An iron(III) phosphonate cluster containing a nonanuclear ring This paper reports the first example of cyclic ferric clusters with an odd number of iron atoms capped by phosphonate ligands namely [Fe9(μ-OH)7(μ-O)2(O3PC6H9)8(py)12] The magnetic studies support a S = 1/2 ground state with an exchange coupling constant of about J ≈-30 K Cyclic iron cages are attractive not only

Cyclic carbonate groups are currently gaining increasing attention both from academic and industrial communities Indeed these functions allow a better control in terms of spontaneous crosslinking reactions than other reactive groups and could also come from renewable resources such as glycerine or CO2 Although many papers report the use of cyclic carbonates for synthesis of linear

Protecting phosphonates as prodrugs has shown promise in drug delivery Thus a variety of structures and cleavage/activation mechanisms exist enabling release of the active compound This review describes the structural diversity of these pro-moieties relevant cleavage mechanisms and recent advances in the design of phosphonate prodrugs

Polyphosphates can have linear or cyclic ring structures In water treatment general orthophosphate and polyphosphate are used They may be used either alone or mixed together to stabilize water quality and minimize corrosion in drinking water systems Polyphosphate-type chemicals react with soluble metals (Fe Mn Ca Mg etc ) by sequestering (binding) the metals to maintain their solubility

phosphate and phosphonate ly to form ATP but to promote the binding of : phosphate and mostly the release of tightly bound ATP DP and sulfate whereas its two products are : phosphate and adenylyl sulfate ose 1-phosphate and two products glycerone : phosphate and formaldehyde and taurine whereas its 3 products are ADP phosphate and taurine ce this enzyme has one substrate

This paper describes the first diastereoselective synthesis of cyclic α‐aminophosphonic and α‐amino phosphonic acids from glycyl Acid hydrolysis of the phosphonate and phosphinate functionalities with simultaneous cleavage of the tert ‐butyl carbamate protecting group led to the target compounds The high diastereoselectivity in the nucleophilic addition of trivalent phosphorus to

Analogues of l-fucose N-acetyl-d-glucosamine N-acetyl-d-mannosamine and N-acetyl neuraminic acid in which the anomeric carbon atom was replaced by a phosphonyl group (phostones or cyclic phosphonates) were synthesized by stereocontrolled methods relying on the Abramov reaction

The present invention relates to a class of new phosphonate compounds and possible applications of such phosphonate compounds Compounds according to the present invention actually combine two groups namely group reactive phosphonate and the grouping class specific reagents as more defined below New connections can be considered highly suitable for use in many industrial applications

This building block has N-terminal cutinase and C-terminal SnapTag domains that react irreversibly with p-nitrophenyl phosphonate (pNPP) and benzylguanine (BG) groups respectively We use a bis-BG and a BG-pNPP linker to join these fusion proteins into linear structures that can then react with a bis-pNPP linker that joins the ends into a cyclic product The last step can occur

Diphenyl (2 3-dihydro-2-thioxo-3-benzoxazolyl)phosphonate (1) prepared from 2-benzoxazolethiol and diphenyl phosphorochloridate was proved to be a very useful condensing agent A variety of amides esters and dipeptides were obtained in excellent yields Furthermore this reagent was successfully applied to the synthesis of β-lactams from β-amino acids
