioned of 2008-75-5

A series of novel benzimidazoles (BI) derived from the indole 2 was synthesized and evaluated as selective neuropeptide Y (NPY) Y1 receptor antagonists with the aim of developing antiobesity drugs. In our SAR approach, the (4-chlorophenoxy)methyl group at C-2 was kept constant and a series of BIs substituted with various piperidinylalkyl groups at N-1 was synthesized to identify the optimal spacing and orientation of the piperidine ring nitrogen relative to the benzimidazole. The 3-(3-piperidinyl)propyl in 33 was found to maximize affinity for the Y1 receptor. Because of the critical importance of Arg33 and Arg35 of NPY binding to the Y1 receptor, the incorporation of an additional aminoalkyl functionality to the structure of 33 was explored. Methyl substitution was used to probe where substitution on the aromatic ring was best tolerated. In this fashion, the C-4 was chosen for the substitution of the second aminoalkyl functionality. Synthesis of such compounds with a phenoxy tether using the 4-hydroxybenzimidazole 11 was pursued because of their relative ease of synthesis. Functionalization of the hydroxy group of 45 with a series of piperidinylalkyl groups provided the dibasic benzimidazoles 55-62. Among them, BI 56 demonstrated a K(i) of 0.0017 muM, which was 400-fold more potent than 33. To evaluate if there was a stereoselective effect on affinity for these BIs, the four constituent stereoisomers (69-72) of the BI 60 were prepared using the S- and R-isomers of bromide 17. Antagonist activity of these BIs was confirmed by measuring the ability of selected compounds to reverse NPY-induced forskolin-stimulated cyclic AMP. The high selectivity of several BI antagonists for the Y1 versus Y2, Y4, and Y5 receptors was also shown.
