Selective 6-endo cyclization of the acyl radicals onto the nitrogen of imine and oxazoline C-N bonds.
Acyl radicals generated by the addition of alkyl or vinyl radicals to carbon monoxide cyclized onto the C-N bonds of imines and oxazoline with perfect 6-endo selectivity, driven by a preference for attack at nitrogen.
