Synthesis of quinoxalines by cyclization of α-arylimino oximes of α-dicarbonyl compounds Synthesis of quinoxalines by cyclization of α-arylimino oximes of α-dicarbonyl compounds Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-212000enHeating the title compounds 1 at reflux in acetic anhydride yields quinoxalines 3 and 4 via a presumed aryliminoiminyl radical 5, resulting from homolytic cleavage of the NO bond in the intermediate ester 2. The observed regioselectivity of the reaction is also rationalized by implicating such a radical.http://creativecommons.org/licenses/by/4.0/Tetrahedron Letters415210299-10302 Xekoukoulotakis Nikos Ξεκουκουλωτακης Νικος A.J Maroulis C.P Hadjiantoniou-Maroulis Elsevier
