One-Pot Synthesis of Benzo[4,5]imidazo[1,2-a]quinazoline Derivatives via Facile Transition-Metal-Free Tandem Process
摘要:
A one-pot transition metal-free method for synthesizing benzo[4,5]imidazo[1,2-a]quinazoline and imidazo-[1,2-a]quinazoline derivatives has been developed. The approach is widely applicable to 2-fluoro-, 2-chloro-, 2-bromo- and 2-nitro-substituted aryl aldehyde and ketone substrates. The fluorescence properties of target compounds were studied.
