title: Synthesis of the N2-deoxyguanosine adduct of the potent dietary mutagen IQ.
abstract: [structure: see text] After bioactivation, the potent dietary mutagen 2-amino-3-methylimidazo[4,5-f]-quinoline (IQ) reacts with DNA to give two regioisomeric adducts of deoxyguanosine. The synthesis of the minor N2-adduct has been achieved utilizing the Buchwald-Hartwig palladium-catalyzed N-arylation reaction as the key step.
