ethoxy alkynes are performed at 120−130 °C, whereas tert-butoxy derivatives undergo the retro-ene reaction at 90 °C. With the exception of primary, unbranched amines, potential side reactions involving addition of the amines to carbon dioxide are not competitive with the desired C−N bond-forming reaction. The amide synthesis is applicable to the preparation of β-hydroxy and β-amino amide derivatives
