Redox relay是什么

WebAn electrochemical ‘redox-relay’ system has been developed which allows the generation of C-centered radicals. Intermolecular ‘tin-like’ radical reactions can subsequently be conducted under the most benign of conditions. The yields and efficiency of the processes are competitive and even superior in most WebWe envision that this radical redox-relay strategy could be extended to the synthesis of allylic alcohols with the introduction of a Co co-cata-lyst. In the proposed reaction, we …

WebThe redox relay generates disulfide-linked STAT3 oligomers with attenuated transcriptional activity. Cytokine-induced STAT3 signaling is accompanied by Prx2 and STAT3 oxidation and is modulated by Prx2 expression levels. It is shown that the thiol peroxidase peroxiredoxin-2 (Prx2), one of the most H(2)O(2)-reactive proteins in the cell, acts as ... WebThe rearrangement of epoxides to form allylic alcohols is a net redox-neutral transformation. To circumvent the use of a base promoter, we envision that this reaction could be achieved by combining a pair of sin-gle-electron oxidation and reduction events in the same catalytic cycle. This strategy, which we named radical redox-relay (Scheme 1A ...
