Biological oxidation

In this paper, we present the synthesis of intermediate compounds 2 and 3, which are the key compounds for synthesizing the derivatives of schweinfurthin G using chiral ionic liquid. These compounds are the key blocks to further synthesize schweinfurthin G derivatives for biological activity tests.

The flavanone glycoside naringin, which is abundant in the very immature pomelo peel cultivated in Vietnam, has been demonstrated to have potential use in semisynthesis into other flavonoid compounds, especially apigenin, which exhibits several biological properties and has a greater commercial value. In this study, we carried out an oxidation reaction on flavanone backbone to semisynthesize apigenin with I2 catalyst in some environmentally friendly solvents such as a replacement for the reaction in the pyridine solvent, which is thought to be a non-green solvent.

Ebook "Novel synthetic chemistry of ureas and amides" investigates the chemistry and application of molecules containing urea and amide bonds. These bonds are some of the strongest known and are fundamental to biological processes. The author describes his discovery that sterically hindered ureas undergo solvolysis at room temperature under neutral conditions. This is a remarkable finding, since ureas are inert under these conditions and a general rule of chemistry is that hindered substrates are less reactive.

Ebook "Vanadium: Biochemical and molecular biological approaches" is particularly timely as it exactly coincides with the centennial anniversary of the discovery of vanadium by Professor Henze, in the blood cells of an ascidian (tunicate) collected in Gulf of Naples in 1911. Vanadium, atomic number 23, covers a wide range of oxidation states (from -2 to +5) and has unpaired electrons. Depending on these properties, a wide variety of enzymes and compounds containing vanadium have been found and the biochemical behaviour of vanadium has been investigated extensively.

In ebook "High- and low-valent tris-N-heterocyclic carbene iron complexes: A study of molecular and electronic structure" high valent iron nitride and oxo species have been proposed as key intermediates in many bio-catalytic transformations, but until now these species have proven exceedingly challenging to isolate and study. Iron complexes in high oxidation states can thus serve as models for iron-containing enzymes to help us understand biological systems or aid our development of more efficient industrial catalysts.
