Ebselen is the leader of selenorganic compounds, and starting from its identification as
mimetic of the key antioxidant enzyme glutathione peroxidase, several papers have …

Background: The chemistry of organoselenium reagents provides an asset for organic
synthesis. The versatility of these reagents as electrophiles and nucleophiles makes them …

Selenium is an essential trace element in living organisms, and is present in selenoenzymes
with antioxidant activity, like glutathione peroxidase (GPx) and thioredoxin reductase (TrxR) …

The synthesis of iodolopyrazolium triflates via an oxidative cyclization of 3-(2-iodophenyl)-1
H-pyrazoles is described. The reaction is characterized by a broad substrate scope, and …

The selenophene derivatives are an important class of selenium-based heterocyclics. These
compounds play an important role in prospecting new drugs, as well as in the development …

A new method was developed for the synthesis of 4-chalcogenyl-1 H-isochromen-1-ones
through the 6-endo-dig electrophilic cyclization of 2-alkynylaryl esters and diorganyl …

Copper-catalyzed direct selenation of substituted 2-bromo-N-phenylbenzamide substrates
with elemental selenium powder provided a series of methoxy-substituted isoselenazolones …

Novel N-methylated ebselenamine antioxidants were prepared from the corresponding
diselenides with iodomethane. All ebselenamines showed excellent chain-breaking and …

A novel methodology to accelerate annulation reactions leading to condensed selenium
heterocycles was developed. The reactions of selenium dihalides with methyleugenol, allyl …

The step-by-step redox process of bis-[2-phenyl-1, 2-benzisoselenazol-3 (2H)-one-7-yl]
diazene ie azo-bis-ebselen in the presence of PhSH and H2O2 was reported using 77Se …
