Alternative Reactivity of Leucine 5-Hydroxylase Using an Olefin-Containing Substrate to Construct a Substituted Piperidine Ring

Applying enzymatic reactions to produce useful molecules is a central focus of chemical biology. Iron and 2-oxoglutarate (Fe/2OG) enzymes are found in all kingdoms of life and catalyze a broad array of oxidative transformations. Herein, we demonstrate that the activity of an Fe/2OG enzyme can be redirected when changing the targeted carbon hybridization from sp(3) to sp(2). During leucine 5-hydroxylase catalysis, installation of an olefin group onto the substrate redirects the Fe(IV)-oxo species reactivity from hydroxylation to asymmetric epoxidation. The resulting epoxide subsequently undergoes intramolecular cyclization to form the substituted piperidine, 2S,5S-hydroxypipecolic acid.

Electric Literature of 19916-73-5, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 19916-73-5.

Perinatal hypoxic-ischemic brain injury in large animal models: Relevance to human neonatal encephalopathy

Perinatal hypoxia-ischemia resulting in death or lifelong disabilities remains a major clinical disorder. Neonatal models of hypoxia-ischemia in rodents have enhanced our understanding of cellular mechanisms of neural injury in developing brain, but have limitations in simulating the range, accuracy, and physiology of clinical hypoxia-ischemia and the relevant systems neuropathology that contribute to the human brain injury pattern. Large animal models of perinatal hypoxia-ischemia, such as partial or complete asphyxia at the time of delivery of fetal monkeys, umbilical cord occlusion and cerebral hypoperfusion at different stages of gestation in fetal sheep, and severe hypoxia and hypoperfusion in newborn piglets, have largely overcome these limitations. In monkey, complete asphyxia produces preferential injury to cerebellum and primary sensory nuclei in brainstem and thalamus, whereas partial asphyxia produces preferential injury to somatosensory and motor cortex, basal ganglia, and thalamus. Mid-gestational fetal sheep provide a valuable model for studying vulnerability of progenitor oligodendrocytes. Hypoxia followed by asphyxia in newborn piglets replicates the systems injury seen in term newborns. Efficacy of post-insult hypothermia in animal models led to the success of clinical trials in term human neonates. Large animal models are now being used to explore adjunct therapy to augment hypothermic neuroprotection.

Application of highly efficient and reusable H3PW12O40/Fe3O4@SiO2-Pr-Pi nanocatalyst for preparation of dihydro-2-oxypyrrole derivatives

In this study, a novel heterogeneous catalyst (H3PW12O40/Fe3O4@SiO2-Pr-Pi) was prepared via immobilization of H3PW12O40 on the surface of piperidine modified magnetic nanoparticles (Fe3O4@SiO2-Pr-Pi). The synthesis of dihydro-2-oxypyrrole derivatives was carried out by the reaction of substituted aniline, formaldehyde, and dimethyl acetylenedicarboxylate, promoted by H3PW12O40/Fe3O4@SiO2-Pr-Pi in EtOH. The formation of resultant catalyst was confirmed by FTIR spectroscopy, FE-SEM, EDX, VSM, and TGA techniques. The magnetically separable and environmentally friendly nanostructured catalyst remained quite stable during reaction conditions and was reused for at least five recycle runs.

Quality and quantity of piperidine alkaloids in needles and bark of Scots pine (Pinus sylvestris) seedlings

The Northern boreal forest zone is dominated by two coniferous species that synthesize piperidine alkaloids: Scots pine (Punts sylvestris) and Norway spruce (Picea abies). These compounds are known to have antifeedant properties. We have earlier shown that Norway spruce has a diverse alkaloid chemistry, but reports from P. sylvestris are few, and no quantitative analysis has been conducted so far. Here we have studied 2-year-old seedlings of P. sylvestris to reveal possible differences in alkaloid chemistry compared to P. abies. Alkaloids were extracted from bark and mature needles by solid-phase partitioning and analysed by GC-MS. We detected only four individual compounds from P. sylvestris samples, confirming earlier assumptions that the species lacks large parts of the biosynthesis pathway of coniferous alkaloids. Euphococcinine, also present in mature P. abies needles, is the sole end-product of alkaloid biosynthesis in P. sylvestris, although a compound tentatively identified as an isomer of euphococcinine was also detected. The two other alkaloid compounds detected are also encountered in P. abies, but only in juvenile plant parts, such as developing needles and stems. Concentrations of all alkaloids were extremely low, with totals amounting to about 25% of the amount found in P. abies. It is also notable that concentrations in three out of ten seedlings were under the detection limit, in bark or in both plant parts, whereas in P. abies individuals lacking alkaloids are virtually non-existent. The compound composition, concentrations and absence of alkaloids in some individuals emphasize the difference between these two major boreal zone species, and this calls for further studies on the ecological significance of these compounds.

Chan-Lam cross-coupling reaction based on the Cu2S/TMEDA system

A catalyst based on the readily available Cu2S/TMEDA system using a stable copper(I) source was developed for the Chan-Lam cross-coupling reaction. The capability of the catalyst was demonstrated with 1H-benzo[d]imidazol-2(3H)-one, 1H-benzo[dlimidazole, and 1H-imidazole together with electron deficient, electron-rich, and sterically demanding boronic acids at room temperature in the presence of atmospheric oxygen to give the cross-coupling products in moderate to excellent yields. In addition, the coupling reaction of 1H-benzo[dlimidazole with several pinacol or neopentylglycol boronates indicated further potential of the catalyst. The reaction conditions tolerate the hydroxyl and bromo functional groups. The catalytic system also enables to synthesize the mono-N-substituted anilines from primary aliphatic amines. However, the two model compounds for the secondary and aromatic amines, piperidine and aniline, do not react. Two sterically demanding products with the restricted C-N bond rotation, synthesized by the N-arylation of 1H-benzo[d]imidazol-2(3H)-one with o-tolylboronic acid, enabled to confirm the atropisomers prepared by the Chan-Lam cross-coupling reaction. Furthermore, an example of one-pot Chan-Lam and Suzuki-Miyaura reaction has been reported. (C) 2017 Elsevier Ltd. All rights reserved.

One-Pot Synthesis and Antioxidant Properties of Highly Substituted Piperidine Derivatives Promoted by Choline Chloride/Urea

The simple pseudo four-component reaction of 2,7-naphthalenediol, tow molecules of aldehydes and ammonum carboxylates to produce a series ofN-acylated and non-acylated highly substituted piperidine derivatives has been carried out in the presence of choline chloride/urea at 80 degrees C. One-pot reaction, high efficiency, appropriate reaction time, and easy purification of products by simple recrystallization are some of the considerable advantages of this procedure. The produced highly substituted piperidine derivatives were screened for their antioxidant property. The results indicated that the highly substituted piperidine derivative4hhad higher antioxidant properties.

The synthesis of 3-azabicyclo[4.3.0]nonane scaffolds from brefeldin A

Brefeldin A (BFA) is a fungal metabolite that displays a wide range of biological activities making it an attractive target for drug discovery. To explore the biological potential of the BFA scaffold an amine-macrocycle target 3 was proposed. To access, we dissembled BFA into smaller building blocks in preparation for regenerating the macro-lactone. These entities can then be used to synthesise new brefeldin analogues with various new structural features for biological testing. To overcome supply issues a scaled fermentation process of Penicillium camemberti was employed generating 4.5 kg of BFA. Novel N-BFA type derivatives were generated and herein we describe the synthesis of two new scaffolds 12 and 14 from BFA over six steps in 24% and 17% yield, respectively. A trans-fused bicyclic cyclopentanoid piperidine scaffold 16 can be generated from 12 that may serve as a valuable new scaffold for the synthesis of novel natural product-like compounds.
