Hydrogen-Bonding-Regulated Supramolecular Nanostructures and Impact on Multivalent Binding

Herein we describe the H-bonding-regulated nanostructure, thermodynamics, and multivalent binding of two bolaamphiphiles NDI-1 and NDI-2 consisting of a hydrophobic naphthalene diimide connected to a hydrophilic wedge by a H-bonding group and a glucose mo

Synthesis and anti-tumor activity of glycosyl oxadiazoles derivatives

A new series of glycosyl oxadiazoles compounds were synthesized and characterized through 1H NMR, 13C NMR, IR and HRMS. The anti-tumor activities for MDA-MB-231 of all these new compounds were screened in vitro by MTT assay. Due to the modification of gastrodin analogues, the anti-tumor activities of these 1,3,4-oxadiazoles derivatives were greatly improved. Six compounds (6c, 6d, 6i, 6j, 6k and 6l) displayed relatively higher MDA-MB-231 potency with IC50 values (0.89, 0.26, 1.35, 3.60, 0.95 and 1.08 μM) compared with the reference medicine Rosiglitazone (5.23 μM).

Revisit of the phenol O-glycosylation with glycosyl imidates, BF 3·OEt2 is a better catalyst than TMSOTf

With BF3·OEt2 as the catalyst, the glycosylation of phenols with glycosyl trichloroacetimidates (or N-phenyl trifluoroacetimidates) bearing 2-O-participating groups leads to the desired 1,2-trans-O-glycosides in generally excellent yields without formation of the 1,2-cis-anomers. However, with TMSOTf as the catalyst, the outcomes of the corresponding phenol O-glycosylation are highly dependent on the nucleophilicity of the phenols; less nucleophilic is the phenol, higher amounts of the 1,2-cis-O-glycoside together with more side-products are generated. 1,2-Orthoesters have been found to be the major products at a low temperature (a higher temperature. BF 3·OEt2 is an effective catalyst to promote the conversion of 1,2-orthoesters into the corresponding 1,2-trans-O-glycosides. However, the 1,2-orthoesters could be converted into the dioxolenium triflate and glycosyl triflate in the presence of TMSOTf, these intermediates which might be in equilibrium with the glycosyl oxocarbenium related species lead to the final mixture of the α/β-O-glycosides and side-products.

Highly efficient β-glucosylation of the acidic hydroxyl groups, phenol and carboxylic acid, with an peracetylated glucosyl fluoride using a combination of BF3·Et2O and DTBMP as a promoter

A combination of BF3·Et2O and DTBMP was established to be an efficient promoter of β-glucosylation of both phenols and carboxylic acids with a peracetylated glucosyl fluoride (2). This new method achieved remarkably high yields and β

Reliable method for the synthesis of aryl β-D-glucopyranosides, using boron trifluoride-diethyl ether as catalyst

Stereospecific formation of aryl 2,3,4,6-tetra-O-acetyl-β-D-glucopyranosides was achieved by reaction of penta-O-acetyl-β-D-glucose 1 with substituted phenols in the presence of boron trifluoride. Yields of the purified products varied from 52-85%. Benzyl alcohol could also be glucosylated using similar conditions. All products were purified by crystallization from ethanol. The purity and the anomeric configuration of the products were determined by means of 1H and 13C NMR spectroscopy, melting points and optical rotation.

Novel Synthesis of Aryl 2,3,4,6-Tetra-O-acetyl-D-glucopyranosides

The glucosidation of phenols with 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl fluoride in the presence of BF3*OEt2 to give, predominantly, α-anomers has been studied.In the presence of an amine base, 1,1,3,3-tetramethylguanidine, however, enhanced β-selectivity was achieved.The former reaction provides a novel and useful synthesis of aryl 2,3,4,6-tetra-O-acetyl-α-D-glucopyranoside whilst the latter is effective for the glycosidation of relatively hindered phenols.
