Treatment of N-phenyl-iododifluoroacetamide (1) with terminal alkenes (2) in the presence of Na2S2O4 and NaHCO3 in CH3CN/H2O gave good yields of N-phenyl-2,2-difluoro-4-iodoalkanamide (3), which cyclized under strong basic conditions to afford N-phenyl-alpha,alpha-difluoro-gamma-lactams (4). Or simply, these lactams 4 can be directly prepared in one-pot from 1 and 2 in the presence of Na2S2O4 and NaOH. (C) 2011 Elsevier B.V. All rights reserved.
