Simple and Efficient Copper(I)‐Catalyzed Access to Three Versatile Aminocoumarin‐Based Scaffolds using Isocyanoacetate

Abstract An efficient method has been developed for the one‐pot copper(I)‐catalyzed synthesis of 3‐aminocoumarin and its derivatives, such as 3‐substituted methylideneaminocoumarins and chromeno[3,4‐ d ]imidazol‐4(1 H )‐ones. Significantly, the strategy presents a straightforward and efficient approach to constructing biologically useful molecular scaffolds.
