We have developed a new strategy for catalytic aminohydroxylation of olefins with an N-protected iminopyridinium ylide as the amine source. Iminopyridinium ylides N-protected with TFAc (trifluoroacetyl), Boc (tert-butoxycarbonyl), Troc (2,2,2-trichloroethoxycarbonyl), and Alloc (allyloxycarbonyl) groups serve as N-centered radical precursors when combined with fac-[Ir(ppy)3] photocatalysis and Sc(OTf)3
