FeCl3-catalyzed formation of indolizine derivatives via the 1,3-dipolar cycloaddition reaction between azomethine ylides and chalcones or dibenzylideneacetones
The FeCl3-catalyzed 1,3-dipolar cycloaddition reaction of pyridinium-1-yl(quinolin-2-yl)methanide, prepared in situ from the iodine catalyzed reaction of 2-methylquinoline and pyridine in the presence of base, with chalcones or dibenzylideneacetones, in the one-pot synthesis of aryl(2-aryl-3-(quinolin-2-yl)indolizin-1-yl)methanones is described.
