Radical cyclization reactions produce mono- or polycyclic products through the action of radical intermediates. Because they are intramolecular transformations, they are often very rapid and selective. Selective radical generation can be achieved at carbons bound to a variety of functional groups, and reagents used to effect radical generation are numerous. The radical cyclization step usually involves the attack of a radical on a multiple bond. After this step occurs, the resulting cy… Web1 de dez. de 2016 · Finn's group described the Wang-resin based peptide head-to-tail CuAAC cyclization under copper catalyst [10].In their studies, 11-mer and 19-mer …
