Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 134441-93-3, molcular formula is C11H21NO3, introducing its new discovery. HPLC of Formula: C11H21NO3

Here we report the synthesis of all four stereoisomers of mefloquine. Mefloquine (Lariam) is an important anti-malaria drug that is applied as a racemate of the erythro form. However, the (-)-isomer induces psychosis, while the (+)-enantiomer does not have this undesired side effect. There are six syntheses of which five lead to the wrong enantiomer without the authors of these syntheses noting that they had synthesized the wrong compound. At the same time physical chemistry investigations had assigned the absolute configuration correctly and the last enantioselective synthesis that took these results into account delivered the correct absolute configuration. Since various synthetic approaches failed to provide the correct stereoisomers in previous syntheses, we submit here a synthetic approach with a domino Sonogashira-6pi- electrocyclisation as key step that confirmed synthetically the correct absolute configuration of all four isomers. Five to four: A total synthesis that yields all four stereoisomers of the important antimalarial drug mefloquine (Lariam) has been developed. This five-step approach with a domino Sonogashira-6pi- electrocyclisation as key step has confirmed synthetically the correct absolute configuration of all four isomers (see scheme).

Although dimeric natural products can often be synthesized in the laboratory by directly merging advanced monomers, these approaches sometimes fail, leading instead to non-natural architectures via incorrect unions. Such a situation arose during our studies of the coccinellid alkaloids, when attempts to directly dimerize Natures presumed monomeric precursors in a putative biomimetic sequence afforded only a non-natural analogue through improper regiocontrol. Herein, we outline a unique strategy for dimer formation that obviates these difficulties, one which rapidly constructs the coccinellid dimers psylloborine A and isopsylloborine A through a terminating sequence of two reaction cascades that generate five bonds, five rings, and four stereocenters. In addition, a common synthetic intermediate is identified which allows for the rapid, asymmetric formal or complete total syntheses of eight monomeric members of the class.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.134441-93-3,(S)-1-Boc-2-(Hydroxymethyl)piperidine,as a common compound, the synthetic route is as follows.

General procedure: To a solution of (COCl)2 (1.2mmol) in DCM (10mL) cooled to -78C was added DMSO (1.5mmol). The carbamate protected pipecolinol 10 (a, b, c) (1mmol) was then added drop wise over a period of 5min. The reaction mixture was brought to -50C in 15min and Et3N (3mmol) was added over a period of 5min. It was then stirred for 10min at the same temperature and further stirred at rt for 15min. The reaction mixture was further diluted with DCM (10mL) and the organic layer was washed with very dil HCl (0.1N, 10mL¡Á2) and brine solution (10mL¡Á2). It was then dried over anhyd Na2SO4 and concentrated under reduced pressure to afford aldehyde 11 (a, b, c) as a thick liquid, which without any further purification was immediately consumed for the next reaction.
