Synthesis of novel di- and trisaccharide mimetics with non-glycosidic amino bridges

Synthesis of novel di- and trisaccharides using enzymatic glycosylation, Dess-Martin oxidation and reductive animation allows rapid access to the target structures. Thus, a novel class of glycomimetics was obtained having nitrogen inserted as bridging atom between two non-anomeric positions. Novel di- and trisaccharide mimetics were designed using N-acetylglucosamine as a basis structure. A third monosaccharide unit was attached via an unnatural sugar-sugar bond without participation of the anomeric center. Their synthesis, proceeding via oxidation, glycosylation and reductive animation, required only a few steps, thus allowing rapid access to the target structures. Generation of the novel pseudo-disaccharide was achieved by Dess-Martin oxidation and a subsequent reductive amination. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

Reactivity of bis(pyridyl)- N -alkylaminato methylpalladium complexes toward ethylene: insights from experiment and theory

A series of novel neutral and cationic methylpalladium complexes bearing N-alkyl-2,2-dipyridylaldiminato ligands were prepared and characterized. In the presence of ethylene, the cationic complexes were active as dimerization catalysts, producing a mixture of 1- and 2-butenes. A Pd-ethyl pi-ethylene species was identified as the catalyst resting state by low-temperature spectroscopic and DFT studies, which provided insights into the effect of both steric and electronic factors on the observed reactivity.

The structural characterisation of compounds 4 and 6, and of the starting compound Co(eta5-C5H5)(PPh3)I2 (1) was done by single-crystal X-ray diffraction studies. DFT calculations (ADF program) were performed in order to understand the orthometallation reaction.

Use of dichlorophthaloyl (DCPhth) group as an amino protecting group in oligosaccharide synthesis

As an alternative to phthaloyl (Phth) group, 4,5-dichlorophthaloyl (DCPhth) group was investigated as an amino protecting group to prove it to be useful for the synthesis of beta-glycosides of 2-acetamido-2-deoxy glucose (GlcNAc). DCPhth was introduced onto the C-2 nitrogen of glucosamine to give 2, which was further transformed into mono- and di- and trisaccharide derivatives which constitute basic structural units of asparagine linked glycoprotein oligosaccharides. DCPhth group proved to have sufficient stability under the standard conditions of protecting group manipulations (e.g. deacetylation, benzylation, benzylidenation), and Lewis acid-, silver salt- and iodonium ion-promoted glycosylation. Removal of DCPhth group was smoothly performed by using ethylenediamine in alcoholic solvent under substantially milder conditions required for deprotection of Phth.

Comprehensive metabolic fingerprinting of Withania somnifera leaf and root extracts

Profiling of metabolites is a rapidly expanding area of research for resolving metabolic pathways. Metabolic fingerprinting in medicinally important plants is critical to establishing the quality of herbal medicines. In the present study, metabolic profiling of crude extracts of leaf and root of Withania somnifera (Ashwagandha), an important medicinal plant of Indian system of medicine (ISM) was carried out using NMR and chromatographic (HPLC and GC-MS) techniques. A total of 62 major and minor primary and secondary metabolites from leaves and 48 from roots were unambiguously identified. Twenty-nine of these were common to the two tissues. These included fatty acids, organic acids, amino acids, sugars and sterol based compounds. Eleven bioactive sterol-lactone molecules were also identified. Twenty-seven of the identified metabolites were quantified. Highly significant qualitative and quantitative differences were noticed between the leaf and root tissues, particularly with respect to the secondary metabolites.
