Manganese-mediated radicaladdition reactions to chiral N-acylhydrazones produces amines with excellent stereocontrol, but prior work showed an incompatibility with aromatic N-heterocycles. Control reactions with various aromatic heterocycles as additives led to modified reaction conditions that permit improved radicaladditions to N-acylhydrazones in the presence of heteroaromatic compounds. The method
