The thiol peroxidase-like activity of a series of novel functionalized tellurium containing catalysts has been investigated with different models. Dialkyl- and aryl-alkyl-tellurides, conveniently achieved through the ring opening of strained heterocycles, exhibited remarkable catalytic antioxidant activity, being able to reduce hydrogen peroxide in the presence of different thiols (benzenethiol, dithiothreitol and glutathione) under different conditions. The nature of the β-substituent strongly influenced the performances of the studied catalysts, thus giving useful criteria for the design of good synthetic mimics of glutathione peroxidase. The catalytic activity of functionalized organotellurides has been compared with that of their selenated analogues, showing as the latter behave as less efficient catalysts.
Construction of tetrahydrofuran-3-ones from readily available organochalcogen precursors via radical carbonylation/reductive cyclization
Berlin, Stefan,Ericsson, Cecilia,Engman, Lars
, p. 3 - 6 (2007/10/03)
(matrix presented) β-Hydroxyalkyl aryl chalcogenides, readily available by regioselective ring-opening of epoxides with nucleophilic benzeneselenolate or tellurolate, were O-alkylated by treatment with ethyl propiolate or (E)-1,2-bis(phenylsulfonyl)ethyle
