Cover Picture: Copper-Catalyzed Double Decarboxylative Coupling Reactions of Alkynyl Carboxylic Acid and Glyoxylic Acid: Synthesis of Propargyl Amines and Imidazopyridines (Asian J. Org. Chem. 6/2016).

A double decarboxylative coupling reaction was developed. Alkynyl carboxylic acids, glyoxylic acid, and amines were reacted in the presENce of a copper catalyst to afford the corresponding propargyl amines in good yields. It was found that the alkynyl carboxylic acid showed similar reactivity to a terminal alkyne, and the reactivity of glyoxylic acid was almost idENtical to that of an aldehyde in this coupling reaction.
