Synthesis of unstable cyclic peroxides for chemiluminescence studies

Peróxidos cíclicos de quatro membros são intermediários de alta energia importantes em diversas transformações quimi e bioluminescentes. Especificamente, a-peroxilactonas (1,2-dioxetanonas) têm sido consideradas sistemas modelo para a eficiente bioluminescência do vaga-lume. Contudo, a preparação deste tipo de compostos altamente instáveis é extremamente difícil e, por isso, apenas alguns pouco...

Selective synthesis of cyclic peroxides from triketones and H2O2.

A method for the assembly of tricyclic structures containing the peroxide, monoperoxyacetal, and acetal moieties was developed based on the acid-catalyzed reaction of β,δ-triketones with H(2)O(2). Tricyclic compounds are formed selectively in yields from 39% to 90% by the reactions with the use of large amounts of strong acids, such as H(2)SO(4), HClO(4), or HBF(4), which act both as the cataly...

The action of iron on amino acid and protein peroxides.

Protein oxidation by agents such as oxygen free radicals leads to changes in their stucture and function. Depending on the conditions of the oxidation, proteins can undergo chain scission and crosslinking, loss of amino acids, increase in susceptibility to proteolysis and heat denaturation and loss of biological activity [l-71. We have recently reported that, in addition to such alterations, so...
