Reaction conditions: substrate (0.3 mmol, 1 equiv), MesAcrPh+ (2.5 mol%), Cu(EH)2 (2 equiv), TFA (1 equiv), and 1,2-DCE. irradiated for 8–96 h. Diastereomer and regioisomer ratios were determined by 1H NMR analysis of the unpurified reaction mixtures.
p-TsOH (2 equiv) instead of TFA.
p-TsOH (1 equiv) instead of TFA.
Reaction irradiated for 30 min.
