WebPubMed Central (PMC) 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… delete block family account user on computerWeb18 de jan. de 2024 · Key features of the final process include construction of the benzothiophene core via Higa cyclization, late-stage phenolation using a Pd-catalyzed hydroxylation of an aryl bromide and end-game ... delete blank rows from excel sheet
