Esterase catalyzed regioselective hydrolyses of acetylated monosaccharides

Deacylations of fully acylated D-glucopyranoses, methyl D-glucopyranosides, 2-acetamido-2-deoxy-D-glucopyranoses glucopyranoses and methyl 2-acetamido-2-deoxy-D-glucopyranosides catalyzed by rabbit serum or the esterase isolated from rabbit serum were investigated. Depending on the structure of the acyl protecting group a high degree of regioselectivity is observed. Products of enzymic hydrolysis followed by intramolecular migrations of acetyl groups are also described.

Immobilization of UDP-Galactose on an Amphiphilic Resin

Nucleotide sugars are activated sugar precursors used by glycosyltransferases to form glycans. Here we report the first examples of resin-bound nucleotide sugars: fluorinated UDP-galactose and UDP-galactose. They were conjugated to a polyethylene glycol resin through the C6 position with an SMCC linker in good to excellent yields. This synthesis represents an efficient method to access resin-bound nucleotide sugars in a modular approach that enables modifications of the sugar or nucleotide before conjugation. The system has been conceived as a new chemistry-based screening system for enzymes that use UDP-galactose.

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 10343-06-3 is helpful to your research., Synthetic Route of 10343-06-3

Multi-component synthesis of peptide-sugar conjugates

Recent years have witnessed a growing interest in the development of new methods for linking sugars to peptides or proteins because natural glycopeptides or neoglycoconjugates with well defined chemical structures are very important tools to study diverse biological phenomena. Herein we report a novel, one-pot, three-component process for the synthesis of peptide-urea conjugates incorporating a hexafluorovaline or an aspartic acid alkyl ester residue under very mild conditions and high yields. The reaction has been exploited for the synthesis of a wide array of structurally diverse peptide-sugar conjugates through a regiospecific four-component, one-pot sequential domino process, by generating the reacting sugar-carbodiimides in situ from readily accessible starting materials.

Radical cyclization continues to be a central methodology for the preparation of natural products containing heterocyclic rings. Hence, some electrochemical results obtained by cyclic voltammetry and controlled-potential electrolysis in the study of electroreductive intramolecular cyclization of ethyl (2S, 3R)-2-bromo-3-propargyloxy-3-(2?,3?,4?,6?-tetra-O-acetyl-beta-D-glucopyranosyloxy) propanoate (1a), 2-bromo-3-allyloxy-3-(2?,3?,4?,6?-tetra-O-acetyl-beta-D-glucopyranosyloxy)propanoate (1b), 2-bromo-[1-(prop-2-yn-1-yloxy)propyl]benzene (1c) and [1-bromo-2-methoxy-2-(prop-2?-yn-1-yloxy)ethyl]benzene (1d) promoted by (1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane)nickel(I), [Ni(tmc)]+, electrogenerated at glassy carbon cathodes in ethanol and ethanol:water mixtures containing tetraalkylammonium salts, are presented. During controlled-potential electrolyses of solutions containing [Ni(tmc)]2+ and bromoalkoxylated compounds (1) catalytic reduction of the latter proceeds via one-electron cleavage of the carbon-bromine bond to form a radical intermediate that undergoes cyclization to afford the substituted tetrahydrofurans.

Diastereoselective substitution of PR3 for CO in carbene(dicarbonyl)-cyclopentadienyl complexes of manganese – Synthesis of (5Mn)- and (RMn)-[Cp(CO)(PR3)Mn=C(OR*)R?] complexes

Chiral carbene complexes [Cp(CO)2Mn=C(OR*)Ph] (4a-e) were prepared by reaction of [Cp(CO)2Mn=C(OAc)Ph] (2) with HOR* [HOR* = 1,2:3,4-di-O-isopropylidene-D-galactopyranose (3a), 2,3,4,6-tetra-O-acetyl-D-galactopyranose (3b), 2,3,4,6-tetra-O-acetyl-D-glucopyranose (3c), (S)- (3d) and (R)-1,2-O-isopropylideneglycerol (3e)]. The replacement of a CO ligand with PTol3 in 4a-e proceeded diastereoselectively to give [Cp(CO)(PTol3)Mn=C(OR*)Ph] (5a-e). The diastereoselectivity increased in the order a, b, c, d: de = 8% (5a), 33% (5b), 70% (5c), > 96% (5d). For (R)-5d the isomer with the (S) configuration at manganese (SMn) was formed predominantly. For (S)-5d, only (RMn,S)-5d was detected (de > 96%). Photolysis of (R)-4d in the presence of phosphites or phosphanes afforded (SMn)-[Cp(CO) (PR3)Mn=C(OR*)Ph] [PR3 = P(OPh)3 (8), P(OMe)3 (9), P(OMe)2Ph (10), P(OMe)Ph2 (11), PPh3 (12), P(C6H4Cl-P)3 (13)] with a de > 96%. Photolysis of (S)-4d in the presence of P(OMe)3 gave (RMn,S)-9. Complex (R)-14 [related to (R)-4d] was obtained from [Cp(CO)2Mn= C(OAc)Tol-p] and 3d. Replacement of CO by PR3 in (R)-14 gave (SMn,R)-[Cp(CO)(PR3)Mn=C(OR*)Tol-p] [R = Tol-p (15), OMe (16), C6H4Cl-P (17)] with a de > 96%. In solution, the PTol3-substituted complex 5d is configurationally stable whereas the P(OMe)3 complex 9 epimerizes slowly at room temperature in CH2Cl2, Et2O, and THF within about one week.

Synthesis of P1-Citronellyl-P2-alpha-D-pyranosyl pyrophosphates as potential substrates for the E. coli undecaprenyl-pyrophosphoryl-N-acetylglucoseaminyl transferase MurG

P1-Citronellyl-P2-alpha-D-pyranosyl pyrophosphates containing alpha-D-N-acetylglucoseaminyl, alpha-D-glucosyl, and alpha-D-N-acetylmuramyl carbohydrates were synthesized and used in substrate specificity studies of the Escherichia coli MurG enzyme. Oxalyl chloride activation of citronellyl phosphate for coupling to alpha-D-pyranose-1-phosphates resulted in markedly improved yields over traditional Khorana-Moffatt and diphenyl chlorophosphate activation strategies.

One-pot synthesis of functionalized nitrones from nitro compounds

The zinc-mediated reduction of nitroalkanes and nitroarenes in the presence of aldehydes is an efficient method to synthesize a wide range of nitrones. This method is mild enough to accommodate a variety of functional groups. It is particularly useful when the intermediate hydroxylamines are unstable and/or water-soluble. We used it to prepare several aromatic, aliphatic and highly functionalized sugar-derived nitrones.

Synthesis of several sulphated and non-sulphated pentasaccharides, corresponding to the E. coli K5 glycosaminoglycan

The synthesis is described of four pentasaccharides, which are structurally related to the bacterial capsular polysaccharide isolated from E. coli K5 (010/K5/H40), i.e. the so-called K5 antigen.These four synthetic compounds comprise: (i) a pentasaccharide that is structurally identical to the K5 antigen (i.e. compound 16); (ii, iii) two pentasaccharides containing two and three O-sulphated groups respectively on defined positions (i.e. compounds 15a and 15b); (iv) a pentasaccharide that is O-sulphated on all hydroxyl groups (i.e. compound 17).These four K5-antigen-related pentasaccharides were synthesized from the fully protected pentasaccharides 13a and 13b.The preparation of compounds 13a,b was based on coupling of disaccharide 6a with the disaccharide 10a or 10b to give tetrasaccharides 11a,c, respectively, which in turn were coupled to monosaccharide 12.Deblocking of the pentasaccharides 13a,b and conversion into the pentasaccharides 15a and 15b was performed by saponification of the ester functions, O-sulphation, hydrogenalysis and finally selective N-acetylation. compound 16 was obtained from 13a,b by saponification of the ester functions, deblocking of the benzyl and N-protective groups, followed by selective N-acetylation.The persulphated derivative 17 was obtained from 15a by extensive O-sulphation.The structure of the K5-antigen-related pentamers was confirmed by 1H NMR- and 13C NMR-spectroscopical techniques.
