Add to ORKGThe tripyridylamine cogper(I) halide complex mediates the atom transfer radical cyclisation of bromo-enamides to give beta -lactams exclusively with no formation of gamma -lactams. Initial products 7 arise from 4-exo bromine atom transfer but elimination can be readily achieved by reaction with DBU to furnish alkenes 8 in high yields (92-98%). (C) 2001 Elsevier Science Ltd.
