Copper-catalyzed Addition Reactions of Aromatics and Ketones to 2-Aza-2,4-cyclopentadienone: Facile and Efficient Transformation of Carbonyl-ene-nitriles to 1H-Pyrrolin-2(5H)-ones

Copper-catalyzed reactions of carbonyl-ene-nitriles with carbon nucleophiles, such as aromatics and ketones, afforded pyrrolin-2-ones (gamma-lactam) in excellent yield. The reaction mechanism involves addition reactions with a ketimine moiety of the 2-aza-2,4-cyclopentadienone intermediate, which is formed via hydration of a nitrile moiety followed by dehydrative cyclization.

Magnetic cobalt ferrite nanoparticles functionalized with citric acid as a green nanocatalyst for one-pot three-component sonochemical synthesis of substituted 3-pyrrolin-2-ones

A clean, convenient and facile approach for one-pot ultrasonic assisted synthesis of substituted 3-pyrrolin-2-ones from diethyl acetylenedicarboxylate, aniline and aldehyde derivatives is described. The reactions were carried out in the presence of an efficient, green and reusable acidic nanocatalyst, magnetic cobalt ferrite nanoparticles functionalized with citric acid (CoFe2O4@CA), with high yields under mild conditions. Also, use of ultrasound irradiation made this approach an attractive protocol for the synthesis of these products. The method has been successful in achieving the green chemistry objective. An energy efficient protocol using ultrasound irradiation instead of conventional heating or stirring and use of ethanol as a non-hazardous, inexpensive and green solvent in the one-step reaction against sequential reaction steps thus combining the features of both economic and environmental advantages.

Bacterial profiles and volatile flavor compounds in commercial Suancai with varying salt concentration from Northeastern China

Suancai, a popular traditional fermented cabbage in northeast China, is commonly prepared by the spontaneous fermentation process at a certain salt concentration. The salt can affect the metabolites by affecting the microorganisms during Suancai fermentation. The bacterial community and volatile flavor compounds in commercial Suancai from different regions of Northeastern China at different salt concentrations were investigated using next-generation sequencing and GC-MS. Firmicutes and Cyanobacteria were the dominant phyla in the commercial Suancai, and Lactobacillus, Pediococcus, and Leuconostoc were the dominant genera. Among them, Lactobacillus and Pediococcus were considered as the biomarkers of the low and high salt Suncai, respectively. Eighty-five volatile flavor compounds were detected, and HS exhibited higher contents of volatile flavor compounds than LS. Based on the results of correlation analysis, Pediococcus were highly correlated with the alcohols and nitriles in Suancai. The contents of alcohols and nitriles significantly increased in the Suancai, fermented by Pediococcus pentosaceus. The co-inoculated fermentation of Lactobacillus plantarum and P. pentosaceus could increase the concentrations of alcohols, esters, aldehydes, hydrocarbons, and nitriles in Suancai. This study provides a perspective for understanding the ecology of Suancai fermentation and facilitating the fermentation with multispecies inoculation fermentation at an appropriate salt concentration.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Read on for other articles about 83411-71-6. Formula: https://www.ambeed.com/products/83411-71-6.html.

Synthetic Processes toward Nitriles without the Use of Cyanide: A Biocatalytic Concept Based on Dehydration of Aldoximes in Water

While belonging to the most fundamental functional groups, nitriles represent a class of compound that still raises challenges in terms of an efficient, cost-effective, general and, at the same time, sustainable way for their synthesis. Complementing existing chemical routes, recently a cyanide-free enzymatic process technology based on the use of an aldoxime dehydratase (Oxd) as a biocatalyst component has been developed and successfully applied for the synthesis of a range of nitrile products. In these biotransformations, the Oxd enzymes catalyze the dehydration of aldoximes as readily available substrates to the nitrile products. Herein, these developments with such enzymes are summarized, with a strong focus on synthetic applications. It is demonstrated that this biocatalytic technology has the potential to cross the bridge between the production of fine chemicals and pharmaceuticals, on one hand, and bulk and commodity chemicals, on the other.

Acid promoted dimerization of beta-amino-alpha,beta-unsaturated amides affording bis(functionalized) pyrrolinones

Polysubstituted pyrrolinones were synthesized by the dimerization of 3-amino-2-butenamides via treatment with 0.5 equiv p-TsOH under mild reaction conditions, including oxidation and 1,2-migration of the methyl group. This method is practically advantageous compared to the conventional methods for the preparation of pyrrolinones, because it does not require difficult experimental manipulations and special reagents such as metal catalysts and oxidants. Because the structures of beta-amino-alpha,beta-unsaturated amides can be easily modified by changing the precursors, beta-keto amide and amine, synthesis of diverse pyrrolinones is possible.
