Novel building units with bimetallic rings in inorganic/organic hybrid chains and layers

Hydrothermal synthesis has produced three new compounds constructed from novel building units containing vanadium-oxide (or oxyfluoride) subunits linked together via covalently bound cationic copper complexes. Each new compound exhibits novel structural features: [Cu(dipa)][VOF4] (1) incorporates a corner-sharing octahedral vanadium(IV) oxyfluoride chain decorated by copper-(2,2?-dipyridyl amine) complexes which form intra-chain bridges. Within a similar reactant system [Cu(dipa)]2[V6O17] (2) is produced, the structure of which exhibits edge-sharing trigonal bipyramidal vanadium(V) ‘ladder-like’ double chains which are bridged into layers by tetrahedral pyrovanadate dimers together with the copper-(2,2?-dipyridyl amine) complexes. [Cu(py)4]2[V4O12] (3), is a 2-D structure featuring exclusively tetrahedral vanadium(V) in four-membered ring building blocks, linked through octahedral copper-pyridine complexes to form two crystallographically different bimetallic layers.

Glucosamine conjugates bearing N,N,O-donors: Potential imaging agents utilizing the [M(CO)3]+ core (M = Re, Tc)

The design rationale, synthesis and radiolabeling evaluation of four glucosamine conjugated ligands for the [99mTc(CO)3] + core is described. The capability to bind the tricarbonyl core is initially demonstrated using the cold surrogate [Re(CO)3] +. The four compounds are competent chelates in binding [ 99mTc(CO)3]+ as labeling studies show, with yields ranging from 79 to 96% and the resulting complexes showing stability in the presence of competing chelates for 24 h at 37 C. The rhenium complexes were tested for hexokinase-catalysed phosphorylation, and the technetium complexes were tested for GLUT-1 mediated cell uptake – they showed a small amount of uptake but it was not glucose dependent, suggesting that it was not via the GLUT-1 transporters.

Synthesis of orthogonally protected muramic acid building blocks for solid phase peptide synthesis

Muramic acid is found in many peptide natural products containing oligo(poly)saccharide moieties. Taking into consideration that the Fmoc methodology is routinely used for solid-phase peptide synthesis, preparation of orthogonally protected muramic acid building blocks for total solid-phase synthesis of these natural products is of particular practical importance. Herein a simple and efficient synthesis of benzyl 2-amino-4,6-O-benzylidene-3-O-[(R)-1-carboxyethyl]-2-deoxy-N-9-fluorenylmethyloxycarbonyl-alpha-D-glucopyranoside (6) from N-acetylglucosamine (1) is described. Important improvements over previous synthetic approaches to glucopyranosides 2 (benzyl 2-acetamido-2-deoxy-alpha-D-glucopyranoside) and 3 (benzyl 2-acetamido-4,6-O-benzylidene-2-deoxy-alpha-D-glucopyranoside), key building blocks in preparation of 6, include synthesis simplification and efficient isolation and purification. Optically pure (S)-2-chloropropionic acid 7 was prepared and introduced to the positon 3-O of sugar moiety to give compound 4 (benzyl 2-acetamido-4,6-O-benzylidene-3-O-[(R)-1-carboxyethyl]-2-deoxy-alpha-D-glucopyranoside) with the (R)-configuration of the lactyl side-chain in excellent overall yield and optical purity. Deacetylation of amino group gave compound 5 (benzyl 2-amino-4,6-O-benzylidene-3-O-[(R)-1-carboxyethyl]-2-deoxy-alpha- D-glucopyranoside) suitable for incorporation of the Fmoc protecting group to give protected muramic acid derivative 6, a useful building block in peptide synthesis.

Formic acid-mediated liquefaction of chitin

We report pure formic acid-mediated liquefaction of chitin for the first time. Formic acid exhibited a remarkable ability in the functionalization and depolymerization of ball-milled chitin as well as proto-chitin in raw shrimp shells. Up to 60% combined yield of a series of structurally identified monomeric products was obtained after reaction at 100 C for 12 h. The product stream could also converge to a single compound, 5-(formyloxymethyl)furfural (FMF), in 35% yield after a longer reaction time. The product evolution was monitored by electrospray ionization mass spectrometry (ESI-MS), and the key finding is that the liquefaction involves several major chemical events in the following sequence: (1) the process starts with partial formylation of the hydroxyl groups in chitin side chains generating soluble polymeric derivatives; (2) formic acid catalyzes polymer chain breakage in a non-conventional, non-hydrolytic pathway forming dehydrated monomers and oligomers; (3) as formylation continues, water accumulates in the system, which induces more monomer and oligomer generation via hydrolysis, and the formation of rehydrated products. As such, water is constantly generated via formylation and subsequently consumed in hydrolysis and rehydration, making the process a self-sustained one.

A versatile approach towards multivalent saccharide displays on magnetic nanoparticles and phospholipid vesicles

A simple synthetic route has been devised for the production of coating agents that can give multivalent displays of saccharides on the surface of magnetite nanoparticles and phospholipid vesicles. A versatile and potentially high-throughput condensation reaction allowed the rapid synthesis of a variety of glycosylhydrazide conjugates with lipid, resorcinol or catechol termini, each in good yield and high anomeric purity. The hydrolytic stability of these adducts was assessed in D2O at different pD values using 1H-NMR spectroscopy, whilst quartz crystal microbalance with dissipation monitoring (QCM-D) confirmed that the saccharide functionality on bilayers and on nanoparticles was still available to lectins. These multivalent saccharide displays promoted nanoparticle interactions with cells, for example N-acetylglucosamine-coated nanoparticles interacted much more effectively with 3T3 fibroblasts than uncoated nanoparticles with these cells. Despite potential sensitivity to oxidation, catechol coatings on magnetite nanoparticles were found to be more stable and generate better nanoparticle interactions with fibroblasts than resorcinol coatings.

Carbon-13 NMR Spectra of Saturated Heterocycles. XI – Tetrahydropyrans (Oxanes)

The 13C NMR spectra of 62 oxanes (tetrahydropyrans) with and without methyl substituents at various ring positions, some of them bearing in addition (or instead) ethyl, vinyl, ethynyl, carbomethoxy and methylol substituents at C-2, have been recorded, and the 294 resulting chemical shifts have been correlated by multiple linear regression analysis.Axial and equatorial alpha-, beta-, gamma-, delta-, gem- and vic-parameters for shifts caused by methyl groups at all ring positions, and similar parameters for Et, -CH=CH2, -C<*>CH, CO2Me and CH2OH groups at C-2, are reported.Standard deviations of the parameters are, in most cases, within 0.3 ppm and the agreement of calculated and experimental shifts is excellent.This is probably the largest parameter set of this type extant. 13C NMR spectra of a number of additional substituted tetrahydropyrans, and of 3,6-dihydro-2H-pyrans and 3,4-dihydro-2H-pyrans, are tabulated and discussed.
