[2-13C]-Quercetin-4′-O-beta-glucoside was synthesised in four steps and 28% yield from barium [13C]-carbonate. This short route will be applicable to the synthesis of radiolabelled quercetin-4′-O-beta-D-glucoside from barium [14C]-carbonate. The most important feature is control of the regiochemistry and stereochemistry of glycosylation before introduction of the isotopic label. The synthesis also uses only benzyl protecting groups allowing global deprotection in the last step. (C) 2000 Elsevier Science Ltd.

Catalytic amounts of Sm(OTf)3 activate armed glycosyl trichloroacetimidates under very mild conditions. This reagent proved effective in promoting the glucosylation of saccharidic acceptors 2, 3, 4, and 5, possessing primary or secondary hydroxyls, with the model donor 1. The stereoselectivity of these glycosidations can be controlled by a suitable choice of solvent. (C) 2000 Elsevier Science Ltd.

A new approach to deliver dopamine into the central nervous system, based on the use of D-glucose as transportable agent, has been studied. Glycosyl dopamine derivatives bearing the sugar moiety linked to either the amino group or the catechol ring of dopamine through amide, ester or glycosidic bonds were synthesised as potential antiparkinsonian agents. Studies on the binding to dopamine D2 receptor, in vitro stability, and locomotive effect in mice of the synthetic glycoconjugates are reported. Copyright (C) 2000 Elsevier Science Ltd.

Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals. However, they have proven to be challenging because of the mutual inactivation of both catalysts. 74808-09-6, Name is (2R,3R,4S,5R,6R)-3,4,5-Tris(benzyloxy)-6-((benzyloxy)methyl)tetrahydro-2H-pyran-2-yl 2,2,2-trichloroacetimidate, molecular formula is C36H36Cl3NO6.

Reaction of O-benzyl-protected alpha-glycopyranosyl trichloroacetimidates 1 and the xylo analogues 7 with silyl enol ethers or allyltrimethylsilane as C-nucleophiles yields with zink chloride as catalyst mainly or exclusively alpha-C-glycosides (5a-alpha to 5h-alpha, 8b, c-alpha, 16-alpha, 18-alpha).For the reactions with trimethylsilyl cyanide to form alpha-C-glycosyl cyanides (10-alpha, 14-alpha, 15-alpha), trimethylsilyl trifluoromethanesulfonate was used as catalyst.Silyl enol ethers reacted with the 2-O-acetyl group of the O-acetylated alpha-glycosyl trichloroacetimidate 2 under formation of 1,3-dicarbonyl derivatives (9a, b). – Reaction of the alpha-glucopyranosylmethyl phenyl ketone 5a-alpha with Bredereck reagent and subsequently with hydrazine, acetamidine, or guanidine gives via intermediate anomerisation preferentially beta-C-nucleosides (21-beta, 24-beta, 25-beta).However, alpha-homo-C-nucleosides (26-alpha, 30-alpha to 32-alpha, 35-alpha, 38-alpha) are obtained from the corresponding reactions with alpha-glycopyranosylmethyl alkyl ketones 5c, d, e-alpha and 8c-alpha.For structural analysis these compounds were deprotected and acetylated.

As expected, the reactive acetyl-protected O-(alpha-D-glucopyranosyl) trichloroacetimidate 3 reacts with S-nucleophiles and trifluoroborane-ether as catalyst to yield exclusively 1-thio-beta-D-glucopyranosides with inversion of the configuration.The corresponding benzyl-protected alpha-trichloroacetimidate 4 affords with retention of the configuration alkyl 1-thio-alpha-D-glucopyranosides.The importance of alkyl 1-thio-beta-D-galactopyranosides in enzyme induction was reason to apply this convenient and efficient glycosyl-transfer reaction to the synthesis of isopropyl 1-thio-beta-D-galactopyranoside (12a) and the sodium salt of 1-thio-beta-D-galactopyranose (12b), respectively.

Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition. 74808-09-6, Name is (2R,3R,4S,5R,6R)-3,4,5-Tris(benzyloxy)-6-((benzyloxy)methyl)tetrahydro-2H-pyran-2-yl 2,2,2-trichloroacetimidate, molecular formula is C36H36Cl3NO6.

Gold(III) chloride as catalyst for O-glycosyl trichloroacetimidate activation revealed low affinity to the glycosyl donor but high affinity to the hydroxy group of the acceptor alcohol moiety, thus leading to catalyst-acceptor adduct formation. Charge separation in this adduct, increasing the proton acidity and the oxygen nucleophilicity, permits donor activation and concomitant acceptor transfer in a hydrogen-bond mediated SN2-type transition state. Hence, the sequential binding between acceptor and catalyst and then with the glycosyl donor enables self-organization of an ordered transition-state. This way, with various acceptors, even at temperatures below -60 C, fast and high yielding glycosidations in high anomeric selectivities were recorded, showing the power of this gold(III) chloride acid-base catalysis. Alternative reaction courses via hydrogen chloride or HAuCl4 activation or intermediate generation of glycosyl chloride as the real donor could be excluded. With partially O-protected acceptors, prone to bidentate ligation to gold(III) chloride, particularly high reactivities and anomeric selectivities were observed. Gold(I) chloride follows the same catalyst-acceptor adduct driven acid-base catalysis reaction course.

The rearrangement of allylic trichloroacetimidates is a well-known transformation, but the corresponding rearrangement of benzylic trichloroacetimidates has not been explored as a method for the synthesis of benzylic amines. Conditions that provide the trichloroacetamide product from a benzylic trichloroacetimidate in high yield have been developed. Methods were also investigated to transform the trichloroacetamide product directly into the corresponding amine, carbamate, and urea. A cationic mechanism for the rearrangement is implicated by the available data.
