Productive trapping of NAD-type radicals. Non-biomimetic reduction of pyridinium saltsElectronic supplementary information (ESI) available: experimental procedure and characterization data. See: http://www.rsc.org/suppdata/cc/b2/b201813f/

Abstract

One-electron reduction of pyridinium salts (NAD+ analogues) generates dihydropyridyl radicals which may then be engaged in radical addition processes to regioselectively form gamma-substituted dihydropyridines.
