Synthetic Exploration of alpha-Diazo gamma-Butyrolactams

DIazo transfer reaction onto -butyrolactams (activated by -ethyloxalylation) gave rare -diazo -butyrolactams. Decomposition of the latter by Rh-2(OAc)(4) in the presence of alcohols and water gave products of O-H insertion of the respective metal-cabene species. Silver triflate (1 mol-%) was found to convert the -butyrolactams investigated into 1,5-dihydro-2H-pyrrol-2-ones which represent versatile building blocks. Particular instability was noted for -diazo -butyrolactams bearing alkyl or o-substituted aryl substituents on the nitrogen atom. These were found to dimerize in solution or upon storage at room temperature to give fully conjugated bis-hydrazones along with the loss of a nitrogen molecule.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 1205-17-0. Computed Properties of https://www.ambeed.com/products/1205-17-0.html.

Catalytic hydrocyanation of alpha-ketoalkynes by Ni(CN)(2)/CO/KCN system in alkaline aqueous media: Identification of the active species

5-Hydroxy-3-pyrrolin-2-ones are regioselectively synthesized in a good yield under very mild conditions by tetracyanonickelate (0) ion catalyzed hydrocyanation of alpha-ketoalkynes, in the absence of hydrogen cyanide. The catalyst is prepared in situ in a basic aqueous medium by reduction of Ni(CN)(2) with CO in the excess of KCN. From the LR spectroscopy studies and by evaluation of catalytic activity of some cyanonickelates it is proposed that [Ni(CN)(4)](-4) anion is the active species in the process. A possible mechanism is suggested for the conversion of nickel cyanide to [Ni(CN)(4)](-4). The effect of the reaction variables, e.g.: reaction time, temperature, absorption of carbon monoxide, the concentration of potassium cyanide, water, substrate, and sodium hydroxide were also examined.

P5CS expression level and proline accumulation in the sensitive and tolerant wheat cultivars under control and drought stress conditions in the presence/absence of silicon and salicylic acid

The effects of silicon (Si) and salicylic acid (SA) applications on proline content and expression of (1)-pyrrolin-5-carboxylate synthetase (P5CS) were examined under different drought levels and different drought exposure times. Two wheat cultivars, a drought tolerant and a drought sensitive were used. The experiment was a factorial based on completely randomized design with three replicates. Expression analysis by the quantitative real time PCR showed that the tolerant cultivar had significantly higher P5CS expressions compared to the sensitive one under drought stress. In sampling time points, the maximum level of mRNA was observed at 48h after stress was applied. At 48h after stress induction, the expression of P5CS was almost 3.1 fold higher in the tolerant cultivar compared to the sensitive one. In both cultivars, gene expression decreased from 48 to 72h. The stressed plants treated with Si+SA showed a higher expression. Proline content started to increase by Si and SA treatments and the maximum proline content was obtained at simultaneous application of Si+SA. Drought stress significantly reduced chlorophyll content, relative water content and leaf water potential of both cultivars, while increased electrolyte leakage (EL) of the leaves. In contrast, foliar-applied Si and SA significantly increased these parameters and reduced EL, and the effect of simultaneous application of Si and SA was greater. The results suggest that the P5CS is a stress inducible gene. This gene has the potential to be used for improvement of drought stress tolerance in wheat. Network analysis highlighted positive interaction of osmotic stress, drought and cold stress on P5CS1 and the regulatory role of MYB2, ERF-1, and EIN3 transcription factors. In conclusion, alleviation of drought stress by application of Si and SA was associated partially with enhanced expression of P5CS gene and following proline accumulation.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 1205-17-0, you can contact me at any time and look forward to more communication. Application In Synthesis of 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde.

Computational exploration of the 1,3-dipolar cycloaddition reaction of 7-isopropylidenebenzonorbornadiene with nitrile oxide and cyclic nitrone derivatives

The synthesis of isoxazolidine and isoxazole derivatives, versatile building blocks for the construction of a wide range of complex heterocyclic architectures in synthetic organic and medicinal chemistry, is efficiently achieved via the 1,3-dipolar cycloaddition reaction (1,3-DC). Herein, we report an extensive theoretical study on the peri-, regio-, stereo, and enantio-selectivities of 1,3-DC of 7-isopropylidenebenzonorbornadiene with nitrile oxide and cyclic nitrone derivatives using density functional theory calculations. Acetophenone-substituted nitrile oxide periselectively adds across the endocyclic olefinic bond of the dipolarophile to furnish the exo-cycloadduct as the major product, a reaction that has a rate constant of 1.88 x 10(9) s(-1). The endo approach of this periselective path is the closest competing pathway with a rate constant of 4.59 x 10(7) s(-1). Different substituents on the nitrile oxide do not affect the peri- and stereo-selectivity of the reaction. Diethyl ether solvation has no substantial effect on the energetic patterns observed in the gas phase computation. Also, we report a novel 1,3-DC between cyclic nitrone derivatives and 7-isopropylidenebenzonorbornadiene as an efficient way to generate isoxazolidine derivatives. Even though the reactions of the cyclic nitrone derivatives have slightly higher activation barriers than the acyclic nitrile oxide derivatives, the former is more enantioselective than the latter. Whereas electron-donating groups (EDGs) on the cyclic nitrone favor the formation of the exo-cycloadduct, electron-withdrawing groups (EWGs) favor the formation of the endo-cycloadduct. Both 1,3-dipoles add across the dipolarophile via a concerted asynchronous mechanism.

Preparation of Amorphous Poly(aryl ether nitrile ketone) and Its Composites with Nano Hydroxyapatite for 3D Artificial Bone Printing

PEEK had been used to fabricate artificial bones by 3D printing widely, but it expressed unsatisfactory interlayer performance of 3D printing and weak compatibility with nano hydroxyapatite(nHA) due to the limits of molecular structures. Here an amorphous poly(aryl ether ketone) for 3D bone printing, PEK-CN, was designed and synthesized via nucleophilic substitution from 4,4′-difluorobenzophenone, phenolphthalein and 2,6-dichlorobenzonitrile, which possessed much stronger interlayer strength due to van der Waals force between polar groups(-CNs). Specifically, the stronger interlayer strength resulted in lower porosity(3% with 100% infill rate) and more comparable mechanical properties(the maximum tensile strength was similar to 110 MPa) to cortical bone. Importantly, PEK-CN had passed in vitro cytotoxicity testing and samples of human mandible and maxillary bones based on PEKCN were printed by fused deposition modeling(FDM) successfully. Moreover, PEK-CN/nHA composites were obtained to enhance bioactivity of resin, and PEK-CN without limits of crystal lattices expressed excellent compatibility with nano hydroxyapatite. Our work provided a high performance resin for 3D bone printing, which would bring better solutions for artificial bone materials.
