Abstract
A new and convenient synthesis of 2-aryl-2,3-dihydroquinolin-4(1H)-ones has been described using the intramolecular cyclization of 2-aminochalcones catalyzed by 1-octyl-4-aza-1-azoniabicyclo[2.2.2]octane bromide ([C8dabco]Br). Recyclability of the catalyst, high yields, simple isolation of the products, and high atom economy are the noteworthy aspects of the protocol.
