a-Iminoesters are known as versatile building blocks that allow access a wide range of molecular diversity such as the synthesis of a-amino acids and derivatives, pharmaceuticals, natural products, food additives, agrochemicals.Herein, we demonstrate the scope and limitations of the Lewis acid-catalyzed addition of potassium alkynyltrifluoroborate salts to a-iminoesters providing a-amino acid derivatives in good to high yields in mild conditions and short reaction times
