METHOD OF FLUORINATION

A method of fluorination comprising reacting monosaccharides, oligosaccharides, polysaccharides, composite saccharides formed by bonding of these saccharides with proteins and lipids and saccharides having polyalcohols, aldehydes, ketones and acids of the polyalcohols, and derivatives and condensates of these compounds with a fluorinating agent represented by general formula (I) thermally or under irradiation with microwave or an electromagnetic wave having a wavelength around the microwave region. In accordance with the method, the fluorination at a selected position can be conducted safely at a temperature in the range of 150 to 200C where the reaction is difficult in accordance with conventional methods. The above method comprising the irradiation with microwave or an electromagnetic wave having a wavelength around the microwave region can be applied to substrates other than saccharides. When a complex compound comprising HF and a base is reacted under irradiation with microwave, fluorination at a specific position which is difficult in accordance with conventional methods proceeds highly selectively, efficiently in a short time and safely.

INHIBITION OF TRICHOTHECENE TOXIN BIOSYNTHESIS BY NATURALLY OCCURRING SHIKIMATE AROMATICS

Certain naturally occurring flavonoids and furanocoumarins are inhibitors of trichothecene toxin biosynthesis.These compounds block T-2 biosynthesis in liquid cultures of Fusarium sporotrichioides NRRL 3299 at contcentrations substantially less than required to block fungal growth.Inhibited cultures accumulate variable amounts of trichodiene, the hydrocarbon precursor of the trichothecenes.These inhibitors appear to block the trichothecene biosynthetic pathway after formation of trichodiene and before formation of highly oxygenated trichothecenes.Exposure to these widely occuring plant shikimate aromatics may inhibit trichothecene production during plant pathogenesis.Key Word Index-Umbelliferae; Leguminosae; furanocoumarins; flavonoids; Fusaria; trichothecene toxins.

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: 2081-44-9, you can also check out more blogs about2081-44-9

Synthesis of antioxidative and anti-inflammatory drugs glucoconjugates

Glucoconjugates of (¡À)-ibuprofen, (¡À)-alpha-tocopherol (vitamin E), gentisic acid, gallic acid, 2,6-bis(tert-butyl)-4-thiophenol, and N-acetyl-L-cysteine were prepared with the objective of increasing the bioavailability of such antioxidant and anti-inflammatory drugs. The O-glucosides were synthesized using benzylated alpha-D-glucopyranosyl trichloracetimidate as glycosyl donor. For the synthesis of the S-glucosides, the glycosyl donor 1,2,3,4,6-penta-O-acetyl-beta-D-glucopyranose provided higher yields than the corresponding O-acetylated imidate.

Asymmetric Propargylic Radical Cyanation Enabled by Dual Organophotoredox and Copper Catalysis

The first asymmetric propargylic radical cyanation was realized through a dual photoredox and copper catalysis. An organic photocatalyst serves to both generate propargyl radicals and oxidize Cu(I) species to Cu(II) species. A chiral Cu complex functions as an efficient organometallic catalyst to resemble the propargyl radical and cyanide in an enantio-controlled manner. Thus, a diverse range of optically active propargyl cyanides were produced with high reaction efficiency and enantioselectivities (28 examples, 57-97% yields and 83-98% ee). Moreover, mechanistic investigations including experiments and density functional theory calculations were performed to illustrate on the reaction pathway and stereochemical results.

Preparation and characterization of chitosan/clay composite for direct Rose FRN dye removal from aqueous media: Comparison of linear and non-linear regression methods

In the present study, sorption efficacy of chitosan (beta-(1?4)-linked d-glucosamine and N-acetyl-d-glucosamine) composite for synthetic direct Rose FRN dye removal from aqueous media was investigated. Chitosan and clay were subjected to chemical modifications to prepare chitosan/clay composite. Batch sorption affecting parameters like pH, composite dose, volume, initial dye concentration, time and temperature were optimized. Maximum sorption capacity (17.18 mg/g) was found within first 40 min of contact. Point of zero charge was found to be 7.0. Linearized and non-linearized regression forms of pseudo 1st and 2nd order kinetic models were used to predict the nature of rate limiting steps involved in the sorption process. Sorption equilibrium data was revealed by applying linear and non-linear equilibrium Langmuir, Freundlich and Redlich-Peterson isotherm models. Calculated values of thermodynamic factors showed that sorption process is exothermic, spontaneous and feasible. Desorption studies were performed for the regeneration of chitosan/clay composite by using different eluting agents. The synthesized composite were characterized by X-ray diffraction (XRD), surface analysis (Brunauer, Emmett and Teller: BET), scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). The developed method was also applied on the real textile effluent for the efficient removal of dyes.

Pyrazolo[1,5-a]pyrimidine-based inhibitors of HCV polymerase

The present paper describes a novel series of HCV RNA polymerase inhibitors based on a pyrazolo[1,5-a]pyrimidine scaffold bearing hydrophobic groups and an acidic functionality. Several compounds were optimized to low nanomolar potencies in a biochemical RdRp assay. SAR trends clearly reveal a stringent preference for a cyclohexyl group as one of the hydrophobes, and improved activities for carboxylic acid derivatives.
