A number of new 10-oxa-13-aza, 11-oxa-13-aza, and 9-oxa-7-aza prostanoids belonging to the B series were synthesized on the basis of 3-acyl- and 3-(3-arylprop-2-enoyl)furan-2,4(3H,5H)-diones. The scheme of synthesis includes selective hydrogenation of the exocyclic carbonyl group and reduction of the conjugated double bond in the acyl fragment of 3-acyl- and 3-(3-arylprop-2- enoyl)furan-2,4(3H,5H)-diones to obtain 3-alkyl- and 3-(3-arylpropyl)furan-2, 4(3H,5H)-diones, transformation of the latter into the corresponding regioisomeric enol ethers via regioselective O-alkylation, and treatment of the enol ethers with primary aliphatic amines.

Described herein are compounds and pharmaceutical compositions containing such compounds which inhibit transglutaminase 2 (TG2). Also described herein are methods for using such TG2 inhibitors, alone or in combination with other compounds, for treating diseases or conditions that would benefit from TG2 inhibition.

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.SDS of cas: 21461-84-7, you can also check out more blogs about21461-84-7

4100-80-5, Name is 3-Methyldihydrofuran-2,5-dione, belongs to tetrahydrofurans compound, is a common compound. COA of Formula: C5H6O3In an article, once mentioned the new application about 4100-80-5.

As manned space missions extend in length, the safety, nutrition, acceptability, and shelf life of space foods are of paramount importance to NASA. Since food and mealtimes play a key role in reducing stress and boredom of prolonged missions, the quality of food in terms of appearance, flavor, texture, and aroma can have significant psychological ramifications on astronaut performance. The FDA, which oversees space foods, currently requires a minimum dose of 44 kGy for irradiated space foods. The underlying hypothesis was that commercial sterility of space foods could be achieved at a significantly lower dose, and this lowered dose would positively affect the shelf life of the product. Electron beam processed beef fajitas were used as an example NASA space food to benchmark the minimum eBeam dose required for sterility. A 15 kGy dose was able to achieve an approximately 10 log reduction in Shiga-toxin-producing Escherichia coli bacteria, and a 5 log reduction in Clostridium sporogenes spores. Furthermore, accelerated shelf life testing (ASLT) to determine sensory and quality characteristics under various conditions was conducted. Using Multidimensional gas-chromatography?olfactometry?mass spectrometry (MDGC-O-MS), numerous volatiles were shown to be dependent on the dose applied to the product. Furthermore, concentrations of off ?flavor aroma compounds such as dimethyl sulfide were decreased at the reduced 15 kGy dose. The results suggest that the combination of conventional cooking combined with eBeam processing (15 kGy) can achieve the safety and shelf-life objectives needed for long duration space-foods.

Chemistry is traditionally divided into organic and inorganic chemistry. Computed Properties of C5H10O2, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 15833-61-1

Tetrahydrofurans functionalized at the C2 or C3 position (alcohols, esters, amine, ether, acetal) are cleaved with RCOCl/NaI (R = Me, tBu) in acetonitrile to give regioselectively trifunctionalized derivatives. In all cases the cleavage occurs mainly or exclusively at the C-O bond the most remote from the functional group.

(Chemical Equation Presented) A fast and acid-free one-pot 0.2-30 mmol microwave methodology for direct ionic liquid-mediated preparation of lactams from lactones and primary amines has been developed. The protocol was investigated with a wide range of primary amines and a handful of lactones, including substrates with acid-sensitive substituents. Both gamma-lactams and delta-lactams were, despite the complete absence of a Bronsted acid, obtained in useful to excellent yields after only 35 min of microwave processing.

5-Hydroxymethylfurfural (HMF) is a very valuable platform molecule obtained from biomass. It can be catalytically transformed to many industrially relevant products of both oxidation and reduction reactions. In this work, we showed that robust CuZnO can be an efficient, self-tuned catalyst for 2,5-dimethylfuran (DMF) (biofuel additive) synthesis. We showed that CuZnO catalysts can be further activated in the reaction environment and this process depends strongly on the initial catalyst properties and therefore on the catalyst preparation method. Smaller copper particles are more active but more prone to carbon deposit formation. Based on activity tests and extensive characterization, we have concluded that both Cun+ and Cu0 sites are necessary for high HMF conversion. While these two sites favor high conversion and high 2,5-bishydroxymethylfuran (BHMF) yield, the in situ formation of Lewis acid sites is proposed to be necessary for achieving a high DMF yield.
