A range of 3H-indoles and 2H-benzo[b][1,4]thiazines smoothly undergo asymmetric Strecker reaction with ethyl cyanoformate in the presence of a Cinchona alkaloid-based thiourea catalyst at 10 C to give structurally diverse nitrogen-containing heterocycles in good to excellent yields and with excellent ee.

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.category: Tetrahydropyrans, you can also check out more blogs about50675-18-8

Two low-dimensional molybdenum(VI) oxide/organic hybrid materials crystallize hydrothermally from acidic reaction mixtures containing 2,2?-dipyridylamine. The hydrothermal reactions of MoO3, 2,2?-dipyridylamine and H2O in the molar ratio of 1:0.5:600 at 160C for 96 h afford a one-dimensional solid (C10H10N3)2[Mo6O 19] (1) at pH ? 2 and a two-dimensional solid (C10H10N3)2-[Mo8O 25] (2) at pH < 1. The structure of 1 consists of puckered [Mo12O38]4- chains of corner- and edge-sharing {MoO6} octahedra and {MoO5} square pyramids, and interstrand 2,2?-dipyridylammonium ions. The crystal structure of 2 is constructed from [Mo8O25]2- layers separated by interlamellar 2,2?-dipyridylammonium ions. The successful assembly of low-dimensional network structures of 1 and 2 demonstrates the dramatic influence of reaction acidity on the organization of molecular building blocks and construction of solid architectures. The crystal structures of 1 and 2 are stabilized by electrostatic forces and hydrogen bonds between counterions, and pi-pi interactions among 2,2?-dipyridylammonium ions.

Electrocatalytic CO2 reduction to C2 products is a promising technique when compared with the traditionally complicated and energy intensive routes in the industrial process. As an important bulk chemical, it is highly desirable for acetic acid to be produced via a sustainable method. In this work, we prepared N-based Cu(I)/C-doped boron nitride (BN-C) composites for electrocatalytic reduction of CO2 to acetic acid. It was found that the Faradaic efficiency of acetic acid could reach as high as 80.3% with a current density of 13.9 mA cm-2 when 1-ethyl-3-methylimidazolium tetrafluoroborate ([Emim]BF4)-LiI-water solution was used as the electrolyte, which was about 4 times higher than the best value reported in the literature. Detailed studies further indicated that the Cu complex, BN-C, and the electrolyte have an excellent synergistic effect for producing acetic acid. In particular, as a promoter, LiI played a key role in C-C coupling to form acetic acid in the electrocatalytic process. Our study shows a promising way to produce C2 products via electrochemical reduction of CO2 by the combination of composite electrodes and electrolytes with a promoter.

The chemical synthesis of two trisaccharides related to leonoside E and F is reported. The target oligosaccharides were prepared in the form of their p-methoxyphenyl glycosides using a common disaccharide acceptor. All reaction steps were high yielding (>80%) and the stereoselective glycosylations were achieved by activation of the thioglycoside donors using N-iodosuccinimide in the presence of La(OTf)3.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 28244-94-2 is helpful to your research., Electric Literature of 28244-94-2

Hyaluronan (HA) is well known to reside in the extracellular matrix as a water-sorbed macromolecule. The aims of this study were twofold: to investigate the regulation of HA synthesis in keratinocytes, and to develop a method to modulate this regulatory process. We found that N-acetylglucosamine (NAG) increased the production of HA by cultured keratinocytes dose dependently, but had no effect on the production by skin fibroblasts. The effect of NAG in keratinocytes was found to be specific for HA production, as there was no change in sulfated glycosaminoglycan formation. The copresence of NAG with either of two retinoids, retinoic acid (RA) or retinol, exerted a synergistic effect on HA production. To investigate whether human HA synthase (HAS) genes were regulated by NAG or retinoids, total RNA extracted from cells treated with these agents was subjected to Northern blot analysis. We observed that RA and retinol markedly induced the expression of HA synthase-3 (HAS3) mRNA. Moreover, beta-carotene, a provitamin A, influenced HA production and HAS3 gene expression in a manner similar to the retinoids. Conversely, NAG had no effect on the expression of HAS3 transcripts. Pretreatment of cells with RA stimulated the activity of membrane-associated HAS, whereas pretreatment with NAG did not. These results suggest that HA production is regulated by at least two pathways: one involving the regulation of HAS gene expression, and the other independent of such a regulatory effect. Taken together, our findings suggest that NAG is a new modulator of HA synthesis. Copyright
