Radical cyclization forming furan rings

Similar methodology was employed to the synthesis of more complex polycyclic ring system, as shown in Scheme 32 <1997TL9069>. The initial alkenyl radical 54, formed by an intramolecular radical 13-< 4t>-dig macro-cyclization, initiated a radical cascade reaction by first reacting at the a-position of the furan ring. [Pg.429]

Atom transfer radical cyclization reactions mediated by copper complexes to form furan and pyrrole rings, lactones and /f-lactams 02CSR1. [Pg.156]
