… Thus, our results reveal that aromatization of a 4-n-alQ+1,4dihydropyridine in the prsence of
potassium permanganate can occur following two competitive mechanisms depending on the
experimental conditions: the expected ionic pathway13 yields 2 whereas a radical pathway
yields 3. For the other derivatives (R’ = benzyl, secondary alkyl, aryl), the competition is not
apparent. This can be rationalixed as foJJows: the ionic pathway proceeds through expulsion …
