Systematic Control of Degree and Sense of Asymmetric Induction in Intramolecular Radical 1,5-C−H Amination of Sulfamoyl Azide by [Co(HuPhyrin)]a,b,c,d
a Reactions were performed on a 0.10 mmol scale of sulfamoyl azide 1a using 2 mol % of [Co(HuPhyrin)] in 1.0 mL of methyl tert-butyl ether (MTBE) at 40 °C; [1a] = 0.10 M. b Yields in the Supporting Information. c Absolute configuration determined by X-ray crystal structural analysis. d Enantiomeric ratios (er) determined by chiral HPLC analysis.
