Catalytic aromatization of 1,4-dihydropyridines by radical cation salt prompted aerobic oxidation
摘要:
Aromatization of Hantzch 1,4-dihydropyridines was achieved under radical cation salt induced conditions, in which triarylamine radical cation acts as an efficient catalyst to prompt the aerobic oxidation of 1,4-DHPs in a catalytic way. (C) 2013 Elsevier Ltd. All rights reserved.
