Synthesis of Cage-Shaped Aluminum Aryloxides: Efficient Lewis Acid Catalyst for Stereoselective Glycosylation Driven by Flexible Shift of Four- To Five-Coordination

Monomeric cage-shaped aluminum aryl oxides 1Al were synthesized using tripodal triphenolic ligands. The Lewis acidity and catalytic activity of the obtained 1Al·py were investigated. The Lewis acidity of 1Al·py originates from the flexible change in the coordination number of the aluminum center, allowing the catalytic O-glycosylation to occur with a high efficiency and an unusual stereoselectivity.

Efficient methods for glycosidations with glycals – A key intermediate for the synthesis of mucin core 1-type O-glycan

The use of glycals as acceptors in glycosylation reactions is hampered by their sensitivity to acids. We report here on the successful use of mild Lewis acid [Sn(OTf)2] as catalyst for the glycosylation with O-glycosyl trichloroacetimidates and on the development of this method to construct a key intermediate for the synthesis of mucin type O-glycans. To this end, chemoselective nitration of O-glycosylated glycals, stereoselective threonine addition, and reduction of the nitro group to the amino group by an efficient procedure avoiding the use of an expensive catalyst was performed.

Glycosylidene Carbenes, Part 10. Regioselective Glycosidation of 4,6-O-Benzylidene-D-altropyranosides

Glycosidation by the diazirine 1, the trichloroacetimidate 4, and the bromide 5 of the altro-diol 2, possessing an intramolecular H-bond (HO-C(3) to O-C(1)) in solution, but not in the solid state, proceeds with high and complementary regioselectivity.From 2 and 1, one obtains mostly the 1,2-linked disaccharides 10 and 11 (beta-D > alpha-D), together with the 1,3-linked isomers 12 and 13 (alpha-D > beta-D; 1,2-/1,3-linked products ca.9:1), the demethylated 1,3-linked disaccharides 24-27, the trisaccharides 19-22, the lactone azines 23, and the hydroxyglucal 18, while 2 reacted with 4 or 5 to yield mostly the 1,3-linked disaccharides (1,2-/1,3-linked products ca. 1:9).The disaccharides were additionally characterized as acetates (-> 14-17, 28-31).Yields and stereoselectivity depended upon the donor, stoichiometry, solvent, temperature, and concentration.Glycosidation of the 1,3-linked disaccharides with 1 yielded the trisaccharides 19-22.Reaction of the beta-D-altro-diol 3 with 1 gave the 1,2- and 1,3-linked disaccharides 32/33 and 34/35 in a 1:1 ratio, characterized as the acetates 36-39, while glycosidation with 5 according to Lemieux proceeded regioselectively (1,2-/1,3-linked products 91:9).The monotosylates 6 and 7 reacted with 1 to yield the anomeric pairs 40/41, and 42/43 of the tosylated disaccharides; the oxiranes 44 and 45 were not observed.

CARDIAC GLYCOSIDES: 5. STEREOSELECTIVE SYNTHESES OF DIGITOXIGENIN alpha-D, beta-D, alpha-L AND beta-L-GLUCOSIDES

As part of a continuing study of cardiac glycosides, stereoselective syntheses of the four possible glucosides of digitoxigenin were developed via the thermodynamically produced tetra-O-benzyl-D- and L-glucosyl alpha-trichloroacetaimidates 2alpha and 11alpha, and the kinetically produced beta-trichloroacetaimidates 2beta and 11beta.A 58percent:19percent isolated yield ratio of alpha-D and beta-D benzyl protected glycosides 6 and 3 could be obtained in 30 minutes reaction at -10 deg.Halide ion catalysis with a 2:1 excess of tetra-O-benzyl-alpha-D-glucopyranosyl bromide for 14 days in methylene chloride at room temperature gave a 39percent:11percent ratio of 6 and 3, along with 43percent of recovered digitoxigenin.Debenzylation of the D-glucosides required milder conditions (20percent Pd/C, atmospheric pressure, 45 min – 1 hr) than the L-glucosides (40percent Pd/C, 2 hr) but yields were typically 80percent for both groups.

Three oxidative metabolites of indole-3-acetic acid from Arabidopsis thaliana

Three metabolites of indole-3-acetic acid (IAA), N-(6-hydroxyindol-3-ylacetyl)-phenylalanine (6-OH-IAA-Phe), N-(6-hydroxyindol-3-ylacetyl)-valine (6-OH-IAA-Val), and 1-O-(2-oxoindol-3-ylacetyl)-beta-d-glucopyranose (OxIAA-Glc), were found by a liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS)-based search for oxidative IAA metabolites during the vegetative growth of Arabidopsis. Their structures were confirmed by making a comparison of chromatographic characteristics and mass spectra between naturally occurring compounds and synthetic standards. An incorporation study using deuterium-labeled compounds showed that 6-OH-IAA-Phe and 6-OH-IAA-Val were biosynthesized from IAA-Phe and IAA-Val, respectively, which strongly suggested the formation of these amino acid conjugates of IAA in plants. Both 6-OH-IAA-Phe and 6-OH-IAA-Val were inactive as auxins, as indicated by no significant root growth inhibition in Arabidopsis. Quantitative analysis demonstrated that OxIAA-Glc was present in the largest amount among the metabolites of IAA in Arabidopsis, suggesting that the conversion into OxIAA-Glc represents the main metabolic process regarding IAA in Arabidopsis.

Dye-sensitized photooxygenation of 2,5-Bis(glycosyl)furans

The dye-sensitized photooxygenation of 2,5-bis(glycosyl)furans followed by warming up to r.t. provides 1,1′- linked disaccharides separated by a functionalized spacer. Asymmetrical disubstituted glycosyl furans give the corresponding Bayer-Villiger type-rearranged products in a molar ratio depending on the sugars and the protecting groups. The migratory aptitudes have been rationalized by both theoretical calculations and experimental data. The 1,1′- disaccharides obtained are new sugar derivatives structurally related to some mimetics of Sialyl Lewis X.

Glycosylidene Carbenes, Part 9: Regioselective Glycosidation of Diols and Triols: Intra- and Intermolecular Hydrogen Bonds

Glycosidation of the myo-inositol derivatives 2 and 3 by the diazirine 1 yields 90percent of a diastereoisomer pair of beta-D-glycosides in a 1:1 ratio, i.e. 5/6 and 7/8, respectively (Scheme 1).The crystal structure of 3 shows a strong intramolecular H-bond, which persists in solution, as indicated by FT-IR and 1H-NMR spectra.Yields and diastereoselectivity are lower for the glycosidation of 24 by 1 (Scheme 3).The resulting 1,2- and 1,4-linked disaccharides 25-28 were isolated as their acetates 29-32.The previously determined crystal structure of 24 shows no intramolecular H-bonds.The yield of the glycosidation of 24, but not of 3, depends upon the concentration, indicating that activation of 24 by intermolecular H-bonds is required.Glycosidation of 2 and 3 with the trichloroacetimidate 14 gave mixtures of four (5, 6, 15, and 16), and six (7, 8, and 17-20) disaccharides, respectively (Scheme 2).

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.
