A sequential one-pot per-O-acetylation-S-/O-glycosidation of native mono and disaccharides under solvent free conditions using 0.5 mole% of Mg(OTf)2 as a non-hygroscopic, recyclable catalyst is reported. Regioselective 4,6-O-arylidenation of glycosides and thioglycosides with benzaldehyde or p-methoxybenzaldehyde dimethyl acetal is catalyzed by 10 mole% of Mg(OTf)2 to produce the corresponding 4,6-O-arylidenated product in high yields. Mg(OTf)2 can also mediate sequential one-pot benzylidenation-acetylation of mono and disaccharide based glycosides and thioglycosides in high yield.

In the present study, Lactobacillus plantarum glycolipid (GL1) molecule in beta-configuration and its fatty acid analogues were synthesized using trichloroacetimidate methodology. The beta-configuration of the GL1 molecule was unambiguously assigned by NMR studies using 2D-ROESY (NOE) and J-coupling analysis. Dihydrosterculic acid was synthesized using Furukawa’s reagent and the selective esterification of dihydrosterculic acid at C-3 position of glycerol was achieved with EDC-HCl at 0 C. In vitro cytotoxicity of the GL1 molecule and its fatty acid analogues was evaluated against DU145, A549, SKOV3 and MCF7 cell lines. Among all the synthesized molecules, the GL1 molecule and compound 7d showed moderate activity, while the compound 7b showed promising activity against all the tested cell lines with IC50 values of 20.1, 18.2, 19.1 and 17.6 I1/4M, respectively. In addition, all tested compounds showed poor cytotoxicity against normal HUVEC cells. The MCF7 cells when treated with compound 7b showed lower bromodeoxyuridine incorporation levels as compared to untreated cells, suggesting that the compound 7b was highly effective and inhibited the cell proliferation. In addition, the compounds showed significant increase in caspases 3 and 9 levels by inducing apoptosis in MCF 7 cells.

Reduction of ketone 13, formed by acidic hydrolysis of silyl enol ether 10, with sodium cyanoborohydride in acetic acid gives an 83: 17 mixture of the gamma- and delta-lactone 14 and 15. gamma-Lactone 14 is transformed into the aminomonocarba-disaccharide, 4-acetamido-2,4-dideoxy-3-O-(beta-D-glucopyranosyl)-5a-carba-beta-L-lyxo-hex opyranose 7, using a five-step procedure involving the Curtius rearrangement of acyl azide 16. A similar sequence using gamma-lactone 21, prepared from ketone 12, gives the protected aminomonocarbadisaccharide, 4-acetamido-1,6-di-O-acetyl-2,4-dideoxy-3-O-(2?,3?,4?,6? -tetra-O-acetyl-beta-D-glucopyranosyl)-5a-carba- beta-D-lyxo-hexopyranose 8.

Acetylation under acidic conditions followed by reduction with sodium cyanoborohydride in acetic acid gives a 75: 25 mixture of the gamma- and delta-lactone 28 and 29. Using a sequence similar to that employed for the preparation of compounds 7 and 8, gamma-lactone 28 is converted into the fully substituted aminomonocarba-disaccharide, 4-acetamido-1,2,6-tri-O-acetyl-4-deoxy-3-O-(2?,3?,4?,6?- tetra-O-acetyl-beta-D-glucopyranosyl)-5a-carba-beta-L-galactopyranose 9.

Trifluoromethylzinc bromide was used to prepare the corresponding glycosyl fluorides from the peracetylated alpha-pyranosyl bromides of D-glucose 1, D-galactose 3, D-mannose 5, D-lyxose 7, and L-rhamnose 9, respectively, in good yields. D-Glucopyranosyl bromide 1 and the D-galactopyranosyl bromide 3, exclusively delivered the corresponding beta-D-glycosyl fluorides 2beta and 4beta. The other bromides 5, 7 and 9 formed mixtures of anomeric fluorides (6alpha/6beta, 8alpha/8beta, 10alpha/10beta). Similarily, the anomeric OH-groups of the D-glycopyranoses 11, 12, 13, 15, 17 could be substituted by fluoride using trifluoromethylzinc bromide/titanium tetrafluoride. In all cases mixtures of anomeric fluorides 2alpha/2beta, 6alpha/6beta, 14alpha/14beta, 16alpha/16beta, and 18alpha/18beta were obtained.

Selective deacetylation reactions of the peracetylated reducing disaccharides (1), (5), (9), (15), beta-D-glucopyranose (17) and 2-acetamido-2-deoxy-beta-D-glucopyranose (19), with 1-2 equiv. of hydrazine hydrate in acetonitrile, gave predominantly the corresponding heptaacetates (2), (6), (10), (16), the tetraacetate (18) and the triacetate (20), with the free hydroxy group at C1. Reaction of (1) with 1-2 equiv. of hydrassine hydrate in N,N-dimethylformamide also afforded the heptaacetate (2), but in lower yield. When reactions of (1), (5) and (9) were performed with 2-5 equiv. of hydrazine hydrate, deacetylation also occurred at other positions to afford the corresponding hexaacetates (3), (7), (11) and (12), with hydroxy groups at C 1,2 or C 1,3, and the pentaacetates (4), (8) and (13), with hydroxy groups at C 1,2,3. Maltose octaacetate (9). in addition, yielded the tetraacetate (14) in which the free hydroxy groups were located at C1,2,2?,3. Compound (15) on treatment with 2-5 equiv. of hydrazine hydrate afforded an intractable mixture. The reaction of methyl 2,3,4,6-tetra-O-acetyl-alpha-D-glucopyranoside (21) with 2-5 equiv. of hydrazine hydrate gave the 3,4,6-triacetate (22), a mixture of the 2,6- and the 3,6-diacetates (23) and (24), respectively, the 4,6-diacetate (25), and the 6-acetate (26).

A catalytic method is developed for the diastereoselective acylation of the anomeric hydroxyl group in diverse carbohydrates to form either alpha- or beta-anomeric esters. While exclusive formation of the beta-isomer was observed in most sugar substrates with one enantiomer of the chiral catalyst, moderate to high alpha-selectivity was obtained by using the other enantiomer of the chiral catalyst. The resulting alpha- and beta-anomeric esters have very different reactivity toward a reduction reaction.
