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.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1205-17-0, in my other articles.

The effects of fiber silane modification on the mechanical performance of chopped basalt fiber/ABS composites

The purpose of this study was to examine the effects of silane coupling agent modifications on the mechanical performance of the basalt fiber (BF)-reinforced acrylonitrile-butadiene-styrene (ABS) composites. Three different silane coupling agents were used. The mechanical properties of the composites were determined by the tensile, flexural, impact tests, and dynamic mechanical analysis (DMA). According to the test results, the tensile strength increased with the use of (3-aminopropyl) triethoxysilane (AP) and 3-(trimethoxysilyl) propylmethacrylate (MA), while the use of (3-glycidyloxypropyl) trimethoxysilane (GP) reduced the tensile strength. All the silane modifications improved the flexural strength and modulus and the highest improvement was achieved with the use of AP. No remarkable difference was observed in impact properties with the use of silane coupling agents. The addition of BF significantly improved the elastic modulus of the ABS regardless of the modification type, while the further improvements were achieved through the use of AP and MA. In brief, AP showed the highest performance among the studied silane coupling agents due to the covalent bond formation between the amino group of AP and the nitrile group of styrene-acrylonitrile (SAN) matrix.

Novel oxidized derivatives of antifungal pyrrolnitrin from the bacterium Burkholderia cepacia K87

The screening of antifungal active compounds from the fermentation extracts of soil-borne bacterium Burkholderia cepacia K87 afforded pyrrolnitrin (1) and two new pyrrolnitrin analogs, 3-chloro-4-(3-chloro-2-nitrophenyl)-5-methoxy-3-pyrrolin-2-one (2) and 4-chloro3-(3-chloro-2-nitrophenyl)-5-methoxy-3-pyrrolin-2-one (3). Pyrrolnitrin showed strong antifungal activity against Rhizoetonia solani but the analogs (2 and 3) were found to be marginally active. The isolates, 2 and 3, are believed to be biodegraded derivatives of pyrrolnitrin.

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. Name: 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde.

A review on pyrolysis of protein-rich biomass: Nitrogen transformation

Pyrolysis of protein-rich biomass, such as microalgae, macroalgae, sewage sludge, energy crops, and some lignocellulosic biomass, produces bio-oil with high nitrogen (N) content, sometimes as high as 10 wt% or even higher. Major nitrogenous compounds in bio-oil include amines/amides, N-containing heterocycles, and nitriles. Such bio-oil cannot be used as fuel directly since the high N content will induce massive emission of nitrogen oxides during combustion. The present review comprehensively summarized the effects of biomass compositions (i.e., elemental, biochemical, and mineral compositions) and pyrolysis parameters (i.e., temperature, heating rate, atmosphere, bio-oil collection/fractionation methods, and catalysts) on the contents of N and the N-containing chemical components in bio-oil. The migration and transformation mechanisms of N during the pyrolysis of biomass were then discussed in detail. Finally, the research gaps were identified, followed by the proposals for future investigations to achieve the denitrogenation of bio-oil.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1205-17-0 help many people in the next few years. COA of Formula: C11H12O3.
