Tandem radical cyclisation and translocation approaches to biologically important mitomycin ring systems

Allan, Gillian M.,Parsons, Andrew F.,Pons, Jean-Fran?ois

, p. 1431 - 1434 (2007/10/03)

New free-radical cyclisation and translocation approaches to the tricyclic mitomycin ring system have been developed. These convergent approaches involve either a tandem 5-endo/5-exo radical cyclisation or alternatively, a 1,6-hydrogen-atom transfer follo
