C-glycosides by aqueous condensation of beta-dicarbonyl compounds with unprotected sugars

Condensation of 1,3-diketones with unprotected aldoses in water, under mildly alkaline conditions, provides a convenient and effective route to C-glycosidic ketones in high yields. Reactions usually proceed with high beta-‘anomeric’ stereoselectivity because product composition is determined by thermodynamic control. Mechanistically, the condensation follows a typical Knoevenagel scheme, after which an intramolecular oxa-Michael cyclization determines C-glycoside configuration by following an exo- or endo-trig pathway. With open-chain 1,3-diketones, an ensuing retro-Claisen fragmentation occurs to furnish simple glycosyl monoketones. The C-glycosides then slowly further dehydrate under the reaction conditions to give 2,5-disubstituted furans.

Highly selective formation of beta-glycosides of N-acetylglucosamine using catalytic iron(III) Triflate

Efficient and highly selective glycosylation reactions of peracetylated beta-D-N-acetylglucosamine are described using catalytic iron(III) triflate and 2,4,6-tri-tert-butylpyrimidine (TTBP) under microwave conditions. We have demonstrated that the formation of beta-(1?6) and beta-(1?3) linked disaccharides are obtained in high yields in the presence ofvarious protecting groups.

Subtlety of the spin-crossover phenomenon observed with dipyridylamino-substituted triazine ligands

Reactions of the new, closely related ligands 4,6-dichloro- N,N-di(pyridine-2-yl)-1,3,5-triazine-amine (Cldpat) and 6- chloro-N’-phenyl-N,N- di(pyridin-2-yl)-1,3,5-triazine-2,4-diamine (Cladpat) with iron(II) thiocyanate produced coordination compounds with drastically distinct magnetic properties. The compound trans-[Fe(Cldpat)2(NCS)2](H2O) (1) is a highspin complex from room temperature down to 5 K whereas the analogous compound trans-[Fe(Cladpat) 2 (NCS) 2] (2) exhibits spin-crossover (SCO) properties with T1/2 = 178K. Compounds 1 and 2 (both in its low-spin and high-spin states) have been structurally characterized by X-ray diffraction studies, which revealed identical metal coordination spheres. The SCO properties of 2 have been thoroughly investigated by temperature-dependent magnetic susceptibility measurements and differential scanning calorimetry (DSC), and a LIESST process with rapid relaxation of the trapped HS species has been observed. The equivalent coordination compound with selenocyanate anions, namely [Fe(Cladpat) 2 (NCSe) 2] (3) also displays SCO properties, although more gradual and with a lower T 1/2 value of 166 K.

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 499-40-1 is helpful to your research., Application of 499-40-1

Distribution of glycolipid and unsaturated fatty acids in human hair

It has been recognized that human hair lipids play crucial roles in the integrity of cells and matrices, while the details of distribution and structure of the minor lipids are hardly known. Here we investigated the lipids at the hair surface, at the interface between cuticle and cortex and in the interior of hair (cortex, medulla and melanin granules). Hair lipids and fatty acids and their metabolites were detected and characterized by using infrared spectroscopy and several mass spectrometry techniques (FTIR, ToF-SIMS, GCMS, and ESI-MS). As a result, it was found that unsaturated fatty acids were present more in the cortex of hair than at the hair surface. At the interface between cuticle and cortex, it is suggested that steryl glycoside-like lipids containing N-acetylglucosamine were present, and contributing to the adhesion between the cuticle and cortex of hair. Oxidative metabolites derived from integral fatty acids such as linoleic and alpha-linolenic acids were found in the hair bulb and melanin granules. Especially the oxidative metabolites of alpha-linolenic acid were integrated into the lipids non-covalently and tightly bound to melanin granules (namely, melanin lipids) and suggested as being involved in the biosynthetic processes of melanosome.
