Abstract

Chemistry Chemistry, Multidisciplinary Green & Sustainable Science & Technology Physical Sciences Science & Technology Science & Technology - Other Topics
Utilizing green technologies as microwave (MW) irradiation and ionic liquids (ILs), we could produce 1,3,5-trisubstituted benzene 3, 7, 9, and 14 by self-condensation of enamines 1, enaminones 4, 8, and enaminoester 10, respectively, in the presence of pyridinium chloride ([PyH]Cl) for short time. Also, we synthesized pyridine derivatives 17, upon irradiating enaminones 4 in domestic MW oven for short time.
