Synthesis of benzaldehyde-functionalized LewisX trisaccharide analogs for glyco-SAM formation

LewisX (Lex) antigen based carbohydrate-carbohydrate interactions are mediated by complexation of metal ions. Although theoretical studies about the influence of participating hydroxyl groups in the Le x trisaccharide head group (Galbeta(1-4)[Fucalpha(1-3)]GlcNAc) could gave same rudimental information about the basic mechanism behind this interaction, a little is known about orientation and configuration of the hydroxyl groups required for the specific interaction mediated by Ca 2+ complexation. Therefore, there is a need of non-natural derivatives to provide detailed information about the requirements for hydroxyl group arrangement in Lex head group surface plasmon resonance and gold nanoparticle techniques have shown to be powerful tools to investigate carbohydrate-carbohydrate interactions. Benzaldehyde-functionalized glycans can be used for attachment to both gold nanoparticles and surface plasmon resonance sensor surfaces. Therefore, seven benzaldehyde equipped Lex analogs including the natural trisaccharide were synthesized utilizing convergent approach. The derivatives were applied in ongoing carbohydrate-carbohydrate interaction studies by surface plasmon resonance experiments to prove theoretical postulate about the structural requirements of hydroxyl group arrangements in Lex trisaccharides.

Synthesis, characterization, reactivity and structure of some mono and binuclear (eta6-p-cymene)ruthenium(II) complexes

Reactions of [{Ru(eta6-C10H14)Cl2}2] (eta6-C10H14=p-cymene H3C-C6H4-CH(CH3)2) with 4-cyanopyridine (referred hereafler as CNPy) in 1:1 and 1:2 molar ratios in dichloromethane yields the binuclear complex [{Ru(eta6-C10H14)Cl2} 2(mu-CNPy)] and the mononuclear complex [Ru(eta6-C10H14)Cl2(CNPy)]. The latter complex further reacts with [{Ru(eta6-C6Me6)Cl2}2] and [Ru(eta5-C5H5)(PPh3) 2Cl] to give 4-cyanopyridine bridged complexes [Cl2(eta6-C10H 14)Ru(mu-CNPy)Ru(mu6-C6Me 6)Cl2] and [Cl2(eta6-C10H 14)Ru(mu-CNPy)Ru(eta5-C5H 5)(PPh3)2]+.

The reaction products have been characterized by microanalyses and spectroscopic studies (IR, 1H-, 13C-, 31P-NMR).

Design and stereoselective preparation of a new class of chiral olefin metathesis catalysts and application to enantioselective synthesis of quebrachamine: catalyst development inspired by natural product synthesis

A total synthesis of the Aspidosperma alkaloid quebrachamine in racemic form is first described. A key catalytic ring-closing metathesis of an achiral triene is used to establish the all-carbon quaternary stereogeniccenter and the tetracyclic structure of the natural product; the cataly tic transformation proceeds with reasonable efficiency through the use of existing achiral Ru or Mo catalysts. Ru- or Mo-based chiral olefin metathesis catalysts have proven to be inefficient and entirely nonselective in cases where the desired product is observed. In the present study, the synthesis route thus serves as a platform for the discovery of new olefin metathesis catalysts that allow for efficient completion of an enantioselective synthesis of quebrachamine. Accordingly, on the basis of mechanistic principles, stereogenic-at-Mo complexes bearing only monodentate ligands have been designed. The new catalysts provide significantly higher levels of activity than observed with the previously reported Ru-or Mo-based complexes. Enantiomerically enriched chiral alkylidenes are generated through diastereoselective reactions involving achiral Mo-bas ed bispyrrolides and enantiomerically pure silyl-protected binaphthols. Such chiral catalysts initiate the key enantioselective ring-closing metathesis step in the total synthesis of quebrachamine efficiently (1 mol percent loading, 22 C, 1h, >98percent conversion, 84percent yield) and with high selectivity (98:2 er, 96percent ee).

Any molecule functionalized with two or more acrylate groups and one terminal olefin can serve as an ABn monomer when exposed to animidazolinylidene-based ruthenium olefin metathesis catalyst, due to the cross metathesis selectivity of this catalyst. For the polymers obtained by this method, both 1H NMR spectroscopy and triple detector size exclusion chromatography conclusively indicate a branched architecture. Copyright
