Organoselenium Chemistry in Stereoselective Reactions
Angewandte Chemie - International Edition, 2000Selenium-based methods have developed rapidly over the past few years asnd organoselenium chemistry has become a very useful tool in the hands of synthetic chemists. The different reactivity of selenium-containing compounds in contrast to the sulfur analogues has led to versatile and new synthetic methods in organic chemistry.

Organoselenium Accelerated Bromolactonization Reaction
The Journal of Organic Chemistry, 2019A highly efficient and regioselective bromolactonization protocol is reported. The quantitative formation of synthetically versatile bromolactones occurs in the presence of only 0.1 mol % of an organoselenium compound, coined DECAD herein, within 90 min. DECAD is conveniently prepared on multigram scale from cheap racemic camphor.

Organoselenium ligands in catalysis
Dalton Transactions, 2012Organoselenium ligands are building blocks of several transition metal complexes which catalyze various organic reactions efficiently in solution. In this review the survey of developments pertaining to the designing of such complexes (along with their Se-ligands), and their uses as catalysts for various organic reactions has been presented with ...

Organoselenium compounds as fluorescent probes
Coordination Chemistry Reviews, 2015Abstract Fluoroprobes are compounds which detect analytes (neutral molecules and ions) by simple, inexpensive, and fast fluorimetric responses. In this review, we provide insights into the development of new organoselenium compounds as fluoroprobes for detecting various analytes. These organoselenium fluoroprobes are capable of metal cation and anion

Organoselenium Compounds in Cancer Chemoprevention
Mini-Reviews in Medicinal Chemistry, 2008Selenium is an important trace element involved in different physiological functions of human body. Knowledge of selenium in biology of cancer has increased at rapid rate especially during last two decades. Basic research and clinical studies involving animal models and more recently studies in human strongly support the protective role of selenium ...

Organoselenium Compounds in Medicinal Chemistry
ChemMedChemAbstractThe chemical and biological interest in this element and the molecules bearing selenium has been exponentially growing over the years. Selenium, formerly designated as a toxin, becomes a vital trace element for life that appears as selenocysteine and its dimeric form, selenocystine, in the active sites of selenoproteins, which catalyze a wide ...

Selenazolidines as Novel Organoselenium Delivery Agents
Bioorganic & Medicinal Chemistry Letters, 2001Two new classes of selenazolidine-4(R)-carboxylic acids (2-oxo and 2-methyl-SCAs) were synthesized and characterized. Both were designed as latent forms of selenocysteine, intended to provide a chemically superior delivery form for selenium. The prodrugs may be clinically useful when selenium supplementation at supranutritional levels is indicated ...

Chemoprevention of cancer by organoselenium compounds
Journal of Cellular Biochemistry, 1995A major research goal of our laboratories is the development of new organoselenium cancer chemopreventive agents with less toxicity compared to some of the historical selenium compounds, such as sodium selenite. Ideally, such agents would be employed to inhibit tumor development in different organs caused by a variety of chemical carcinogens ...
