The first computational study for the oxidative aromatization of pyrazolines and 1,4-dihydropyridines using 1,2,4-triazolinediones: an anomeric-based oxidation

Abstract

The oxidative aromatization of 1,3,5-trisubstituted pyrazolines and 1,4-dihydropyridines using 1,2,4-triazolinediones as oxidizing agents was studied. It is confirmed that the “anomeric-based oxidation” passes through a concerted oxidation<italic>via</italic>hydrogen abstraction–addition.
