Abstract
Copper(I)- and palladium(II)-catalyzed cyclizations enable a convenient synthesis of functionalized imidazo[1,2-a]pyridine aldehydes/ketones and 3-vinyl imidazo[1,2-a]pyridines. These one-pot reactions proceed smoothly with commercially available catalysts and afford the products in good yields.
