1,1-Cyclopropane aminoketones were efficiently synthesized in high yields by the tandem reaction of -amino aryl ketones with vinyl sulfonium salts using DBU as the base in CH 2 Cl 2 . This methodology was utilized to synthesize 2-benzoyl quinolines. 1,1-Cyclopropane aminoketones have been synthesized from vinyl sulfonium and -amino aryl ketones, subsequent transformations lead to 2-benzoyl quinolines.
