Highly selective formation of beta-glycosides of N-acetylglucosamine using catalytic iron(III) Triflate

Efficient and highly selective glycosylation reactions of peracetylated beta-D-N-acetylglucosamine are described using catalytic iron(III) triflate and 2,4,6-tri-tert-butylpyrimidine (TTBP) under microwave conditions. We have demonstrated that the formation of beta-(1?6) and beta-(1?3) linked disaccharides are obtained in high yields in the presence ofvarious protecting groups.

Synthesis, Characterization, X-Ray Crystallography, and Antileishmanial Activities of N-Linked and O-Linked Glycopyranosides

Novel N-linked 5a-e and O-linked glycopyranosides 7a-e were synthesized in high yield from commercially available L-tartaric acid containing two asymmetric centers and C2 axis of symmetry. The compound L-tartaric acid was completely protected and then partially hydrolyzed to get the monoester, which upon treatment with different amino and hydroxyl derivatives of glycopyranoses gave the desired amides and esters. The synthesized derivatives were purified by chromatography and characterized by spectroanalytical techniques. The structure of compound 7c in the series was supported by X-ray analysis. Leishmanicidal activities of compounds 5a-e and 7a-e were investigated which showed moderate to good activities.

Ring-Centered Heterocyclic Cations and the Direct Heteroarylation of Aromatic and Heterocyclic Compounds

(matrix presented) The protonation of heterocyclic diazotates (attachment adjacent to a nitrogen atom) yields ring-centered heterocyclic carbocations that are highly reactive. The carbocations were found to alkylate aromatic and heterocyclic compounds, such as benzene, N-methylpyrrole, and 2-aminopyridine, in reactions that are synthetically useful. This carbocation involvement may serve as a paradigm for the cross-linking of DNA by nitrous acid and the anticancer activity of heterocyclic diazotates.

First O-glycosylation of hydroxamic acids

(Chemical Equation Presented) The first O-glycosylation of hydroxamic acids is reported. This process involves the use of glycosyl N-phenyl trifluoroacetimidates as glycosyl donors in the presence TMSOTf and 4 A molecular sieves in dichloromethane. Under such conditions, a wide range of new glycosyl donors including glucosyl, galactosyl, mannosyl, glucuronyl, and ribosyl hydroxamates were prepared in good to high yields. This procedure appears to be an advantageous alternative for the synthesis of glycosyl hydroxamates of biological interest.

A new dinuclear biphenylene bridged copper(II) complex: DNA cleavage under hydrolytic conditions

The dinucleating ligand, tpbpd (tetrapyridyl biphenylenediamine) forms a dicopper complex with practically no electronic coupling between the two copper (II) centres. The EPR spectrum of the complex is consistent with coordination of each copper ion to two nitrogens of the binuclear ligand. Cyclic voltammogram of the complex also reveals that the two copper (II) centres have identical ligating environment. This dimeric copper (II) complex is found to be a very efficient catalyst for the cleavage of plasmid DNA in the absence of any added cofactor. The amount of conversion of supercoiled form (Form I) of plasmid to the open circular form (Form II) depends on the concentration of the complex as well as the duration of incubation of the complex with DNA. The maximum rate of conversion of the supercoiled form to the nicked circular form at pH 7.5 in the presence of 150 muM of the complex is found to be 1.8 × 10-3 s-1.

Effective protection of the N-sulfate of glucosamine derivatives with the 2,2,2-trichloroethyl group

The 2,2,2-trichloroethyl (TCE) group was utilized as the first protecting group for N-sulfates (chlorosulfuric acid TCE ester, Et3N, DMAP, DMF). Glycosylation with 3,4,6-tri-O-acetyl-N-trichloroethylsulfuryl-alpha-d-glucosaminosyl trichloroacetimidate provided the corresponding beta-glucosaminosides stereoselectively and in excellent yields. The TCE protection stayed stable under a variety of conditions for the manipulation of other protecting groups, and was readily removable with zinc in the presence of ammonium chloride in methanol.

A divergent synthesis of 2-acyl derivatives of PUGNAc yields selective inhibitors of O-GlcNAcase

A divergent route facilitating the rapid synthesis of a series of O-(2-acetamido-2-deoxy-d-glucopyranosylidene)amino N-phenylcarbamate (PUGNAc)-based inhibitors, bearing different N-acyl groups has been developed. All compounds of this series are inhibitors of both human O-GlcNAcase and human beta-hexosaminidase, yet some effectively exploit differences between the active site architectures of these two human enzymes which render them selective for O-GlcNAcase. Such inhibitors may be valuable tools in dissecting the role of the O-GlcNAc post-translational modification at the cellular and organismal level since these compounds may have different pharmacokinetic properties when compared to other inhibitors of beta-N-acetyl-glucosaminidases.
